@elle, I found the problem with the colorspace tool; the profile wasn’t being updated for the display, so the previous profile was being used against the converted image. That, and a few other things, are fixed and in a 0.6.2pre AppImage posted in the 0.6.1 release page:
Note to others, this AppImage has a library removed, libharfbuzz, that Gentoo didn’t like. It should work okay with Debian/Ubuntu distros, YMMV for others.
So, there are two approaches to do color management in rawproc. Both require the following settings in Properties:
Option #1: dcraw profiles
input.raw.libraw.colorspace=prophoto, or one of the other dcraw options
input.raw.libraw.gamma=prophoto, or one of the other corresponding gamma presets
This will allow opening a raw file with the image converted from the adobe coeff, to the dcraw output profile and TRC applied. That’ll then be the working profile for the rest of the processing chain.
Option #2: Proper Working Space Profile
This at open will assign yourcameraprofile.icc to the unconverted raw linear image, then input.raw.default contains tools to apply when a raw file is opened, and here a colorspace tool is specified with a working profile and ‘convert’ for the operation. When the open and default processing is done, the image is available for further work in the working colorspace.
To your original challenge, getting a TIFF with the camera profile assigned would be:
Open the raw, then save as a TIFF.
