Raw Therapee 3 Is Now Free Software

Posted by kdawson on from the eye-altering-alters-all dept.

kantier writes "The only (as far as I know) usable and free (as in beer) program for processing RAW photos outside Windows or OS X is now also free as in freedom. From version 3 onwards, the code is licensed under the GPL v3. The main developer's reasons for opening up the program are a lack of time/resources for full dedication, and a lack of interest in some parts of the program (likes to fiddle with image-processing algorithms, not so much the GUI part) — so the F/OSS model seems to be a perfect fit for this project."

  1. Re:dcraw is used by almost all raw converters by tlhIngan · · Score: 5, Interesting

    Adobe Camera Raw, as well as most of the other commercial software which decodes raw images, used dcraw source and probably still uses much of that code. The license for dcraw permits it, and Dave Coffin is pretty proud of that. He should be- his code is used worldwide by millions of photographers.

    No big surprise - dcraw has reverse-engineered *every* RAW file format out there, and new cameras are being added pretty quickly. (The dirty little secret of RAW files is many manufacturers make RAW file formats proprietary so there's no generic RAW file opener. That is, until dcraw came around. Hopefully things will change with the digital negative format (DNF) format which is a standardized RAW file format).

    If you want to open a RAW file, dcraw will understand it. He's got a right to be proud of it. Imagine trying to create a workflow if you have a bunch of different equipment and RAW files, and have to use Nikon's tool for once, Canon's for another, Sony's for a third, etc...
