Are there any fuller instructions around on how to extract the target image correctly for use with dcamprof.If I extract it from the raw linear TIFF using Photoshop, for example, is Photoshop going to apply a profile (unless I say it should be unmanaged)?I would use RawTherapee, as suggested, but the interface is fairly non-standard. Before I dive into the manual, is there a quick recipe for getting it to do the necessary, if that is preferable to using DCRaw?[...] Thanks.

Thanks. Yes, it does, but it seems costly for the limited task that I would use it for.
for a limited task the trial shall work ....
Thanks. I'll give it a go. Looking at the instructions on your site, I see that you recommend output gamma of 1.8. Is that right for dcamprof?
not exactly... if you are looking to compensate C1 'transfer function' more precisely then you can extract it from .tiff and then apply it according to your profile building workflow... alternatively you certainly can use gamma around ~1.8* (tastewise, may be you like something between 1.7* and 1.9*)... your call... but 'transfer function' != gammathat is if you are talking about C1 raw converter of course

The scanin tool find that my pattern match is not good enough, so I'm a bit stuck.
I had no idea BOX had a monthly BW cap. Will have to examine alternatives.
Thanks but I try to avoid most Google products these days.
The shot orientation looks perfectly okay. Maybe there's something wrong with the colors is the converted file? I note in the log output that the input file is only 8 bits, it should be 16 bit if you converted in any of the ways suggested in the docs.I assume you're making a file for DCP? It should look greenish, like this:http://www.ludd.ltu.se/~torger/photography/camera-profiling.html#step4The easiest way to do it with free tools is using RawTherapee (as you can crop/rotate there), described here:http://50.87.144.65/~rt/w/index.php?title=Color_Management#Save_Reference_Image_for_ProfilingIf you're going to use the profile in Adobe Lightroom it's safest to first make a DNG via Adobe DNG Converter and make the reference image from that, as raw decoding might differ. If you don't have a too exotic camera it shouldn't differ though and you could use the native raw also in RawTherapee/DCRaw.
