About:
dcraw is a command-line utility for decoding raw image data from a wide range of digital cameras. It extracts the uncompressed sensor data and converts it to standard formats like PPM or TIFF. Its primary value is enabling photographers to access and process RAW files, even from discontinued or obscure camera models.

Key Features:

Supports over 700 camera models from various manufacturers
Performs demosaicing, white balance, and color space conversion
Outputs to standard formats like PPM, TIFF, or FITS for scientific use
Runs on the command line, making it scriptable and lightweight

Use Cases:

Processing RAW files from cameras that are no longer supported by manufacturer software
Batch converting RAW images to a standard format for archival or editing
Extracting uncompressed sensor data for scientific image analysis

Alternatives:

libraw – A more modern C++ library that is based on dcraw but offers more features and active development.
darktable – A full-featured open-source photography workflow application with a GUI, which uses libraw for RAW import.
