Raw files are named so because they are not yet processed and therefore are not ready to be or edited with a. Normally, the image is processed by a raw converter in a wide- internal where precise adjustments can be made before to a 'positive' file format such as or for storage, printing, or further manipulation.
This often encodes the image in a device-dependent color space. There are dozens, if not hundreds, of raw formats in use by different models of digital equipment (like cameras or film scanners). Contents • • • • • • • • • • • • • • • • • • • • • • • • Rationale [ ] Raw image files are sometimes called digital negatives, as they fulfill the same role as in film photography: that is, the negative is not directly usable as an image, but has all of the information needed to create an image. Likewise, the process of converting a raw image file into a viewable format is sometimes called developing a raw image, by analogy with the process used to convert into viewable prints.
The selection of the final choice of image rendering is part of the process of and. Like a photographic negative, a raw digital image may have a wider or color than the eventual final image format, and it preserves most of the information of the captured image.
The purpose of raw image formats is to save, with minimum loss of information, data obtained from the sensor, and the conditions surrounding the capturing of the image (the ). Raw image formats are intended to capture as closely as possible (i.e. At the best of the specific sensor's performance) the characteristics of the scene, that is, physical information about the light intensity and color of the scene. Most raw image file formats store information sensed according to the geometry of the sensor's individual photo-receptive elements (sometimes called pixels) rather than points in the expected final image: sensors with hexagonal element displacement, for example, record information for each of their hexagonally-displaced cells, which a decoding software will eventually transform into the rectangular geometry during 'digital developing'.
File contents [ ] Raw files contain the information required to produce a viewable image from the camera's sensor data. The structure of raw files often follows a common pattern: • A short file header which typically contains an indicator of the of the file, a file identifier and an offset into the main file data • Camera sensor which is required to interpret the sensor image data, including the size of the sensor, the attributes of the and its • Image which is required for inclusion in any environment. 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 data in format. • An image • Most raw files contain a full size JPEG conversion of the image, which is used to preview the file on the camera's LCD panel. Modify File Creation Date.
• In the case of motion picture film scans, either the, or frame number in the which represents the frame sequence in a scanned reel. This item allows the file to be ordered in a (without relying on its filename). • The sensor image data Many raw file formats, including IIQ (), 3FR (), DCR, K25, KDC (), CRW CR2 CR3 (), ERF (), MEF (), MOS (), NEF (), (), PEF (), RW2 () and ARW, SRF, SR2 (), are based on the TIFF file format. These files may deviate from the TIFF standard in a number of ways, including the use of a non-standard file header, the inclusion of additional image tags and the encryption of some of the tagged data. Panasonic's raw converter corrects geometric distortion and on such cameras as the, with necessary correction information presumably included in the raw.

The same holds for Canon's DPP application, at least for all more expensive cameras like all and the of compact cameras., the Adobe digital negative format, is an extension of the TIFF 6.0 format and is compatible with, and uses various and/or, including,,,,, and. Sensor image data [ ] In, the raw file plays the role that plays in. Raw files thus contain the full resolution (typically 12- or 14-bit) data as read out from each of the camera's. The camera's sensor is almost invariably overlaid with a (CFA), usually a, consisting of a mosaic of a 2x2 matrix of red, green, blue and (second) green filters.
One variation on the Bayer filter is the of the, which exchanged the green in the RG rows with ' (a or color). Other sensors, such as the, capture information directly in RGB form (using three pixel sensors in each location).
These RGB raw data still need to be processed to make an image file, because the raw RGB values correspond to the responses of the sensors, not to a standard color space like.

And sensors are typically straight narrow RGB or RGBI (where 'I' stands for the additional infra-red channel for automatic dust removal) strips that are swept across an image. The is able to store the infrared raw data, which can be used for, as an additional 16-bit channel. The remainder of the discussion about raw files applies to them as well. (Some scanners do not allow the host system access to the raw data at all, as a speed compromise.
The raw data are processed very rapidly inside the scanner to select out the best part of the available dynamic range so only the result is passed to the computer for permanent storage, reducing the amount of data transferred and therefore the bandwidth requirement for any given speed of image throughput.) To obtain an image from a raw file, this mosaic of data must be converted into standard RGB form. This is often referred to as 'raw development'. When converting from the four-sensor 2x2 Bayer-matrix raw form into RGB pixels, the green pair is used to control the luminance detail of the processed output pixel, while the red and blue, which each have half as many samples, are used mostly for the more slowly-varying component of the image. If raw format data is available, it can be used in conversion, as a simpler alternative to the multi-exposure HDI approach of capturing three separate images, one underexposed, one correct and one overexposed, and 'overlaying' one on top of the other. Standardization [ ] Providing a detailed and concise description of the content of raw files is highly problematic. There is no single raw format; formats can be similar or radically different.
Different manufacturers use their own proprietary and typically undocumented formats, which are collectively known as raw format. Often they also change the format from one camera model to the next. Several major camera manufacturers, including Nikon, Canon and Sony, portions of the file in an attempt to prevent third-party tools from accessing them. This industry-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 software which decodes raw image formats, particularly, has helped to alleviate these concerns. An essay by and Juergen Specht stated 'here are two solutions – the adoption by the camera industry of A: Public documentation of RAW [sic] formats; past, present and future, or, more likely B: Adoption of a universal RAW [sic] format'.
