You are right Anton, the embeded image "inside" a RAW is generated by camera's internal JPEG(?) engine. Thus any closed-source magic affects the embeded image looks. That is OK, since it is generated there just to have some kind of a fast thumbnail/preview.
However, my problem is related to the difference between DT's 'darkroom' rendering (repsesented decoded RAW data) and somehow weird color profile in *exported* JPEGs. So far it seems there are only KDE/Plasma users. I use GNOME env, so this might be relevant to the way the ICC/profiles are handled. I've found an old thread with the same issue as I have. It seems the guy also used GNOME: http://darktable-users.narkive.com/bcTCeaYG/exported-jpegs-always-darker-and-more-satuated. 2018-05-15 21:15 GMT+02:00 Anton Aylward <[email protected]>: > On 15/05/18 01:57 AM, Yuri wrote: >> Hello, >> it's really frustrating but I can't get any usable export to JPEG. >> >> I got Sony RAWs shot in sRGB, I wanna simply convert them straight to JPEG. >> No >> module tweaking, etc. So I check the image in the 'darkroom' mode - colors >> and >> saturation are perfect there. > > I don't know if it's relevant but ... > > When I view an unprocessed RAW film roll in my file browser it is different > from > the colours/saturation etc I see when I open with DT.
