Archived discussion. This page is a verbatim copy of a thread from

until it was taken offline in June 2025 after the site was compromised — a counterfeit
site had been planted inside the forum software, so the whole thing had to come down.
The original address was https://community.ansel.photos/view-discussion/lighttable-srgb-images-issue-with-adobergb.
No crawler ever captured this particular thread, so the text below — taken straight from the forum database — is the only copy left.
Answers may refer to older versions of Ansel, and image attachments did not survive the shutdown. Current discussion happens on GitHub Discussions .

Hi,
I’m using Ansel on Windows 10 and my monitor profile is generated by calibration software: color space is AdobeRGB.
In Lighttable module, jpeg images with embedded sRGB color profile look strongly oversaturated instead color reproduction is fine in Darkroom and Slideshow modules. Images with embedded AdobeRGB color profile are always correct.
In attachment two jpg images I’ve generated with Gimp to quickly detect visualization issues. The former has sRGB embedded color space, the latter has AdobeRGB: the leftmost two patches should look very similar in both images.

Hi again,
I’ve noticed that the issue happens when images have not yet been processed. For example, enabling exposure module in Darkroom (zero adjustment) fixes the issue in Lighttable.

Images that have not been processed display the JPEG thumnail embedded in the RAW file, which more likely are sRGB. Your issue would indicate that those JPEGs get slapped to display, in lighttable, without color management. Once you edit the files, the default thumbnail gets replaced by Ansel preview, which supports color management.
