RawDigger tools work over the whole raw data in the file as well as over arbitrary rectangular regions and 'point' samples.įastRawViewer is the first and the only dedicated application with the purpose of extremely fast culling and pre-processing of RAW images: i.e. Results can be saved as appropriate in the form of bitmaps and/or CSV and CGATS tables. Currently the main tools RawDigger offers are histograms, statistical analysis of raw data (mean, StdDev, min and max values), raw compression tone curve dump (if present). RawDigger allows to view, study, and analyze raw data as recorded by digital photo- and certain video cameras. The library is also useful for raw data analysis and for the purpose of testing sensors and lenses. demosaicking, color transforms, noise reduction, correction for distortions and aberrations introduced by optics, etc. LibRaw library is meant to address the needs of raw convertor developers, GUI developers, and those interested in implementing and testing their own routines for certain steps of raw conversion workflow, i.e.

We offer consulting services, and currently maintain several projects: free open-source multi-platform LibRaw API library based on dcraw FastRawViewer, a fast RAW images viewer and RawDigger, a program to view and analyze raw image data.

'Compressed' is used by Sony, where this is 'lossy'.

Here is a more detailed view of evolution, and links to implementations: Model SRF, SR2 and ARW 1.0 : 12 bits uncompressedĪRW 2.1 : 12 bits cRAW (11 bits + 7 bits). RAW versions and formats had additional features over time: SRF likely stands for Sony Raw File, SR2 is version 2 of SRF, and ARW means Alpha RAW. SRF appeared in January 2004 (DSC-F828), SR2 in December 2005 (DSC-R1) and ARW in July 2006 with Alpha DSLR-A100.ĪRQ, pixel shifting, appeared in November 2017 (A7R III). This document describes RAW file formats used by Sony cameras, with extensions SRF, SR2, ARW and ARQ, from 2004 to today.Īll formats are based on TIFF format, with Intel (little) endianess ('II' marker).
