Because many raw image formats are specific to one make or model of camera, dcraw is frequently updated to support new models. For many proprietary raw image formats, dcraw's source code (based largely on reverse-engineering) is the best—or only—publicly available documentation. dcraw currently supports the raw formats of several hundred ...
Digital Negative (DNG) is an open, lossless raw image format developed by Adobe and used for digital photography.It was launched on September 27, 2004. [1] The launch was accompanied by the first version of the DNG specification, [2] plus various products, including a free-of-charge DNG converter utility.
Free and open-source software portal; 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, [4] and "is intended for embedding in raw converters, data analyzers, and other programs using raw files as the initial data."
This processing, whether done in-camera or later in a raw-file converter, involves a number of operations, typically including: [30] [31] decoding – image data of raw files are typically encoded for compression purpose, but also often for obfuscation purpose (e.g. raw files from Canon [32] or Nikon cameras).

RawTherapee is a free and open source application for processing photographs in raw image formats such as those created by many digital cameras. [5] It comprises a subset of image editing operations specifically aimed at non-destructive post-production of raw photos and is primarily focused on improving a photographer's workflow by facilitating the handling of large numbers of images.
RAW is not a standardized format, in fact, RAW-formats even differ between camera models from the same vendor [citation needed]. Data in a RAW-file is structured according to the Bayer filter's pattern in cameras that use a single image sensor. Debayering, the process of obtaining bitmap data from a RAW-image is always a lossy operation.
