Business Card Printing Online in Oakdale Mn
Digital printing in Minnesota has been a door opener for many businesses. Because printers sell the same thing as everyone else, everyone tries to claim that their service, quality and price are better than others. For this reason, every printer has to find something that would separate them from everyone else. And some business owners find that they have increased productivity after using digital technology and short run processes. Somehow, these gains can be credited to a combination of better pricing and more efficient press performance. Let’s say you have greeting cards that need to be printed. Obsolete inventory through the use of short run digital press can be eliminated.

This is because with this technology you can print only the needed cards, thus, resulting to orders printed in the exact quantity required. But just the same this kind of printing system is not for everyone. There are risks and changes that need to be dealt with. Nevertheless, the printing industry will continue to change and improve in the years to come. Thus, all business owners and companies have to do is to determine whether this certain printing technique is what they need.

For other uses, see Kodak (disambiguation). The Eastman Kodak Company (referred to simply as Kodak) is an American technology company that produces imaging products with its historic basis on photography. The company is headquartered in Rochester, New York and is incorporated in New Jersey. Kodak provides packaging, functional printing, graphic communications and professional services for businesses around the world. Its main business segments are Print Systems, Enterprise Inkjet Systems, Micro 3D Printing and Packaging, Software and Solutions, and Consumer and Film. It is best known for photographic film products. Kodak was founded by George Eastman and Henry A. Strong on September 4, 1888. During most of the 20th century, Kodak held a dominant position in photographic film. The company's ubiquity was such that its "Kodak moment" tagline entered the common lexicon to describe a personal event that was demanded to be recorded for posterity. Kodak began to struggle financially in the late 1990s, as a result of the decline in sales of photographic film and its slowness in transitioning to digital photography. As a part of a turnaround strategy, Kodak began to focus on digital photography and digital printing, and attempted to generate revenues through aggressive patent litigation. In January 2012, Kodak filed for Chapter 11 bankruptcy protection in the United States District Court for the Southern District of New York. In February 2012, Kodak announced that it would stop making digital cameras, pocket video cameras and digital picture frames and focus on the corporate digital imaging market. In August 2012, Kodak announced its intention to sell its photographic film, commercial scanners and kiosk operations, as a measure to emerge from bankruptcy, but not its motion picture film operations. In January 2013, the Court approved financing for Kodak to emerge from bankruptcy by mid 2013. Kodak sold many of its patents for approximately $525,000,000 to a group of companies (including Apple, Google, Facebook, Amazon, Microsoft, Samsung, Adobe Systems and HTC) under the names Intellectual Ventures and RPX Corporation. On September 3, 2013, the company emerged from bankruptcy having shed its large legacy liabilities and exited several businesses. Personalized Imaging and Document Imaging are now part of Kodak Alaris, a separate company owned by the UK-based Kodak Pension Plan. On March 12, 2014, it announced that the board of directors had elected Jeffrey J. Clarke as chief executive officer and a member of its board of directors. The Kodak factory and main office in Rochester, circa 1910 From the company's founding by George Eastman in 1888, Kodak followed the razor and blades strategy of selling inexpensive cameras and making large margins from consumables – film, chemicals and paper. As late as 1976, Kodak commanded 90% of film sales and 85% of camera sales in the U.S. Japanese competitor Fujifilm entered the U.S. market (via Fuji Photo Film U.S.A.) with lower-priced film and supplies, but Kodak did not believe that American consumers would ever desert its brand. Kodak passed on the opportunity to become the official film of the 1984 Los Angeles Olympics; Fuji won these sponsorship rights, which gave it a permanent foothold in the marketplace. Fuji opened a film plant in the U.S., and its aggressive marketing and price cutting began taking market share from Kodak. Fuji went from a 10% share in the early 1990s to 17% in 1997. Fuji also made headway into the professional market with specialty transparency films such as Velvia and Provia, which competed successfully with Kodak's signature professional product, Kodachrome, but used the more economical and common E-6 processing machines which were standard in most processing labs, rather than the dedicated machines required by Kodachrome. Fuji's films soon also found a competitive edge in higher-speed negative films, with a tighter grain structure. In May 1995, Kodak filed a petition with the US Commerce Department under section 301 of the Commerce Act arguing that its poor performance in the Japanese market was a direct result of unfair practices adopted by Fuji. The complaint was lodged by the United States with the World Trade Organization. On January 30, 1998, the WTO announced a "sweeping rejection of Kodak's complaints" about the film market in Japan. Kodak's financial results for the year ending December 1997 showed that company's revenues dropped from $15.97 billion in 1996 to $14.36 billion in 1997, a fall of more than 10%; its net earnings went from $1.29 billion to just $5 million for the same period. Kodak's market share declined from 80.1% to 74.7% in the United States, a one-year drop of five percentage points that had observers suggesting that Kodak was slow to react to changes and underestimated its rivals. Although from the 1970s both Fuji and Kodak recognized the upcoming threat of digital photography, and although both sought diversification as a mitigation strategy, Fuji was more successful at diversification. The Kodak 'K' logo was introduced in 1971. The version seen here – with the 'Kodak' name in a more modern typeface – was used from 1987 until the logo's discontinuation in 2006, but later used again in 2016 Kodak logo from 2006 to 2016 Although Kodak developed a digital camera in 1975, the first of its kind, the product was dropped for fear it would threaten Kodak's photographic film business. In the 1990s, Kodak planned a decade-long journey to move to digital technology. CEO George M. C. Fisher reached out[clarification needed] to Microsoft and other new consumer merchandisers. Apple's pioneering QuickTake consumer digital cameras, introduced in 1994, had the Apple label but were produced by Kodak. The DC-20 and DC-25 launched in 1996. Overall, though, there was little implementation of the new digital strategy. Kodak's core business faced no pressure from competing technologies, and as Kodak executives could not fathom a world without traditional film there was little incentive to deviate from that course. Consumers gradually switched to the digital offering from companies such as Sony. In 2001 film sales dropped, which was attributed by Kodak to the financial shocks caused by the September 11 attacks. Executives hoped that Kodak might be able to slow the shift to digital through aggressive marketing. Under Daniel Carp, Fisher's successor as CEO, Kodak made its move in the digital camera market, with its EasyShare family of digital cameras. Kodak spent tremendous resources studying customer behavior, finding out that women in particular loved taking digital photos but were frustrated in moving them to their computers. This key unmet consumer need became a major opportunity. Once Kodak got its product development machine started, it released a wide range of products which made it easy to share photos via PCs. One of their key innovations was a printer dock, where consumers could insert their cameras into this compact device, press a button, and watch their photos roll out. By 2005, Kodak ranked No. 1 in the U.S. in digital camera sales that surged 40% to $5.7 billion. Despite the high growth, Kodak failed to anticipate how fast digital cameras became commodities, with low profit margins, as more companies entered the market in the mid-2000s. In 2001 Kodak held the No. 2 spot in U.S. digital camera sales (behind Sony) but it lost $60 on every camera sold, while there was also a dispute between employees from its digital and film divisions. The film business, where Kodak enjoyed high profit margins, fell 18% in 2005. The combination of these two factors resulted in disappointing profits overall. Its digital cameras soon became undercut by Asian competitors that could produce their offerings more cheaply. Kodak had a 27% market-leading share in 1999, that dwindled to 15% by 2003. In 2007 Kodak was No. 4 in U.S. digital camera sales with a 9.6% share, and by 2010 it held 7% in seventh place behind Canon, Sony, Nikon and others, according to research firm IDC. Also an ever-smaller percentage of digital pictures were being taken on dedicated digital cameras, being gradually displaced in the late 2000s by cameras on cellphones, smartphones, and tablets. The decline of camera film to digital greatly affected Kodak's business. Kodak's main headquarters in Rochester, New York Kodak then began a strategy shift: Previously Kodak had done everything in-house, but CEO Antonio Pérez shut down film factories and eliminated 27,000 jobs as it outsourced its manufacturing. Pérez invested heavily in digital technologies and new services that capitalized on its technology innovation to boost profit margins. He also spent hundreds of millions of dollars to build up a high-margin printer ink business to replace shriveling film sales. Kodak's ink strategy rejected the razor and blades business model used by the dominant market leader Hewlett-Packard in that Kodak's printers were expensive but the ink was cheaper. As of 2011, these new lines of inkjet printers were said to be on verge of turning a profit, although some analysts were skeptical as printouts had been replaced gradually by electronic copies on computers, tablets, and smartphones. Home photograph printers, high-speed commercial inkjet presses, workflow software, and packaging were viewed as the company's new core businesses, with sales from those four businesses projected to double to nearly $2 billion in revenue in 2013 and account for 25% of all sales. However, while Kodak named home printers as a core business as late as August 2012, at the end of September declining sales forced Kodak to announce an exit from the consumer inkjet market. Kodak has also turned to litigation in order to generate revenue. In 2010, it received $838 million from patent licensing that included a settlement with LG. In 2011, despite the turnaround progress, Kodak rapidly used up its cash reserves, stoking fears of bankruptcy; it had $957 million in cash in June 2011, down from $1.6 billion in January 2001. In 2011, Kodak reportedly explored selling off or licensing its vast portfolio of patents in order to stave off bankruptcy. By January 2012, analysts suggested that the company could enter bankruptcy followed by an auction of its patents, as it was reported to be in talks with Citigroup to provide debtor-in-possession financing. This was confirmed on January 19, 2012, when the company filed for Chapter 11 bankruptcy protection and obtained a $950 million, 18-month credit facility from Citigroup to enable it to continue operations. Under the terms of its bankruptcy protection, Kodak had a deadline of February 15, 2013 to produce a reorganization plan. In April 2013, Kodak showed its first Micro Four Thirds camera, to be manufactured by JK Imaging. On September 3, 2013, Kodak announced that it emerged from bankruptcy as a technology company focused on imaging for business. Its main business segments are Digital Printing & Enterprise and Graphics, Entertainment & Commercial Films. On March 12, 2014, Kodak announced that Jeffrey J. Clarke had been named the new CEO. On January 1, 2015, Kodak announced a new five business division structure; Print Systems, Enterprise Inkjet Systems, Micro 3D Printing and Packaging, Software and Solutions, and Consumer and Film.

Its main business segments are Print Systems, Enterprise Inkjet Systems, Micro 3D Printing and Packaging, Software and Solutions, and Consumer and Film. Kodak provides high-speed, high-volume commercial inkjet, and color and black-and-white electrophotographic printing equipment and related consumables and services. It has an installed base of more than 5,000 units. Its Prosper platform uses Stream inkjet technology, which delivers a continuous flow of ink that enables constant and consistent operation, with uniform size and accurate placement, even at very high print speeds. Applications for Prosper include publishing, commercial print, direct mail, and packaging. The business also includes the customer base of Kodak VersaMark products. The NexPress platform is used for printing short-run, personalized print applications for purposes such as direct mail, books, marketing collateral and photo products. The Digimaster platform uses monochrome electrophotographic printing technology to create high-quality printing of statements, short-run books, corporate documentation, manuals and direct mail. Kodak designs and manufactures products for flexography printing. Its Flexcel line of flexo printing systems allow label printers to produce their own digital plates for customized flexo printing and flexible printed packaging. The company currently has strategic relationships with worldwide touch-panel sensor leaders, such as the partnerships with UniPixel announced on April 16, 2013 and Kingsbury Corp. launched on June 27, 2013. Enterprise professional services offers print and managed media services, brand protection solutions and services, and document management services to enterprise customers, including government, pharmaceuticals, and health, consumer and luxury good products, retail and finance. In 1997, Heidelberg Printing Machines AG and Eastman Kodak Co. had created the Nexpress Solutions LLC joint venture to develop a digital color printing press for the high-end market segment. Heidelberg acquired Eastman Kodak Co.'s Office Imaging black and white digital printing activities in 1999. In 2000, they had launched Digimaster 9110 - Black & White Production Printer and NexPress 2100 Digital Color Press. In March 2004, Heidelberg transferred its Digital Print division to Eastman Kodak Co. under mutual agreement. Kodak continues to research and develop Digital Printing Systems and introduced more products. At present, Kodak has commercial Web-fed presses, commercial imprinting systems - Prosper, VersaMark and commercial sheet-fed press - NexPress digital production color press, DIGIMASTER HD digital black and white production printer. Kodak entered into consumer inkjet photo printers in a joint venture with manufacturer Lexmark in 1999 with the Kodak Personal Picture Maker. In February 2007, Kodak re-entered the market with a new product line of All-In-One (AiO) inkjet printers that employ several technologies marketed as Kodacolor Technology. Advertising emphasizes low price for ink cartridges rather than for the printers themselves. Kodak announced plans to stop selling inkjet printers in 2013 as it focuses on commercial printing, but will still sell ink. Kodak's graphics business consists of computer to plate (CTP) devices, which Kodak first launched in 1995 when the company introduced the first thermal CTP to market. In CTP, an output device exposes a digital image using SQUAREspot laser imaging technology directly to an aluminum surface (printing plate), which is then mounted onto a printing press to reproduce the image. Kodak's Graphics portfolio includes front-end controllers, production workflow software, CTP output devices, and digital plates. Kodak’s Global Technical Services ("GTS") for Commercial Imaging is focused on selling service contracts for Kodak products, including the following service categories: field services, customer support services, educational services, and professional services. Kodak's Entertainment Imaging and Commercial Film group ("E&CF") encompasses its motion picture film business, providing motion imaging products (camera negative, intermediate, print and archival film), services and technology for the professional motion picture and exhibition industries. E&CF also offers Aerial and Industrial Films including KODAK Printed Circuit Board film, and delivers external sales for the company’s component businesses: Polyester Film, Specialty Chemicals, Inks and Dispersions and Solvent Recovery. The Kodak company played a role in the invention and development of the motion picture industry. Many cinema and TV productions are shot on Kodak film stocks. The company helped set the standard of 35mm film, and introduced the 16mm film format for home movie use and lower budget film productions. The home market-oriented 8mm and Super 8 formats were also developed by Kodak. Kodak also entered the professional television production video tape market, briefly in the mid-1980s, under the product portfolio name of Eastman Professional Video Tape Products. In 1990, Kodak launched a Worldwide Student Program working with university faculty throughout the world to help nurture the future generation of film-makers. Kodak formed Educational Advisory Councils in the US, Europe and Asia made up of deans and chairs of some of the most prestigious film schools throughout the world to help guide the development of their program. Kodak previously owned the visual effects film post-production facilities Cinesite in Los Angeles and London and also LaserPacific in Los Angeles. Kodak sold Cinesite to Endless LLP, an independent British private equity house. Kodak previously sold LaserPacific and its subsidiaries Laser-Edit, Inc, and Pacific Video, Inc., in April 2010 for an undisclosed sum to TeleCorps Holdings, Inc. Kodak also sold Pro-Tek Media Preservation Services, a film storage company in Burbank, California, in October 2013. Aside from technical phone support for its products, Kodak offers onsite service for other devices such as document scanners, data storage systems (optical, tape, and disk), printers, inkjet printing presses, microfilm/microfiche equipment, photograph kiosks, and photocopiers, for which it despatches technicians who make repairs in the field. Kodak markets Picture CDs and other photo products such as calendars, photo books and photo enlargements through retail partners such as CVS, Walmart and Target and through its Kodak Gallery online service, formerly known as Ofoto. A Kodak Instamatic 104 On January 13, 2004, Kodak announced it would stop marketing traditional still film cameras (excluding disposable cameras) in the United States, Canada and Western Europe, but would continue to sell film cameras in India, Latin America, Eastern Europe and China. By the end of 2005, Kodak ceased manufacturing cameras that used the Advanced Photo System. Kodak licensed the manufacture of Kodak branded cameras to Vivitar in 2005 and 2006. After 2007 Kodak did not license the manufacture of any film camera with the Kodak name. After losing a patent battle with Polaroid Corporation, Kodak left the instant camera business on January 9, 1986. The Kodak instant camera included models known as the Kodamatic and the Colorburst. Polaroid was awarded damages in the patent trial in the amount of $909,457,567, a record at the time. (Polaroid Corp. v. Eastman Kodak Co., U.S. District Court District of Massachusetts, decided October 12, 1990, case no. 76-1634-MA. Published in the U.S. Patent Quarterly as 16 USPQ2d 1481). See also the following cases: Polaroid Corp. v. Eastman Kodak Co., 641 F.Supp. 828 [228 USPQ 305] (D. Mass. 1985), stay denied, 833 F.2d 930 [5 USPQ2d 1080] (Fed. Cir.), aff'd, 789 F.2d 1556 [229 USPQ 561] (Fed. Cir.), cert. denied, 479 U.S. 850 (1986). Kodak was the exclusive supplier of negatives for Polaroid cameras from 1963 until 1969, when Polaroid chose to manufacture its own instant film. As part of its move toward higher end products, Kodak announced on September 15, 2006 that the new Leica M8 camera incorporates Kodak's KAF-10500 image sensor. This was the second recent partnership between Kodak and the German optical manufacturer. In 2011, Kodak sold its Image Sensor Solutions business to Platinum Equity, which subsequently renamed it Truesense Imaging, Inc. Main articles: Kodak DCS and Kodak EasyShare A Kodak Easyshare Z1015 IS digital camera Many of Kodak's early compact digital cameras were designed and built by Chinon Industries, a Japanese camera manufacturer. In 2004, Kodak Japan acquired Chinon and many of its engineers and designers joined Kodak Japan. The Kodak DCS series of digital single-lens reflex cameras and digital camera backs were released by Kodak in the 1990s and 2000s, and discontinued in 2005. They were based on existing 35mm film SLRs from Nikon and Canon and the range included the original Kodak DCS, the first commercially available digital SLR. In July 2006, Kodak announced that Flextronics would manufacture and help design its digital cameras. Kodak first entered the digital picture frame market with the Kodak Smart Picture Frame in the fourth quarter of 2000. It was designed by Weave Innovations and licensed to Kodak with an exclusive relationship with Weave's StoryBox online photo network. Smart Frame owners connected to the network via an analog telephone connection built into the frame. The frame could hold 36 images internally and came with a six-month free subscription to the StoryBox network. Kodak re-entered the digital photo frame market at CES in 2007 with the introduction of four new EasyShare-branded models that were available in sizes from 200 to 280 mm (7.9 to 11.0 in), included multiple memory card slots, and some of which included Wi-Fi capability to connect with the Kodak Gallery—that gallery functionality has now been compromised due to gallery policy changes (see below). Main article: Kodak Gallery In June 2001, Kodak purchased the photo-developing website Ofoto, later renamed Kodak Gallery. The website enables users to upload their photos into albums, publish them into prints, and create mousepads, calendars, etc. On March 1, 2012, Kodak announced that it sold Kodak Gallery to Shutterfly for $23.8 million. Kodak provides scanning technology. Historically this industry began when George Eastman partnered with banks to image checks in the 1920s. Through the development of microfilm technology, Eastman Kodak was able to provide long term document storage. Document imaging was one of the first imaging solutions to move to "digital imaging" technology. Kodak manufactured the first digital document scanners for high speed document imaging. Today Kodak has a full line of document scanners for banking, finance, insurance, healthcare and other vertical industries. Kodak also provides associated document capture software and business process services. Eastman Kodak acquired the Bowe Bell & Howell scanner division in September 2009. Kodak continues to produce specialty films and film for newer and more popular consumer formats, but it has discontinued the manufacture of film in older and less popular formats. Kodak is a leading producer of silver halide (AgX) paper used for printing from film and digital images. Minilabs located in retail stores and larger central photo lab operations (CLOs) use silver halide paper for photo printing. In 2005 Kodak announced it would stop producing black-and-white photo paper. A Kodak NexPress 2500 digital printing press Kodak is a manufacturer of self-service photo kiosks that produce "prints in seconds" from multiple sources including digital input, scanned prints, Facebook, the Kodak Gallery and orders placed on-line using thermosublimation printers. The company has placed over 100,000 Picture Kiosks in retail locations worldwide. Employing similar technology, Kodak also offers larger printing systems with additional capabilities including duplex greeting cards, large format poster printers, photobooks and calendars under the brand name "APEX". 1900 Kodak ad The letter k was a favorite of Eastman's; he is quoted as saying, "it seems a strong, incisive sort of letter." He and his mother devised the name Kodak with an anagrams set. Eastman said that there were three principal concepts he used in creating the name: it should be short, easy to pronounce, and not resemble any other name or be associated with anything else. The Kodak Research Laboratories were founded in 1912 with Kenneth Mees as the first director. Principal components of the Kodak Research Laboratories were the Photographic Research Laboratories and then the Imaging Research Laboratories. Additional organizations included the Corporate Research Laboratories. Over nearly a century, scientists at these laboratories produced thousands of patents and scientific publications. George Eastman In 2005, Kodak Canada donated its entire historic company archives to Ryerson University in Toronto. The Ryerson University Library also acquired an extensive collection of materials on the history of photography from the private collection of Nicholas M. & Marilyn A. Graver of Rochester, New York. The Kodak Archives, begun in 1909, contain the company's Camera Collection, historic photos, files, trade circulars, Kodak magazines, price lists, daily record books, equipment, and other ephemera. It includes the contents of the Kodak Heritage Collection Museum, a museum established in 1999 for Kodak Canada's centennial that Kodak closed in 2005 along with the company's entire 'Kodak Heights' manufacturing campus in Mount Dennis, Toronto. See also: George Eastman House. On March 26, 2007, the Council of Better Business Bureaus (CBBB) announced that Eastman Kodak was resigning its national membership in the wake of expulsion proceedings initiated by the CBBB board of directors. In 2006, Kodak notified the BBB of Upstate New York that it would no longer accept or respond to consumer complaints submitted by them. In prior years, Kodak responded by offering consumers an adjustment or an explanation of the company’s position. The BBB file contains consumer complaints of problems with repairs of Kodak digital cameras, as well as difficulty communicating with Kodak customer service. Among other complaints, consumers say that their cameras broke and they were charged for repairs when the failure was not the result of any damage or abuse. Some say their cameras failed again after being repaired. Kodak said its customer service and customer privacy teams concluded that 99% of all complaints forwarded by the BBB already were handled directly with the customer. Brian O’Connor, Kodak chief privacy officer, said the company was surprised by the news release distributed by the Better Business Bureau: It is inaccurate in the facts presented as well as those the BBB chose to omit. Ironically, we ultimately decided to resign our membership because we were extremely unhappy with the customer service we received from the local office of the BBB. After years of unproductive discussions with the local office regarding their Web site postings about Kodak, which in our view were consistently inaccurate, we came to the conclusion that their process added no value to our own. Our commitment to our customers is unwavering. That will not change. What has changed is that, for us, the BBB's customer complaint process has become redundant, given the multiple and immediate ways that customers have to address their concerns directly with Kodak. In 2010, Apple filed a patent-infringement claim against Kodak. On May 12, 2011, Judge Robert Rogers rejected Apple's claims that two of its digital photography patents were being violated by Kodak. On July 1, 2011, the U.S. International Trade Commission partially reversed a January decision by an administrative law judge stating that neither Apple nor Research in Motion had infringed upon Kodak's patents. The ITC remanded the matter for further proceedings before the ALJ.
Digital Color Prints vs Color CopiesFront and back of Canon PowerShot A95, a typical pocket-size digital camera Hasselblad 503CW with Ixpress V96C digital back, an example of a professional digital camera system Nikon D810 A digital camera or digicam is a camera that produces digital images that can be stored in a computer, displayed on a screen and printed. Most cameras sold today are digital, and digital cameras are incorporated into many devices ranging from PDAs and mobile phones (called camera phones) to vehicles. Digital and movie cameras share an optical system, typically using a lens with a variable diaphragm to focus light onto an image pickup device. The diaphragm and shutter admit the correct amount of light to the imager, just as with film but the image pickup device is electronic rather than chemical. However, unlike film cameras, digital cameras can display images on a screen immediately after being recorded, and store and delete images from memory. Many digital cameras can also record moving videos with sound. Some digital cameras can crop and stitch pictures and perform other elementary image editing. Further information: History of the camera § Digital cameras, Digital single-lens reflex camera, and Camera phone The history of the digital camera began with Eugene F. Lally of the Jet Propulsion Laboratory, who was thinking about how to use a mosaic photosensor to capture digital images. His 1961 idea was to take pictures of the planets and stars while travelling through space to give information about the astronauts' position. As with Texas Instruments employee Willis Adcock's filmless camera (US patent 4,057,830) in 1972, the technology had yet to catch up with the concept. Steven Sasson as an engineer at Eastman Kodak invented and built the first electronic camera using a charge-coupled device image sensor in 1975. Earlier ones used a camera tube; later ones digitized the signal. Early uses were mainly military and scientific; followed by medical and news applications. In 1986, Japanese company Nikon introduced the first digital single-lens reflex (DSLR) camera, the Nikon SVC. In the mid-to-late 1990s, DSLR cameras became common among consumers. By the mid-2000s, DSLR cameras had largely replaced film cameras. In 2000, Sharp introduced the world's first digital camera phone, the J-SH04 J-Phone, in Japan. By the mid-2000s, higher-end cell phones had an integrated digital camera. By the beginning of the 2010s, almost all smartphones had an integrated digital camera. Further information: Image sensor The two major types of digital image sensor are CCD and CMOS. A CCD sensor has one amplifier for all the pixels, while each pixel in a CMOS active-pixel sensor has its own amplifier. Compared to CCDs, CMOS sensors use less power. Cameras with a small sensor use a back-side-illuminated CMOS (BSI-CMOS) sensor. Overall final image quality is more dependent on the image processing capability of the camera, than on sensor type. The resolution of a digital camera is often limited by the image sensor that turns light into discrete signals. The brighter the image at a given point on the sensor, the larger the value that is read for that pixel. Depending on the physical structure of the sensor, a color filter array may be used, which requires demosaicing to recreate a full-color image. The number of pixels in the sensor determines the camera's "pixel count". In a typical sensor, the pixel count is the product of the number of rows and the number of columns. For example, a 1,000 by 1,000 pixel sensor would have 1,000,000 pixels, or 1 megapixel. Image at left has a higher pixel count than the one to the right, but has lower spatial resolution. Final quality of an image depends on all optical transformations in the chain of producing the image. Carl Zeiss points out at the weakest link in an optical chain determines the final image quality. In case of a digital camera, a simplistic way of expressing it is that the lens determines the maximum sharpness of the image while the image sensor determines the maximum resolution. The illustration on the right can be said to compare a lens with very poor sharpness on a camera with high resolution, to a lens with good sharpness on a camera with lower resolution. At the heart of a digital camera is a CCD or a CMOS image sensor. Digital camera, partly disassembled. The lens assembly (bottom right) is partially removed, but the sensor (top right) still captures an image, as seen on the LCD screen (bottom left). Since the first digital backs were introduced, there have been three main methods of capturing the image, each based on the hardware configuration of the sensor and color filters. Single-shot capture systems use either one sensor chip with a Bayer filter mosaic, or three separate image sensors (one each for the primary additive colors red, green, and blue) which are exposed to the same image via a beam splitter (see Three-CCD camera). Multi-shot exposes the sensor to the image in a sequence of three or more openings of the lens aperture. There are several methods of application of the multi-shot technique. The most common originally was to use a single image sensor with three filters passed in front of the sensor in sequence to obtain the additive color information. Another multiple shot method is called Microscanning. This method uses a single sensor chip with a Bayer filter and physically moved the sensor on the focus plane of the lens to construct a higher resolution image than the native resolution of the chip. A third version combined the two methods without a Bayer filter on the chip. The third method is called scanning because the sensor moves across the focal plane much like the sensor of an image scanner. The linear or tri-linear sensors in scanning cameras utilize only a single line of photosensors, or three lines for the three colors. Scanning may be accomplished by moving the sensor (for example, when using color co-site sampling) or by rotating the whole camera. A digital rotating line camera offers images of very high total resolution. The choice of method for a given capture is determined largely by the subject matter. It is usually inappropriate to attempt to capture a subject that moves with anything but a single-shot system. However, the higher color fidelity and larger file sizes and resolutions available with multi-shot and scanning backs make them attractive for commercial photographers working with stationary subjects and large-format photographs. Improvements in single-shot cameras and image file processing at the beginning of the 21st century made single shot cameras almost completely dominant, even in high-end commercial photography. The Bayer arrangement of color filters on the pixel array of an image sensor. Most current consumer digital cameras use a Bayer filter mosaic in combination with an optical anti-aliasing filter to reduce the aliasing due to the reduced sampling of the different primary-color images. A demosaicing algorithm is used to interpolate color information to create a full array of RGB image data. Cameras that use a beam-splitter single-shot 3CCD approach, three-filter multi-shot approach, color co-site sampling or Foveon X3 sensor do not use anti-aliasing filters, nor demosaicing. Firmware in the camera, or a software in a raw converter program such as Adobe Camera Raw, interprets the raw data from the sensor to obtain a full color image, because the RGB color model requires three intensity values for each pixel: one each for the red, green, and blue (other color models, when used, also require three or more values per pixel). A single sensor element cannot simultaneously record these three intensities, and so a color filter array (CFA) must be used to selectively filter a particular color for each pixel. The Bayer filter pattern is a repeating 2x2 mosaic pattern of light filters, with green ones at opposite corners and red and blue in the other two positions. The high proportion of green takes advantage of properties of the human visual system, which determines brightness mostly from green and is far more sensitive to brightness than to hue or saturation. Sometimes a 4-color filter pattern is used, often involving two different hues of green. This provides potentially more accurate color, but requires a slightly more complicated interpolation process. The color intensity values not captured for each pixel can be interpolated from the values of adjacent pixels which represent the color being calculated. Cameras with digital image sensors that are smaller than the typical 35mm film size have a smaller field or angle of view when used with a lens of the same focal length. This is because angle of view is a function of both focal length and the sensor or film size used. The crop factor is relative to the 35mm film format. If a smaller sensor is used, as in most digicams, the field of view is cropped by the sensor to smaller than the 35mm full-frame format's field of view. This narrowing of the field of view may be described as crop factor, a factor by which a longer focal length lens would be needed to get the same field of view on a 35mm film camera. Full-frame digital SLRs utilize a sensor of the same size as a frame of 35mm film. Common values for field of view crop in DSLRs using active pixel sensors include 1.3x for some Canon (APS-H) sensors, 1.5x for Sony APS-C sensors used by Nikon, Pentax and Konica Minolta and for Fujifilm sensors, 1.6 (APS-C) for most Canon sensors, ~1.7x for Sigma's Foveon sensors and 2x for Kodak and Panasonic 4/3-inch sensors currently used by Olympus and Panasonic. Crop factors for non-SLR consumer compact and bridge cameras are larger, frequently 4x or more. Further information: Image sensor format Relative sizes of sensors used in most current digital cameras. Digital cameras come in a wide range of sizes, prices and capabilities. In addition to general purpose digital cameras, specialized cameras including multispectral imaging equipment and astrographs are used for scientific, military, medical and other special purposes. Subcompact with lens assembly retracted Disassembled compact digital camera Compact cameras are intended to be portable (pocketable) and are particularly suitable for casual "snapshots". Many incorporate a retractable lens assembly that provides optical zoom. In most models, an auto actuating lens cover protects the lens from elements. Most ruggedized or water-resistant models do not retract, and most with (superzoom) capability do not retract fully. Compact cameras are usually designed to be easy to use. Almost all include an automatic mode, or "auto mode", which automatically makes all camera settings for the user. Some also have manual controls. Compact digital cameras typically contain a small sensor which trades-off picture quality for compactness and simplicity; images can usually only be stored using lossy compression (JPEG). Most have a built-in flash usually of low power, sufficient for nearby subjects. A few high end compact digital cameras have a hotshoe for connecting to an external flash. Live preview is almost always used to frame the photo on an integrated LCD. In addition to being able to take still photographs almost all compact cameras have the ability to record video. Compacts often have macro capability and zoom lenses, but the zoom range (up to 30x) is generally enough for candid photography but less than is available on bridge cameras (more than 60x), or the interchangeable lenses of DSLR cameras available at a much higher cost. Autofocus systems in compact digital cameras generally are based on a contrast-detection methodology using the image data from the live preview feed of the main imager. Some compact digital cameras use a hybrid autofocus system similar to what is commonly available on DSLRs. Some high end travel compact cameras have 30x optical zoom have full manual control with lens ring, electronic viewfinder, Hybrid Optical Image Stabilization, built-in flash, Full HD 60p, RAW, burst shooting up to 10fps, built-in Wi-Fi with NFC and GPS altogether. Typically, compact digital cameras incorporate a nearly silent leaf shutter into the lens but play a simulated camera sound  for skeuomorphic purposes. For low cost and small size, these cameras typically use image sensor formats with a diagonal between 6 and 11 mm, corresponding to a crop factor between 7 and 4. This gives them weaker low-light performance, greater depth of field, generally closer focusing ability, and smaller components than cameras using larger sensors. Some cameras use a larger sensor including, at the high end, a pricey full-frame sensor compact camera, such as Sony Cyber-shot DSC-RX1, but have capability near that of a DSLR. A variety of additional features are available depending on the model of the camera. Such features include ones such as GPS, compass, barometer and altimeter for above mean sea level or under(water) mean sea level. and some are rugged and waterproof. Starting in 2011, some compact digital cameras can take 3D still photos. These 3D compact stereo cameras can capture 3D panoramic photos with dual lens or even single lens for play back on a 3D TV. In 2013, Sony released two add-on camera models without display, to be used with a smartphone or tablet, controlled by a mobile application via WiFi. Rugged compact cameras typically include protection against submersion, hot and cold conditions, shock and pressure. Terms used to describe such properties include waterproof, freezeproof, heatproof, shockproof and crushproof, respectively. Nearly all major camera manufacturers have at least one product in this category. Some are waterproof to a considerable depth up to 82 feet (27 m); others only 10 feet (3m), but only a few will float. Ruggeds often lack some of the features of ordinary compact camera, but they have video capability and the majority can record sound. Most have image stabilization and built-in flash. Touchscreen LCD and GPS do not work underwater. For more details on this topic, see Action camera. GoPro and other brands offer action cameras which are rugged, small and can be easily attached to helmet, arm, bicycle, etc. Most have wide angle and fixed focus, and can take still pictures and video, typically with sound. The rising popularity of action camera is in line with many people want to share its photos or videos in social media, many competitors of action camera manufacturer means also many options with decreasing price and nowadays bundle sales with its waterproof housing and accessories mounting compatible with GoPro mounting are usual. The 360-degree camera can take picture or video 360 degrees using two lenses back-to-back and shooting at the same time. Some of the cameras are Ricoh Theta S, Nikon Keymission 360 and Samsung Gear 360. Nico360 was launched in 2016 and claimed as the world's smallest 360-degree camera with size 46 x 46 x 28 mm (1.8 x 1.8 x 1.1 in) and price less than $200. With virtual reality mode built-in stitching, Wifi, and Bluetooth, live streaming can be done. Due to it also being water resistant, the Nico360 can be used as action camera. There are tend that action cameras have capabilities to shoot 360 degrees with at least 4K resolution. Sony DSC-H2 Main article: Bridge camera Bridge cameras physically resemble DSLRs, and are sometimes called DSLR-shape or DSLR-like. They provide some similar features but, like compacts, they use a fixed lens and a small sensor. Some compact cameras have also PSAM mode. Most use live preview to frame the image. Their usual autofocus is by the same contrast-detect mechanism as compacts, but many bridge cameras have a manual focus mode and some have a separate focus ring for greater control. Big physical size and small sensor allow superzoom and wide aperture. Bridgcams generally include an image stabilization system to enable longer handheld exposures, sometimes better than DSLR for low light condition. As of 2014, bridge cameras come in two principal classes in terms of sensor size, firstly the more traditional 1/2.3" sensor (as measured by image sensor format) which gives more flexibility in lens design and allows for handholdable zoom from 20 to 24mm (35mm equivalent) wide angle all the way up to over 1000 mm supertele, and secondly a 1" sensor that allows better image quality particularly in low light (higher ISO) but puts greater constraints on lens design, resulting in zoom lenses that stop at 200mm (constant aperture, e.g. Sony RX10) or 400mm (variable aperture, e.g. Panasonic Lumix FZ1000) equivalent, corresponding to an optical zoom factor of roughly 10 to 15. Some bridge cameras have a lens thread to attach accessories such as wide-angle or telephoto converters as well as filters such as UV or Circular Polarizing filter and lens hoods. The scene is composed by viewing the display or the electronic viewfinder (EVF). Most have a slightly longer shutter lag than a DSLR. Many of these cameras can store images in a raw format in addition to supporting JPEG. The majority have a built-in flash, but only a few have a hotshoe. In bright sun, the quality difference between a good compact camera and a digital SLR is minimal but bridge cameras are more portable, cost less and have a greater zoom ability. Thus a bridge camera may better suit outdoor daytime activities, except when seeking professional-quality photos. Olympus OM-D E-M1 Mark II introduced 2016 Main article: Mirrorless interchangeable-lens camera In late 2008, a new type of camera emerged called mirrorless interchangeable-lens camera (MILC), which uses various sensors and offers lens interchangeability. These are simpler and more compact than DSLRs due to not having a lens reflex system. MILC camera models are available with various sensor sizes including: a small 1/2.3 inch sensor, as is commonly used in bridge cameras such as the original Pentax Q (more recent Pentax Q versions have a slightly larger 1/1.7 inch sensor); a 1 inch sensor; a Micro Four Thirds sensor; an APS-C sensor such as the Sony NEX series, Fujifilm X series, Pentax K-01, and Canon EOS M; and some, such as the Sony Alpha 7, use a full frame (35 mm) sensor and even Hasselblad X1D is the first medium format MILC. Disadvantage of MILC over DSLR is battery energy consume due to high energy consume of electronic viewfinder. Olympus and Panasonic released many Micro Four Thirds cameras with interchangeable lenses which are fully compatible each other without any adapter, while the others have proprietary mounts. In 2014, Kodak released its first Micro Four Third system camera. As of March 2014[update], MILC cameras are available which appeal to both amateurs and professionals. While most digital cameras with interchangeable lenses feature a lens-mount of some kind, there are also a number of modular cameras, where the shutter and sensor are incorporated into the lens module. The first such modular camera was the Minolta Dimâge V in 1996, followed by the Minolta Dimâge EX 1500 in 1998 and the Minolta MetaFlash 3D 1500 in 1999. In 2009, Ricoh released the Ricoh GXR modular camera. At CES 2013, Sakar International announced the Polaroid iM1836, an 18 MP camera with 1"-sensor with interchangeable sensor-lens. An adapter for Micro Four Thirds, Nikon and K-mount lenses was planned to ship with the camera. There are also a number of add-on camera modules for smartphones called lens-style cameras (lens camera). They contain all components of a digital camera in a module, but lack a viewfinder, display and most of the controls. Instead they can be mounted to a smartphone and use its display and controls. Lens-style cameras include: Cutaway of an Olympus E-30 DSLR Main article: Digital single-lens reflex camera Digital single-lens reflex cameras (DSLR) use a reflex mirror that can reflect the light and also can swivel from one position to another position and back to initial position. By default, the reflex mirror is set 45 degree from horizontal, blocks the light to the sensor and reflects light from the lens to penta-mirror/prism at the DSLR camera and after some reflections arrives at the viewfinder. The reflex mirror is pulled out horizontally below the penta-mirror/prism when shutter release is fully pressed, so the viewfinder will be dark and the light/image can directly strike the sensor at the time of exposure (speed setting). Autofocus is accomplished using sensors in the mirror box. Some DSLRs have a "live view" mode that allows framing using the screen with image from the sensor. These cameras have much larger sensors than the other types, typically 18 mm to 36 mm on the diagonal (crop factor 2, 1.6, or 1). The larger sensor permits more light to be received by each pixel; this, combined with the relatively large lenses provides superior low-light performance. For the same field of view and the same aperture, a larger sensor gives shallower focus. They use interchangeable lenses for versatility. Usually some lenses are made for digital SLR use only, but recent trend the lenses can also be used in detachable lens video camera with or without adapter. Main article: Sony SLT camera A DSLT uses a fixed translucent mirror instead of a moving reflex mirror as in DSLR. A translucent mirror or transmissive mirror or semi-transparent mirror is a mirror which reflects the light to two things at the same time. It reflects it along the path to a pentaprism/pentamirror which then goes to an optical view finder (OVF) as is done with a reflex mirror in DSLR cameras. The translucent mirror also sends light along a second path to the sensor. The total amount of light is not changed, just some of the light travels one path and some of it travels the other. The consequences are that DSLT cameras should shoot a half stop differently from DSL. One advantage of using a DSLT camera is the blind moments a DSLR user experiences while the reflecting mirror is moved to send the light to the sensor instead of the viewfinder do not exist for DSLT cameras. Because there is no time at which light is not traveling along both paths, DSLT cameras get the benefit of continuous auto-focus tracking. This is especially beneficial for burst mode shooting in low-light conditions and also for tracking when taking video. Until early 2014, only Sony had released DSLT cameras. By March 2014, Sony had released more DSLTs than DSLRs with a relatively complete lenses line-up. Main article: Rangefinder camera § Digital rangefinder A rangefinder is a device to measure subject distance, with the intent to adjust the focus of a camera's objective lens accordingly (open-loop controller). The rangefinder and lens focusing mechanism may or may not be coupled. In common parlance, the term "rangefinder camera" is interpreted very narrowly to denote manual-focus cameras with a visually-read out optical rangefinder based on parallax. Most digital cameras achieve focus through analysis of the image captured by the objective lens and distance estimation, if it is provided at all, is only a byproduct of the focusing process (closed-loop controller). A line-scan camera traditionally has a single row of pixel sensors, instead of a matrix of them. The lines are continuously fed to a computer that joins them to each other and makes an image. This is most commonly done by connecting the camera output to a frame grabber which resides in a PCI slot of an industrial computer. The frame grabber acts to buffer the image and sometimes provide some processing before delivering to the computer software for processing. Multiple rows of sensors may be used to make colored images, or to increase sensitivity by TDI (Time delay and integration). Many industrial applications require a wide field of view. Traditionally maintaining consistent light over large 2D areas is quite difficult. With a line scan camera all that is necessary is to provide even illumination across the “line” currently being viewed by the camera. This makes possible sharp pictures of objects that pass the camera at high speed. Such cameras are also commonly used to make photo finishes, to determine the winner when multiple competitors cross the finishing line at nearly the same time. They can also be used as industrial instruments for analyzing fast processes. Linescan cameras are also extensively used in imaging from satellites (see push broom scanner). In this case the row of sensors is perpendicular to the direction of satellite motion. Linescan cameras are widely used in scanners. In this case, the camera moves horizntally. Further information: Rotating line camera Stand alone cameras can be used as remote camera. One kind weighs 2.31 ounces, with a periscope shape, IPx7 water-resistance and dust-resistance rating and can be enhanced to IPx8 by using a cap. They have no viewfinder or LCD. Lens is a 146 degree wide angle or standard lens, with fixed focus. It can have a microphone and speaker, And it can take photos and video. As a remote camera, a phone app using Android or iOS is needed to send live video, change settings, take photos, or use time lapse. Many devices have a built-in digital camera, including, for example, smartphones, mobile phones, PDAs and laptop computers. Built-in cameras generally store the images in the JPEG file format. Mobile phones incorporating digital cameras were introduced in Japan in 2001 by J-Phone. In 2003 camera phones outsold stand-alone digital cameras, and in 2006 they outsold film and digital stand-alone cameras. Five billion camera phones were sold in five years, and by 2007 more than half of the installed base of all mobile phones were camera phones. Sales of separate cameras peaked in 2008. Sale of smartphones compared to digital cameras 2009-2013 Sales of traditional digital cameras have declined due to the increasing use of smartphones for casual photography, which also enable easier manipulation and sharing of photos through the use of apps and web-based services. "Bridge cameras", in contrast, have held their ground with functionality that most smartphone cameras lack, such as optical zoom and other advanced features. DSLRs have also lost ground to Mirrorless interchangeable-lens camera (MILC)s offering the same sensor size in a smaller camera. A few expensive ones use a full-frame sensor as DSLR professional cameras. In response to the convenience and flexibility of smartphone cameras, some manufacturers produced "smart" digital cameras that combine features of traditional cameras with those of a smartphone. In 2012, Nikon and Samsung released the Coolpix S800c and Galaxy Camera, the first two digital cameras to run the Android operating system. Since this software platform is used in many smartphones, they can integrate with services (such as e-mail attachments, social networks and photo sharing sites) as smartphones do, and use other Android-compatible software as well. In an inversion, some phone makers have introduced smartphones with cameras designed to resemble traditional digital cameras. Nokia released the 808 PureView and Lumia 1020 in 2012 and 2013; the two devices respectively run the Symbian and Windows Phone operating systems, and both include a 41-megapixel camera (along with a camera grip attachment for the latter). Similarly, Samsung introduced the Galaxy S4 Zoom, having a 16-megapixel camera and 10x optical zoom, combining traits from the Galaxy S4 Mini with the Galaxy Camera. Furthermore, Panasonic Lumic DMC-CM1 is an Android KitKat 4.4 smartphone with 20MP, 1" sensor, the largest sensor for a smartphone ever, with Leica fixed lens equivalent of 28mm at F2.8, can take RAW image and 4K video, has 21mm thickness. Light-field cameras were introduced in 2013 with one consumer product and several professional ones. After a big dip of sales in 2012, consumer digital camera sales declined again in 2013 by 36 percent. In 2011, compact digital cameras sold 10 million per month. In 2013, sales fell to about 4 million per month. DSLR and MILC sales also declined in 2013 by 10–15% after almost ten years of double digit growth. Worldwide unit sales of digital cameras is continuously declining from 148 million in 2011 to 58 million in 2015 and tends to decrease more in the following years. Film camera sold got the peak at 36.671 million units in 1997 and digital camera sold began in 1999. In 2008, film camera market was dead and digital camera sold got the peak by 121.463 million units in 2010. In 2002, cell phone with camera has been introduced and in 2003 the cell phone with camera sold 80 million units per year. In 2011 the cell phone with camera sold hundreds of millions per year, when digital camera sold initialized to decline. In 2015, digital camera sold is 35.395 million units or only less than a third of digital camera sold number in a peak and also slightly less than film camera sold number in a peak. Many digital cameras can connect directly to a computer to transfer data:- A common alternative is the use of a card reader which may be capable of reading several types of storage media, as well as high speed transfer of data to the computer. Use of a card reader also avoids draining the camera battery during the download process. An external card reader allows convenient direct access to the images on a collection of storage media. But if only one storage card is in use, moving it back and forth between the camera and the reader can be inconvenient. Many computers have a card reader built in, at least for SD cards. Many modern cameras support the PictBridge standard, which allows them to send data directly to a PictBridge-capable computer printer without the need for a computer. Wireless connectivity can also provide for printing photos without a cable connection. An instant-print camera, is a digital camera with a built-in printer. This confers a similar functionality as an instant camera which uses instant film to quickly generate a physical photograph. Such non-digital cameras were popularized by Polaroid in 1972. Many digital cameras include a video output port. Usually sVideo, it sends a standard-definition video signal to a television, allowing the user to show one picture at a time. Buttons or menus on the camera allow the user to select the photo, advance from one to another, or automatically send a "slide show" to the TV. HDMI has been adopted by many high-end digital camera makers, to show photos in their high-resolution quality on an HDTV. In January 2008, Silicon Image announced a new technology for sending video from mobile devices to a television in digital form. MHL sends pictures as a video stream, up to 1080p resolution, and is compatible with HDMI. Some DVD recorders and television sets can read memory cards used in cameras; alternatively several types of flash card readers have TV output capability. Cameras can be equipped with a varying amount of environmental sealing to provide protection against splashing water, moisture (humidity and fog), dust and sand, or complete waterproofness to a certain depth and for a certain duration. The latter is one of the approaches to allow underwater photography, the other approach being the use of waterproof housings. Many waterproof digital cameras are also shockproof and resistant to low temperatures. Many digital cameras have preset modes for different applications. Within the constraints of correct exposure various parameters can be changed, including exposure, aperture, focusing, light metering, white balance, and equivalent sensitivity. For example, a portrait might use a wider aperture to render the background out of focus, and would seek out and focus on a human face rather than other image content. A CompactFlash (CF) card, one of many media types used to store digital photographs Many camera phones and most stand alone digital cameras store image data in flash memory cards or other removable media. Most stand-alone cameras use SD format, while a few use CompactFlash or other types. In January 2012, a faster XQD card format was announced. In early 2014, some high end cameras have two hot-swapable memory slots. Photographers can swap one of the memory card with camera-on. Each memory slot can accept either Compact Flash or SD Card. All new Sony cameras also have two memory slots, one for its Memory Stick and one for SD Card, but not hot-swapable. A few cameras used other removable storage such as Microdrives (very small hard disk drives), CD single (185 MB), and 3.5" floppy disks. Other unusual formats include: Most manufacturers of digital cameras do not provide drivers and software to allow their cameras to work with Linux or other free software. Still, many cameras use the standard USB storage protocol, and are thus easily usable. Other cameras are supported by the gPhoto project. Main article: Image file formats The Joint Photography Experts Group standard (JPEG) is the most common file format for storing image data. Other file types include Tagged Image File Format (TIFF) and various Raw image formats. Many cameras, especially high-end ones, support a raw image format. A raw image is the unprocessed set of pixel data directly from the camera's sensor, often saved in a proprietary format. Adobe Systems has released the DNG format, a royalty-free raw image format used by at least 10 camera manufacturers. Raw files initially had to be processed in specialized image editing programs, but over time many mainstream editing programs, such as Google's Picasa, have added support for raw images. Rendering to standard images from raw sensor data allows more flexibility in making major adjustments without losing image quality or retaking the picture. Formats for movies are AVI, DV, MPEG, MOV (often containing motion JPEG), WMV, and ASF (basically the same as WMV). Recent formats include MP4, which is based on the QuickTime format and uses newer compression algorithms to allow longer recording times in the same space. Other formats that are used in cameras (but not for pictures) are the Design Rule for Camera Format (DCF), an ISO specification, used in almost all camera since 1998, which defines an internal file structure and naming. Also used is the Digital Print Order Format (DPOF), which dictates what order images are to be printed in and how many copies. The DCF 1998 defines a logical file system with 8.3 filenames and makes the usage of either FAT12, FAT16, FAT32 or exFAT mandatory for its physical layer in order to maximize platform interoperability. Most cameras include Exif data that provides metadata about the picture. Exif data may include aperture, exposure time, focal length, date and time taken, and location. Digital cameras have become smaller over time, resulting in an ongoing need to develop a battery small enough to fit in the camera and yet able to power it for a reasonable length of time. Digital cameras utilize either proprietary or standard consumer batteries. As of March 2014[update], most cameras use proprietary lithium-ion batteries while some use standard AA batteries or primarily use a proprietary Lithium-ion rechargeable battery pack but have an optional AA battery holder available. The most common class of battery used in digital cameras is proprietary battery formats. These are built to a manufacturer's custom specifications. Almost all proprietary batteries are lithium-ion. In addition to being available from the OEM, aftermarket replacement batteries are commonly available for most camera models. Main article: Commercial off-the-shelf Digital cameras that utilize off-the-shelf batteries are typically designed to be able to use both single-use disposable and rechargeable batteries, but not with both types in use at the same time. The most common off-the-shelf battery size used is AA. CR2, CR-V3 batteries, and AAA batteries are also used in some cameras. The CR2 and CR-V3 batteries are lithium based, intended for a single use. Rechargeable RCR-V3 lithium-ion batteries are also available as an alternative to non-rechargeable CR-V3 batteries. Some battery grips for DSLRs come with a separate holder to accommodate AA cells as an external power source. Digital single-lens reflex camera When digital cameras became common, many photographers asked whether their film cameras could be converted to digital. The answer was yes and no. For the majority of 35 mm film cameras the answer is no, the reworking and cost would be too great, especially as lenses have been evolving as well as cameras. For most a conversion to digital, to give enough space for the electronics and allow a liquid crystal display to preview, would require removing the back of the camera and replacing it with a custom built digital unit. Many early professional SLR cameras, such as the Kodak DCS series, were developed from 35 mm film cameras. The technology of the time, however, meant that rather than being digital "backs" the bodies of these cameras were mounted on large, bulky digital units, often bigger than the camera portion itself. These were factory built cameras, however, not aftermarket conversions. A notable exception is the Nikon E2 and Nikon E3, using additional optics to convert the 35mm format to a 2/3 CCD-sensor. A few 35 mm cameras have had digital camera backs made by their manufacturer, Leica being a notable example. Medium format and large format cameras (those using film stock greater than 35 mm), have a low unit production, and typical digital backs for them cost over $10,000. These cameras also tend to be highly modular, with handgrips, film backs, winders, and lenses available separately to fit various needs. The very large sensor these backs use leads to enormous image sizes. For example, Phase One's P45 39 MP image back creates a single TIFF image of size up to 224.6 MB, and even greater pixel counts are available. Medium format digitals such as this are geared more towards studio and portrait photography than their smaller DSLR counterparts; the ISO speed in particular tends to have a maximum of 400, versus 6400 for some DSLR cameras. (Canon EOS-1D Mark IV and Nikon D3S have ISO 12800 plus Hi-3 ISO 102400 with the Canon EOS-1Dx's ISO of 204800) Main article: digital camera back In the industrial and high-end professional photography market, some camera systems use modular (removable) image sensors. For example, some medium format SLR cameras, such as the Mamiya 645D series, allow installation of either a digital camera back or a traditional photographic film back. Linear array cameras are also called scan backs. Most earlier digital camera backs used linear array sensors, moving vertically to digitize the image. Many of them only capture grayscale images. The relatively long exposure times, in the range of seconds or even minutes generally limit scan backs to studio applications, where all aspects of the photographic scene are under the photographer's control. Some other camera backs use CCD arrays similar to typical cameras. These are called single-shot backs. Since it is much easier to manufacture a high-quality linear CCD array with only thousands of pixels than a CCD matrix with millions, very high resolution linear CCD camera backs were available much earlier than their CCD matrix counterparts. For example, you could buy an (albeit expensive) camera back with over 7,000 pixel horizontal resolution in the mid-1990s. However, as of 2004[update], it is still difficult to buy a comparable CCD matrix camera of the same resolution. Rotating line cameras, with about 10,000 color pixels in its sensor line, are able, as of 2005[update], to capture about 120,000 lines during one full 360 degree rotation, thereby creating a single digital image of 1,200 Megapixels. Most modern digital camera backs use CCD or CMOS matrix sensors. The matrix sensor captures the entire image frame at once, instead of incrementing scanning the frame area through the prolonged exposure. For example, Phase One produces a 39 million pixel digital camera back with a 49.1 x 36.8 mm CCD in 2008. This CCD array is a little smaller than a frame of 120 film and much larger than a 35 mm frame (36 x 24 mm). In comparison, consumer digital cameras use arrays ranging from 36 x 24 mm (full frame on high end consumer DSLRs) to 1.28 x 0.96 mm (on camera phones) CMOS sensor.
