Type of format	Prototype file formats

A camera raw prototype file contains minimally processed data from the image sensor of either a digital camera, a flick film scanner, or other image scanner.^{[ane] [2]} Raw files are named so because they are non yet processed and therefore are non set to be printed or edited with a bitmap graphics editor. Commonly, the image is candy by a raw converter in a wide-gamut internal colour space where precise adjustments can be made earlier conversion to a "positive" file format such equally TIFF or JPEG for storage, printing, or farther manipulation. There are dozens of raw formats in use by different manufacturers of digital epitome capture equipment.

Rationale [edit]

Raw image files are sometimes incorrectly described as "digital negatives", but neither are they negatives nor do the unprocessed files found visible images. Rather, the Raw datasets are more than like exposed merely undeveloped moving picture which can exist converted (electronically developed) in a not-destructive mode multiple times in appreciable, reversible steps to reach a visually desired prototype. (With exposed motion picture, development is a single upshot that physically transforms the unexposed film irreversibly.)

Like undeveloped photographic film, a raw digital paradigm may take a wider dynamic range or color gamut than the developed motion picture or impress. Unlike physical picture later on development, the Raw file preserves the information captured at the time of exposure. The purpose of raw image formats is to relieve, with minimum loss of information, data obtained from the sensor.

Raw image formats are intended to capture the radiometric characteristics of the scene, that is, physical information about the light intensity and color of the scene, at the best of the camera sensor's operation. Most raw image file formats store information sensed according to the geometry of the sensor's individual photo-receptive elements (sometimes chosen pixels) rather than points in the expected final paradigm: sensors with hexagonal element displacement, for example, record data for each of their hexagonally-displaced cells, which a decoding software volition eventually transform into the rectangular geometry during "digital developing".

File contents [edit]

Raw files contain the information required to produce a viewable prototype from the camera's sensor data. The construction of raw files ofttimes follows a mutual pattern:

• A short file header which typically contains an indicator of the byte-ordering of the file, a file identifier and an commencement into the master file data
• Camera sensor metadata which is required to translate the sensor image information, including the size of the sensor, the attributes of the CFA and its color profile
• Image metadata which tin can be useful for inclusion in any CMS environment or database. These include the exposure settings, camera/scanner/lens model, date (and, optionally, place) of shoot/scan, authoring information and other. Some raw files contain a standardized metadata section with information in Exif format.
• An image thumbnail
• Most raw files contain a total size JPEG conversion of the paradigm, which is used to preview the file on the camera's LCD panel.
• In the instance of motion-picture show film scans, either the timecode, keycode or frame number in the file sequence which represents the frame sequence in a scanned reel. This item allows the file to be ordered in a frame sequence (without relying on its filename).
• The sensor image information

Many raw file formats, including IIQ (Phase 1), 3FR (Hasselblad), DCR, K25, KDC (Kodak), CRW CR2 CR3 (Canon), ERF (Epson), MEF (Mamiya), MOS (Leaf), NEF NRW (Nikon), ORF (Olympus), PEF (Pentax), RW2 (Panasonic) and ARW, SRF, SR2 (Sony), are based on TIFF, the Tagged Image File Format.^[three] These files may deviate from the TIFF standard in a number of means, including the apply of a non-standard file header, the inclusion of additional image tags and the encryption of some of the tagged information.

Panasonic's raw converter corrects geometric distortion and chromatic abnormality on such cameras as the LX3,^{[4] [5] [six]} with necessary correction information presumably included in the raw.^[7] Phase One'southward raw converter Capture One as well offers corrections for geometrical distortion, chromatic aberration, imperial fringing and keystone correction emulating the shift capability of tilt-shift in software and specially designed hardware, on nigh raw files from over 100 different cameras.^{[viii] [9]} The same holds for Catechism'southward DPP awarding, at to the lowest degree for all more expensive cameras like all EOS DSLRs and the G series of compact cameras.

DNG, the Adobe digital negative format, is an extension of the TIFF 6.0 format and is uniform with TIFF/EP, and uses various open up formats and/or standards, including Exif metadata, XMP metadata, IPTC metadata, CIE XYZ coordinates, ICC profiles, and JPEG.^[10]

Sensor image data [edit]

In digital photography, the raw file plays the role that photographic picture plays in film photography. Raw files thus contain the full resolution (typically 12- or fourteen-scrap) data equally read out from each of the camera's paradigm sensor pixels.

The photographic camera's sensor is most invariably overlaid with a color filter array (CFA), commonly a Bayer filter, consisting of a mosaic of a 2x2 matrix of red, greenish, blue and (2nd) green filters.

One variation on the Bayer filter is the RGBE filter of the Sony Cyber-shot DSC-F828, which exchanged the greenish in the RG rows with "emerald"^[11] (a blue-green^[12] or cyan^[13] color). Other sensors, such equally the Foveon X3 sensor, capture data directly in RGB form (using three pixel sensors in each location). This RGB raw data still needs to exist candy to make an image file, considering the raw RGB values correspond to the responses of the sensors, non to a standard colour space like sRGB. As in that location is no color filter array, there is no need for demosaicing.

Flatbed and film scanner sensors are typically straight narrow RGB or RGBI (where "I" stands for the additional infrared channel for automated dust removal) strips that are swept beyond an image. The HDRi raw data format is able to store the infrared raw information, which can be used for infrared cleaning, as an additional 16-chip channel. The residual of the word almost raw files applies to them too. Some scanners do not permit the host system admission to the raw data at all, every bit a speed compromise. The raw data are candy very rapidly inside the scanner to select out the best part of the available dynamic range so simply the consequence is passed to the figurer for permanent storage, reducing the amount of data transferred and therefore the bandwidth requirement for any given speed of prototype throughput.^{[ citation needed ]}

To obtain an paradigm from a raw file, this mosaic of data must be converted into standard RGB form. This is often referred to as "raw evolution".

When converting from the iv-sensor 2x2 Bayer-matrix raw form into RGB pixels, the light-green pair is used to control the luminance detail of the processed output pixel, while the red and bluish, which each have half every bit many samples, are used mostly for the more slowly-varying chroma component of the image.

If raw format data is available, it can be used in loftier-dynamic-range imaging conversion, as a simpler alternative to the multi-exposure HDI arroyo of capturing three separate images, one underexposed, i correct and i overexposed, and "overlaying" ane on height of the other.

Standardization [edit]

Providing a detailed and concise description of the content of raw files is highly problematic. There is no single raw format; formats tin be similar or radically different. Dissimilar manufacturers use their ain proprietary and typically undocumented formats, which are collectively known equally raw format. Ofttimes they also change the format from i camera model to the next. Several major photographic camera manufacturers, including Nikon, Canon and Sony, encrypt portions of the file in an try to prevent 3rd-party tools from accessing them.^[14]

This manufacture-wide situation of inconsistent formatting has concerned many photographers who worry that their valuable raw photos may someday become inaccessible, as computer operating systems and software programs become obsolete and abandoned raw formats are dropped from new software. The availability of high-quality open up source software which decodes raw epitome formats, specially dcraw, has helped to alleviate these concerns. An essay by Michael Reichmann and Juergen Specht stated "here are ii solutions – the adoption past the camera industry of A: Public documentation of RAW [sic] formats; past, present and hereafter, or, more than likely B: Adoption of a universal RAW [sic] format".^{[15] [xvi] [17]} "Planning for [United states] Library of Congress Collections" identifies raw-file formats as "less desirable file formats", and identifies DNG as a suggested culling.^[18]

DNG is the only raw image format for which industry-wide buy-in is beingness sought. It is based upon, and compatible with, the ISO standard raw epitome format ISO 12234-2, TIFF/EP, and is existence used by ISO in their revision of that standard.

The ISO standard raw image format is ISO 12234-2, amend known every bit TIFF/EP. (TIFF/EP too supports "non-raw", or "processed", images). TIFF/EP provided a footing for the raw image formats of a number of cameras. For instance, Nikon's NEF raw files are based on TIFF/EP, and include a tag which identifies the version of TIFF/EP they are based on.^[19] Adobe's DNG raw file format was based on TIFF/EP, and the DNG specification states "DNG ... is uniform with the TIFF-EP standard".^[20] Several cameras utilise DNG as their raw image format, so in that limited sense they utilize TIFF/EP too.^[21]

Adobe Systems launched this DNG raw image format in September 2004. By September 2006, several camera manufacturers had started to denote support for DNG in newer camera models, including Leica, Samsung, Ricoh, Pentax, Hasselblad (native camera support); and, Better Light (export).^[22] The Leica Digital-Modul-R (DMR) was commencement to use DNG as its native format.^[23] In September 2009 Adobe stated that in that location were no known intellectual property encumbrances or license requirements for DNG.^[24] At that place is a "Digital Negative (DNG) Specification Patent License",^[25] simply it does non actually state that there are any patents held on DNG, and the September 2009 statement was fabricated at to the lowest degree 4 years after this license was published.

TIFF/EP began its v-yr revision cycle in 2006.^[26] Adobe offered the DNG specification to ISO to be part of ISO's revised TIFF/EP standard.^{[27] [28]} A progress report in Oct 2008 from ISO about the revision of TIFF/EP stated that the revision "... currently includes two "interoperability-profiles," "IP i" for candy image data, using ".TIF" extension, and "IP 2" for "raw" image information, ".DNG" extension".^[29] It is "IP 2" that is relevant here. A progress report in September 2009 states that "This format will be similar to DNG 1.3, which serves as the starting point for development."^[xxx]

DNG has been used by open-source developers.^[14] Apply by camera makers varies: the largest companies such as Canon, Nikon, Sony, and some others, practice not use DNG. Smaller companies and makers of "niche" cameras who might otherwise have difficulty getting support from software companies oft utilize DNG as their native raw image format. Pentax uses DNG as an optional culling to their ain raw image format. There are fifteen or more such companies, even including a few that specialize in pic cameras.^[21] In add-on, nearly Canon point & shoot cameras tin can support DNG by using CHDK.

Canon Raw v2 (CR2) is mostly based on TIFF ^[31] and lossless Jpeg ITU-T81.^[32]

Catechism Raw v3 (CR3)^[33] is based on ISO Base Media File Format (ISO/IEC 14496-12), with custom tags, and unknown "crx" codec.

Processing [edit]

To be viewed or printed, the output from a camera'due south image sensor has to be processed, that is, converted to a photographic rendering of the scene, and then stored in a standard raster graphics format such every bit JPEG. This processing, whether done in-camera or later in a raw-file converter, involves a number of operations, typically including:^{[34] [35]}

• decoding – image data of raw files are typically encoded for pinch purpose, but as well often for obfuscation purpose (e.grand. raw files from Canon^[36] or Nikon cameras).^[37]
• demosaicing – interpolating the fractional raw data received from the color-filtered image sensor into a matrix of colored pixels.
• defective pixel removal – replacing data in known bad locations with interpolations from nearby locations
• white balancing – accounting for color temperature of the low-cal that was used to take the photograph
• noise reduction – trading off detail for smoothness past removing small fluctuations
• color translation – converting from the camera native color space defined by the spectral sensitivities of the image sensor to an output colour infinite (typically sRGB for JPEG)
• tone reproduction^{[38] [39]} – the scene luminance captured past the camera sensors and stored in the raw file (with a dynamic range of typically x or more than bits) needs to be rendered for pleasing upshot and right viewing on depression-dynamic-range monitors or prints; the tone-reproduction rendering often includes separate tone mapping and gamma compression steps.
• compression – for instance JPEG compression

Demosaicing is merely performed for CFA sensors; it is non required for 3CCD or Foveon X3 sensors.

Cameras and image processing software may also perform boosted processing to meliorate image quality, for example:

• removal of systematic noise – bias frame subtraction and apartment-field correction
• dark frame subtraction
• optical correction – lens distortion, vignetting, chromatic aberration and color fringing correction
• contrast manipulation
• increasing visual vigil by unsharp masking
• dynamic range compression – lighten shadow regions without blowing out highlight regions

The raw file (left) before highlight and shadow details were recovered using the levels tool (right)

When a camera saves a raw file it defers well-nigh of this processing; typically the only processing performed is the removal of defective pixels (the DNG specification requires that lacking pixels exist removed earlier creating the file^[40]). Some camera manufacturers do additional processing before saving raw files; for example, Nikon has been criticized by astrophotographers for applying noise reduction earlier saving the raw file.^[41]

Some raw formats also allow nonlinear quantization.^{[42] [43]} This nonlinearity allows the pinch of the raw information without visible deposition of the image by removing invisible and irrelevant information from the image. Although noise is discarded this has nothing to do with (visible) noise reduction.^{[ citation needed ]}

Benefits [edit]

Nearly all digital cameras tin can process the image from the sensor into a JPEG file using settings for white balance, color saturation, dissimilarity, and sharpness that are either selected automatically or entered by the photographer before taking the movie. Cameras that produce raw files save these settings in the file, only defer the processing. This results in an extra step for the lensman, and so raw is normally only used when boosted computer processing is intended. All the same, raw has numerous advantages over JPEG such as:

• Many more shades of colors compared to JPEG files - raw files have 12 or fourteen bits of intensity information per channel (4096-16384 shades), compared to JPEG's gamma-compressed eight bits (256 shades).
• Higher image quality. Because all the calculations (such as applying gamma correction, demosaicing, white balance, brightness, contrast, etc...) used to generate pixel values (in RGB format for most images) are performed in one step on the base of operations data, the resultant pixel values will be more authentic and exhibit less posterization.
• Bypassing of undesired steps in the camera'southward processing, including sharpening and noise reduction
• JPEG images are typically saved using a lossy pinch format (though a lossless JPEG compression is at present bachelor). Raw formats typically use lossless pinch or loftier-quality lossy pinch.
• Finer command. Raw conversion software allows users to dispense more than parameters (such every bit lightness, white remainder, hue, saturation, etc...) and do so with greater variability. For example, the white signal can be set to any value, non just detached preset values like "daylight" or "incandescent". Furthermore, the user can typically run into a preview while adjusting these parameters.
• The colour infinite tin be ready to whatsoever is desired.
• Different demosaicing algorithms can be used, non merely the ane coded into the camera.
• The contents of raw files include more information, and potentially college quality, than the converted results, in which the rendering parameters are fixed, the color gamut is clipped, and there may exist quantization and compression artifacts.
• Big transformations of the data, such equally increasing the exposure of a dramatically under-exposed photograph, consequence in fewer visible artifacts when done from raw information than when washed from already rendered paradigm files. Raw information leave more telescopic for both corrections and artistic manipulations, without resulting in images with visible flaws such as posterization.
• All the changes made on a raw prototype file are non-subversive; that is, only the metadata that controls the rendering is inverse to make unlike output versions, leaving the original information unchanged.
• To some extent, raw-format photography eliminates the need to use the HDRI technique, assuasive a much improve control over the mapping of the scene intensity range into the output tonal range, compared to the process of automatically mapping to JPEG or other viii-bit representation.

Drawbacks [edit]

• Camera raw file size is typically ii–6 times larger than JPEG file size.^[44] While use of raw formats avoids the pinch artifacts inherent in JPEG, fewer images can fit on a given retention card. However, the large sizes and low prices of modern memory cards mitigate this. Burst mode shooting tends to be slower and shorter due to the larger file size.
• Virtually raw formats implement lossless data compression to reduce the size of the files without affecting prototype quality. Just some others utilize lossy data compression where quantization and filtering is performed on the image data.^{[42] [43]} Sony'south lossy 11+7 bit delta compression of raw information causes posterization nether certain weather condition.^[45] Several Nikon cameras let photographers choose between no compression, lossless pinch or lossy compression for their raw images. Red Digital Cinema Camera Company introduced .r3d Redcode Raw with compression ratio from 3:1 to 18:1 which depends on resolution and frame rates.^[46]
• The standard raw image format (ISO 12234-2, TIFF/EP) is non widely accepted. DNG, the potential candidate for a new standard format, has not been adopted by many major photographic camera companies. (See "Standardization" section). Numerous different raw formats are currently in employ and new raw formats keep appearing, while others are abandoned.^[47]
• Considering of the lack of widespread adoption of a standard raw format, more specialized software may exist required to open raw files than for standardized formats like JPEG or TIFF. Software developers have to frequently update their products to back up the raw formats of the latest cameras but open source implementations like dcraw brand it easier.
• The time taken in the image workflow is an important factor when choosing betwixt raw and ready-to-employ prototype formats. With modern photo editing software the boosted time needed to process raw images has been greatly reduced merely it withal requires an actress footstep in workflow in comparison with using out-of-photographic camera JPEGs.

Software support [edit]

Cameras that back up raw files typically come with proprietary software for conversion of their raw image data into standard RGB images. Other processing and conversion programs and plugins are available from vendors that take either licensed the technology from the camera manufacturer or reverse-engineered the particular raw format and provided their ain processing algorithms.

Operating arrangement support [edit]

Apple tree macOS and iOS [edit]

In Jan 2005, Apple released iPhoto 5, which offered bones support for viewing and editing many raw file formats.

In Apr 2005, Apple tree's OS Ten ten.four brought raw support to the operating system's ImageIO framework, enabling raw back up automatically in the majority of macOS applications both from Apple tree (such as Preview, macOS's PDF and image viewing application, and Discontinuity, a photo mail service-production software package for professionals) as well as all third party applications which make use of the ImageIO frameworks.

Semi-regular updates to macOS generally include updated support for new raw formats introduced in the intervening months by camera manufacturers.

In 2016, Apple announced that iOS 10 would allow capturing raw images on selected hardware, and third party applications volition be able to edit raw images through the operating organization'south Cadre Epitome framework.^[48]

In 2020, Apple released the iPhone 12 Pro and iPhone 12 Pro Max. Both of these devices support Apple tree ProRAW (equally of iOS xiv.3). ProRAW photos are 12 bit DNG files.

Microsoft Windows [edit]

Windows Camera Codec Pack [edit]

Microsoft supplies the free Windows Photographic camera Codec Pack for Windows XP and later on versions of Microsoft Windows, to integrate raw file viewing and printing into some Microsoft Windows tools.^[49] The codecs allow native viewing of raw files from a variety of specific cameras in Windows Explorer / File Explorer and Windows Live Photo Gallery / Windows Photo Gallery, in Windows Vista and Windows 7.^[l] As of October 2016, Microsoft had not released an updated version since Apr 2014, which supported some specific cameras by the post-obit manufacturers: Canon, Casio, Epson, Fujifilm, Kodak, Konica Minolta, Leica, Nikon, Olympus, Panasonic, Pentax,Samsung, and Sony. For windows 10 this was essentially replaced in 2019 past Microsoft Raw Image Extension.^[l]

Raw Epitome Extension [edit]

Microsoft as of 2019 supplies the free Raw Prototype Extension for Windows 10 and later versions of Microsoft Windows, to integrate raw file viewing and press into some Microsoft Windows tools. ^[51] The Extension allows native viewing of raw files from many mid- to high-end digital cameras in Windows Explorer / File Explorer and Microsoft Photos.

Windows Imaging Component (WIC) [edit]

Microsoft Windows supports the Windows Imaging Component (WIC) codec standard. WIC was available as a stand-alone downloadable program for Windows XP Service Pack two, and built into Windows XP Service Pack 3, Windows Vista, and afterward versions. Windows Explorer / File Explorer, and Windows Live Photo Gallery / Windows Photo Gallery can view raw formats for which the necessary WIC codecs are installed. Canon, Nikon, Sony, Olympus and Pentax have released WIC codecs for their cameras, although some manufactures only provide codec back up for the 32-chip versions of Microsoft Windows.^[52]

Commercial DNG WIC codecs are also available from Ardfry Imaging,^[53] and others; and FastPictureViewer Professional installs a prepare of WIC-enabled paradigm decoders.^{[54] [55]}

Raw bitmap files [edit]

Less commonly, raw may also refer to a generic image file format containing simply pixel color values. For example, "Photoshop Raw" files (.raw) contain viii-bits-per-aqueduct RGB data in summit-to-bottom, left-to-correct pixel order. Dimensions must be input manually when such files are re-opened, or a foursquare epitome is causeless. Due to its simplicity, this format is very open and uniform, though limited past its lack of metadata and run-length encoding. Especially in photography and graphic pattern, where colour direction and extended gamuts are important, and big images are mutual.
