Earlier @aurelienpierre said “That’s why we need better input profiles than the bogus RGB -> XYZ 3×3 matrice conversion”
and this reminds me I need to ask about these items.
I’ve been using RT a good while and can easily make profiles using my xrite passport and the supplied software (though how good the resulting DCPs are I’m not sure given comments here on pixls over several months).
Recently I’m also using darktable which can use ICC profiles, can’t use DCP ones, but also has built in profiles. However looking here https://github.com/darktable-org/darktable/blob/master/src/common/colormatrices.c (thanks @elstoc for link) my cameras aren’t covered, and in any case if I understand correctly, there are only 12 numbers per camera so this can’t be a very good profile.
So I’m after some good daylight ICC profiles for EOS 6D and 5DSR.
One possibility is that some kind soul may have them to share, perhaps with me providing something in return. If so, please get in touch.
@Morgan_Hardwood , I don’t think RT has a DCP for 5DSR. If I sent some target shots, would you be interested in making a DCP as usual for RT releases, but in addition, an ICC for darktable users?
Part of me thinks I should try to build my own, though looking at dcamprof and argyll, it all seems quite complex with plenty of possible software pitfalls along the way. I could try this under Ubuntu 18.04 or Windows 7. Does anyone have any thoughts on the best route please?
