Sorry, missed this as I had no internet until yesterday.
I don’t use RTv4-anything. I just download and copy the correctly named icc profiles sRGB profiles into the profiles folder that RT uses.
sRGB_v4_ICC_preference.icc (59.5 KB)
sRGB2014.icc (3.0 KB)
If you watch Raw Therapee Viewers Request - DO THIS FIRST to speed up your Raw Therapee Workflow - YouTube you’ll see what I’m on about.
There are folk on this forum who dislike this operation, but honestly, as a commercial image producer, this process causes me zero problems.
When you export an image that’s tagged with an RTv4 (or v2) colour space, bugger all else can understand it.
RTv4sRGB supposedly maps colours the same as sRGB_v4_ICC_preference.icc, but what ever you view your output images in - say Chrome or Firefox - is expecting a profile instruction header starting sRGB, not RTv4…it’s the RT bit that causes the problem.
There was never any need for this ‘profile renaming’ in RT, and it doesn’t occur in DarkTable.
Anyway, give it a try with the two sRGB profiles I’ve attached, and see if it still causes you a problem.
