Original dcraw site
Dave Coffin's RAW file decoder
Open source RAW file decoder, able to read and convert X3F files (currently only SD series) too.
My tweaked version (2009/11/30)
Windows 32bit command-line executable, compiled with Microsoft VC 2008 Express
Source code of previous, based on Dave Coffins source revision 1.431, dated 2009/09/22.
Some errors noticed already :)
* Original code branch (without -q 4 option) doesn't produce correct results, use original dcraw ouput to compare (fixed 2009/11/30)
* Borders, affected by CA in normally exposed low-ISO image could show artefacts - green and magenta dots (fixed 2009/11/30)
* Gamut recovery mode makes reds go dark and somewhat magenta (instead of recovering them) (not fixed)
Recommended command line options
To activate new X3F file handling, two options can be used:
-q 4 interpolate using floating point arithmetic (slow, but much better results for higher ISO files) -G 1 attempt gamut recovery for color-shifted red and yellows, parameter is in range 0.5-4.0, 1.0 is recommended
Usual command line for producing 16bit tiff file in sRGB space, using new options, would be about:
dcraw -6 -T -q 4 -G 1 -o 1 -g 2.4 12.92 SDIM1234.X3F
