Hi,
When I save my RAW image to jpeg, the resulting jpeg has incorrect colors.
To show what i mean, I have included screen shots of the finished RAW image in ART and the Jpeg image in Irfan view.
Is there an issue as to how I should be saving my images?
I never encountered this discrepancy in RAW Therapee
Thanks
Hi, what color profile are you using for export? Can you share your .arp sidecar?
Thanks!
Maybe check your display profile as well…Irfan likely uses your OS display profile if you have CM enabled ( unless you can set it explicitly, not sure if that viewer lets you specify it) and maybe you are currently set differently in ART so you are not using the same display profile… worth confirming…
Hi Alberto,
Thanks for having a look…

Thanks, I will confirm
Hi, you are exporting in prophoto colour space (in “colour → output profile”). From your screenshot, it seems your image viewer is not applying the ICC profile in the image. You can either export as srgb, or you need to figure out how to make your image viewer use the ICC profile from the image.
HTH
I agree with the profile comments. On my screen, the brown fur has about a +10-degree HSL hue difference between the screenshot and the posted image.
Thanks. I changed the output color profile to sRGB and it now looks the same in Irfan as a jpeg.
Is there a resource available to understand all the color output profiles in ART?
All the profiles work together to help produce the final image… You can of course in the end pick different color profiles for the final output. The main features of a color space used in the chosen profile are the primaries, the gamut, the whitepoint and the transfer function sometimes noted as the gamma of the output with 1 being linear and then other common ones are 1.8 2.2 2.4 or 2.6 … Knowing what you want to do ie generally the destination of your output usually dictates what you use… generally something like srgb for sharing online although maybe over time things are moving towards something like P3, and then if you are doing further processing you might use a linear wide gamut space like prophoto or rec2020 as the source for further processing…that is very very general summary… For things to look right you need to calibrate your display and use the right profiles for your camera…so proper input and display profiles as well… then it can be the wild west outside your own ecosystem as you cant control how others will view your image…you can only send it out with a standard profile embedded so that color managed applications will handle it properly…

are some decent resources for CM and colorspaces and profiles…
I am sure others will have their favourite suggestion…
Maybe this too and some of the other content on her site…
Thank you for your well written reply. Plenty of learning to look forward to.
There is a ton to learn and to try and remember…there are also profile types ie matrix or matrix and luts and there are nuances to those but basically when you output you are just packaging the edited data in a way that is generally taking the wide gamut working space that you did all your editing in and packaging/converting it to a lower gamut for output to a device or medium say for printing. If further processing is going to be done in other software then you will use a profile that preserves that data for editing…
