Softproofing not working

P74 · September 27, 2023, 12:51pm

I am on Mac studio M2 (ventura)
I have all my ICC profiles in home/myname/.config/darktable/color/out
Display profile is on system.
I check everything and anyhow softproof is not working and I don’t find why.
If someone has an idea…

Soft proofing not working with profiled monitor

### Describe the bug Hello! it seems that the soft proofing function is not wor…king, or i am doing something really wrong. When i activate the softproof function, and change the softproof profile from the dropdown, nothing changes in the preview. I have my calibrated display profile, and when softproofing to sRGB nothing changes on the preview, but the exported image is very different. In order to view the image properly as it will be exported, i need to change my display profile and not the softproof profile. I thought merely activating the softproof should display the sRGB image correctly. I have attached various screenshots, on the left is the second preview window of darktable with sRGB display profile and on the right is the preview with softproof on and off sRGB Display profile left, sRGB Display profile right ![Screenshot_20230923_215904](https://github.com/darktable-org/darktable/assets/36011542/80b69ca1-e0b0-4996-a677-a6181478d56e) sRGB Display profile left, System default Display profile right, with softproofactive active ![Screenshot_20230923_215926](https://github.com/darktable-org/darktable/assets/36011542/0bd89140-044d-4849-8677-59432f4e5400) sRGB Display profile left, System default Display profile right, with softproofing inactive ![Screenshot_20230923_215940](https://github.com/darktable-org/darktable/assets/36011542/b1271941-f0ec-4a81-9aff-5dd8537a7d02) You will notice in the screenshot that the image on the left is more saturated and the base of the trunk is darker. ### Steps to reproduce 1) Use a non factory display profile. 2) Edit a raw file to get out of gamut colors 3) Change the softproofing profile while keeping the display profile to the default image and Notice that the preview image is not changing, but the histogram does 4) Change the histogram profile, and notice that the histogram does not change ### Expected behavior change the histogram profile when the histogram profile option is changed, and change the preview colors to reflect the selected softproof profile ### Logfile | Screenshot | Screencast _No response_ ### Commit _No response_ ### Where did you install darktable from? darktable.org ### darktable version darktable 4.4.2 ### What OS are you using? Linux ### What is the version of your OS? Kubuntu 23.04 ### Describe your system? _No response_ ### Are you using OpenCL GPU in darktable? Yes ### If yes, what is the GPU card and driver? gtx 1080ti, 11gb memory , driver version: 525.125.06 ### Please provide additional context if applicable. You can attach files too, but might need to rename to .txt or .zip I also uploaded the raw file with the xmp on google drive in case it aids with the debugging https://drive.google.com/file/d/11H0LEAym1_-tMjGcDVtv9HmPRyq2TUds/view?usp=sharing

Thank you. It’s true histogram is changing but not the preview…
In this case what is the best way for printing and be sure to have the right colors?

Hard to say. I think it has been reported but I have tried a few icc files just to see if it was a consistent thing and enabling softproofing causes DT to crash… I think this has been reported… I will have to confirm that… even if it was functioning I think there is no getting around some test prints to get the settings just right…

Thank you; I don’t print at home but on line so I’ll try to find a solution. I use Darktable since one year and I like the software very much. Have a nice day.
