I would like to point two unrelated things out:
- The word “raw” is a plain word. It is not an acronym or an initialism. As such, the usual noun capitalization rules apply. Writing RAW is incorrect. If starting a sentence, capitalize the first letter, leave the other two in lowercase. If in the middle of a sentence, all letters should be lowercase.
- The unstable RawTherapee-3.1 builds require LittleCMS version 2. Ubuntu users should see the guide in the forum on how to install LCMS2 in Ubuntu. RawTherapee-3.0 builds require LittleCMS version 1.
