Description

I have issues with several images. One of them is attached.

I'm working with Adobe RGB profile monitor profile (DELL U2410 with preset mode "Adobe RGB").

While I've choose Adobe RGB monitor profile, attached file looks more or less ok. It's still ok when exporting to jpg with Adobe RGB profile.
Unfortunately when exporting with sRGB output profile I've got overexposured colour artefacts. The same result when choosing sRGB for monitor colour profile.

I have issues with uploading dng, here it is on my dropbox - it may disappear someday.

#2 Updated by Roman Lebedev about 3 years ago

Hm, are you sure e.g. softproofing is not enabled?
Or gamut check?

#3 Updated by Mikołaj Milej about 3 years ago

both are disabled.
When gammut check is enabled, then there are cyjan coloured markers for (probably) out of gammut. Probably because I'm not very sure if it's properly working.

In my case enabling soft proofing does completely nothing (changing output profile does not change anything). But it's disabled.

#4 Updated by Mikołaj Milej about 3 years ago

I just found out that disabling "always use LittleCMS 2 to applcay output color profile" fixes the issue.
Second thing is that in "lighttable mode" there is no such artefacts.
Does "lighttable mode" respect LittleCMS option?

No, lighttable always uses lcms.
