Hi Denis,
I don't get the extended colorprofile thing. My camera is supported bij
rawlib and I'd assume so would darktable that uses rawlib. Is this
darktable specific? Does it need specific dedicated colorprofiles?
Rawtherapee seems to handle the colors correctly, but I believe it uses
dcraw. Still I'd prefere darktable for its workflow and features.
Doing a camera calibration takes time and I currently am in short supply
off. We got twins recently. Is there an easy fix?
Best,
Gert

for it not to lit the target.
