OpenRAW Badge Square 128 White
OpenRAW was an initiative to raise awareness of a serious problem with top-end digital photography and to help solve that problem. The problem concerns long-term access and viewing of the raw images often used by professional and experienced amateur photographers. OpenRAW's solution (also their motto) was "Digital Image Preservation Through Open Documentation". This initiative was primarily an international (non-political) advocacy and lobby activity directed at companies making digital cameras and those developing software to support those cameras. It also had the aim of raising awareness of the problem among photographers. Its resources included a website with a discussion forum, and many registered supporters, including individuals, companies, and professional organizations. Formation Early in 2005, Juergen Specht and the members of his mailing list D1scussion began to identify concerns about the difficulties associated with the proprietary RAW files introduced by camera m ...

Digital Negative
Digital Negative (DNG) is a patented, open, lossless raw image format developed by Adobe and used for digital photography. Adobe's license allows use without cost on the condition that the licensee prominently displays text saying it is licensed from Adobe in source and documentation, and that the license may be revoked if the licensee brings any patent action against Adobe or its affiliates related to the reading or writing of files that comply with the DNG Specification. It was launched on September 27, 2004. The launch was accompanied by the first version of the DNG specification,. plus various products, including a free-of-charge DNG converter utility. All Adobe photo manipulation software (such as Adobe Photoshop and Adobe Lightroom) released since the launch supports DNG.. DNG is based on the TIFF/EP standard format, and mandates significant use of metadata. Use of the file format is royalty-free; Adobe has published a license allowing anyone to exploit DNG,. and has a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LibRaw
LibRaw is a free and open-source software library for reading raw files from digital cameras. It supports virtually all raw formats. It is based on the source code of dcraw, with modifications, and "is intended for embedding in raw converters, data analyzers, and other programs using raw files as the initial data." LibRaw is available for Windows, macOS, Linux and FreeBSD. It is included in many Linux distributions such as Arch Linux, Debian, Fedora, Gentoo Linux, openSUSE, Slackware and Ubuntu. Software incorporating LibRaw includes digiKam, EasyHDR, gThumb, Gwenview, IrfanView, KStars, OpenImageIO, Siril, and Topaz Studio.

Dcraw
dcraw is an open-source computer program which is able to read numerous raw image format files, typically produced by mid-range and high-end digital cameras. dcraw converts these images into the standard TIFF and PPM image formats. This conversion is sometimes referred to as ''developing'' a raw image (by analogy with the process of film development) since it renders raw image sensor data (a "digital negative") into a viewable form. A number of other image processing programs use dcraw internally to enable them to read raw files. Development of dcraw began on February 23, 1997. Version 1.0 was released in revision 1.18, on May 5, 2000. Versions up to 3.15 used the name ''Canon PowerShot Converter'', starting with v3.40 the name was ''Raw Photo Decoder'', switching to ''Raw Photo Decoder "dcraw"'' in v5.70. Version 8.86 supported 300 cameras. The development has stalled, with only two releases since May 2015 and the last release dated June 2018, but parts of dcraw are incl ...

Image File Formats
An Image file format is a file format for a digital image. There are many formats that can be used, such as JPEG, PNG, and GIF. Most formats up until 2022 were for storing 2D images, not 3D ones. The data stored in an image file format may be compressed or uncompressed. If the data is compressed, it may be done so using lossy compression or lossless compression. For graphic design applications, vector formats are often used. Some image file formats support transparency. Raster formats are for 2D images. A 3D image can be represented within a 2D format, as in a stereogram or autostereogram, but this 3D image will not be a true light field, and thereby may cause the vergence-accommodation conflict. Image files are composed of digital data in one of these formats so that the data can be displayed on a digital (computer) display or printed out using a printer. A common method for displaying digital image information has historically been rasterization. Image file sizes The s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olympus Corporation
is a Japanese manufacturer of optics and reprography products. Olympus was established on 12 October 1919, initially specializing in microscopes and thermometers. Olympus holds roughly a 70-percent share of the global endoscope market, estimated to be worth approximately US$2.5 billion. Its global headquarters are located in Shinjuku, Tokyo, Japan. In 2011, Olympus attracted worldwide media scrutiny when it fired its CEO and the matter snowballed into a corporate corruption investigation with multiple arrests. It paid $646 million in kickback fines in 2016. Products Cameras and audio In 1936, Olympus introduced its first camera, the Semi-Olympus I, fitted with the first Zuiko-branded lens. The Olympus Chrome Six was a series of folding cameras made by Takachiho, and later Olympus, from 1948 to 1956, for 6×4.5 cm or 6×6 cm exposures on 120 film. The first innovative camera series from Olympus was the Pen, launched in 1959. It used a half-frame format, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nikon
(, ; ), also known just as Nikon, is a Japanese multinational corporation headquartered in Tokyo, Japan, specializing in optics and imaging products. The companies held by Nikon form the Nikon Group. Nikon's products include cameras, camera lenses, binoculars, microscopes, ophthalmic lenses, measurement instruments, rifle scopes, spotting scopes, and the steppers used in the photolithography steps of semiconductor fabrication, of which it is the world's second largest manufacturer. The company is the eighth-largest chip equipment maker as reported in 2017. Also, it has diversified into new areas like 3D printing and regenerative medicine to compensate for the shrinking digital camera market. Among Nikon's many notable product lines are Nikkor imaging lenses (for F-mount cameras, large format photography, photographic enlargers, and other applications), the Nikon F-series of 35 mm film SLR cameras, the Nikon D-series of digital SLR cameras, the Nikon Z-series of digital mi ...

Raw Image Format
A camera raw image file contains unprocessed or minimally processed data from the image sensor of either a digital camera, a motion picture film scanner, or other image scanner. Raw files are named so because they are not yet processed and therefore are not ready to be Photographic printing, printed, viewed or edited with a bitmap graphics editor. Normally, the image is processed by a raw converter in a wide-gamut internal color space where precise adjustments can be made before file format conversion, conversion to a viewable file format such as JPEG or PNG for storage, printing, or further manipulation. There are dozens of raw formats in use by different manufacturers of digital image capture equipment. Rationale Raw image files are sometimes incorrectly described as "digital Negative (photography), negatives", but neither are they negatives nor do the unprocessed files constitute visible images. Rather, the Raw datasets are more like Exposure (photography), exposed but Lat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

JPEG
JPEG ( ) is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG typically achieves 10:1 compression with little perceptible loss in image quality. Since its introduction in 1992, JPEG has been the most widely used image compression standard in the world, and the most widely used digital image format, with several billion JPEG images produced every day as of 2015. The term "JPEG" is an acronym for the Joint Photographic Experts Group, which created the standard in 1992. JPEG was largely responsible for the proliferation of digital images and digital photos across the Internet, and later social media. JPEG compression is used in a number of image file formats. JPEG/Exif is the most common image format used by digital cameras and other photographic image capture devices; along with JPEG ...
