Hi here is my workflow:
I use a script, that actually calls dcraw with the following parameters: dcraw -v -T -6 -H 5 -o 4 -g 1.8 0 -q 3 -w -m 5 (make sure you have the newest version of dcraw!) You can find my script here: http://meterprosekun.de/xdcraw/xdcraw It allwos to convert all RAF files in a folder or a single one (first parameter). Nick Payne already posted a script 12/22/2013 on this list. He also explained how to integrate this in a file manager. I call my script from the command line. It requires exiftool and mogrify (from imagemagic). The resulting 16bit tiffs are placed in the folder, from which you call the script. You can also set the value for the highlight recovery as second parameter, which I think can make sense for (heavily) overexposed images. However, in general you can compensate some magenta highlight in dt, changing threshold value in highlight recovery. The basic settings in the script worked fine for most of my images yet. Please note, that my script create the tiffs in ProPhotoRGB color space, because I wanted to avoid any early clipping. However, you have to set this in dt as inpsut color space! (maybe you have to copy the icc into ~/.config/darktable/color/in first) For X-E2 owners: dcraw does only create sRGB output for the X-E2, yet. However, the X100s has the same sensor and is fully supported. So the script creates a temporary copy of the original raw and changes the model with exiftool to Fuji X100s. In any case, after calling dcraw, mogrify compresses the tiff. Finally exiftool is used to copy the original meta data from the rawto the tiff file. Here some warnings are thrown, but I think one can ignore them. You can simply import the tiffs in darktable (I suggest to keep the RAF files in a separate folder). Here you should set the color space and apply a base curve (mine looks like this: http://meterprosekun.de/xdcraw/xe2basecurve.png ). In many cases it makes sens to do some (aggressive) color noise removal to remove color shades: Without color noise removal: http://meterprosekun.de/xdcraw/xdcraw-tut-chromdenoiseoff.png After using non-local means denoise (patch size 1, strength 100%, luma 0, chroma 1oo%): http://meterprosekun.de/xdcraw/xdcraw-tut-chromdenoise.png Alternativly to creating tiffs it might make sense to create openExr files (more precisely convert the tiff into exr). AFAIK openExr providea at least 16 bit per channel as well, but compression is way more efficient. Unfortunately, it seems that openExr cannot store meta data (or at most very few). Hopefully, I could help a little bit ;) Sören Am 19.01.2014 15:06, schrieb H. Mandemaker: > Hello, > I’m new to darktable and to this mailing list, so I’ll probably break a > few rules.
