ultrainfra Posted August 12, 2021 Posted August 12, 2021 I have a new 10-bit HDR + Wide Color Gamut monitor. Affinity photo version: 1.10 Windows build: Windows 10 Home 64-bit (10.0, Build 19042) (19041.vb_release.191206-1406) Details of my graphics / monitor configuration: Windows HD Color : On Display Capabilities: Use HDR : Yes , Use WCG: Yes Color Profile: Rec2020 Gamma 2.2 (D65 White Point) Disabling the "Use HDR" option under Windows HD Color settings does allow affinity photo to display SDR content properly, but at the extent of every other application I use which work properly with windows HDR. Affinity is the odd one out here, and nothing in the options/preferences in Affinity Photo seem to allow configuration of display color rendering, only the working space. I have also tried changing my monitor's color profile, and adjusting the relative brightness of SDR content in the Windows HD Color settings. Affinity photo rendering of an SDR image with Windows HDR enabled. Affinity Photo rendering of SDR content with Windows HDR disabled. As rendered by any other app (Darktable, Rawtherapee, GIMP, etc) with Windows HDR enabled SDR content as rendered by other apps with windows HDR disabled To reiterate, colors are rendered most properly in all other apps I have except Affinity with Windows HDR enabled. Affinity only looks proper with it disabled. The relative changes in rendering are invariant with respect to my chosen display profile. So, while I am going to get a colorimeter to fine tune my display profile that will not solve the problem here. Leaving HDR off hence would make for an unappealing look to content as rendered in most other programs, and changing the setting every time I tab over to a different program is kind of a pain. Is there any way to make Affinity behave consistently with my other apps in displaying SDR content with windows HDR enabled? I suspect Affinity just hasn't yet integrated color management of SDR content for HDR mode (at least, in Windows). If the behavior of Affinity shown here is intentional, why has it been designed to render SDR content differently in HDR mode compared to other apps? Quote
Staff DWright Posted August 17, 2021 Staff Posted August 17, 2021 If you assign your monitors ICC profile to the document in Affinity Photo does this improve the colour display range for the SDR image. Quote

No, though since I updated to the recent affinity version the images are now too light. This is regardless of whether or not HDR mode in Windows is enabled or no. In any case, as before I also ensured the HDR-SDR brightness balance was set appropriately in Windows. So, the problem has somewhat changed forms now. Below is a screenshot of the rendering of an 8 bit out of camera JPEG. The image should appear with very dark shadows as it was taken looking into the forest. It seems like affinity might not be color managed, or that the color management isn't working properly. Is Affinity Photo color managed outside of 32 bit mode with "ICC Display Transform" enabled? Affinity Photo - sRGB Affinity Photo -- With Display profile assigned as you suggest. Any other color managed application (this is taken from GIMP, but is identical in darktable or rawtherapee or even the older color managed windows photo viewer) Quote
Pat AFF Posted April 17, 2024 Posted April 17, 2024 (edited) I have the exact same problem, I wonder if anyone has found a solution since the last post dates from 2021 ? Edited April 17, 2024 by Pat AFF Quote
