sgrotehans Posted February 29, 2024 Posted February 29, 2024 Hi, opening a HIF Photo from my Nikon Z8 give only very low contrast image. I use Affinity Photo 2.4 on macOS Sonoma. To get sufficient results I need to adjust white level (from 100% to 65%) and gamma (from 1 to 1.5). Affinity Photo describes the picture as RGBA/32 - SRGB IEC61966-2.1 (Linear) . However it is only RGB/10 and I guess its log (not linear). I assume a bug in Affinity Photo here while importing the 10Bit RGB HLG HIF file. It looks the color profile is wrong interpreted. In contrast opening the same picture with Gimp (after importing I get: Convert to RGB Working Space? From BT.2020 to GIMP build-in sRGB.) I get a correct result. Additionally in the build in preview of MacOS is see also a correct representation of the HIF file. Is this a known bug? Or miss I something? Addition: Same result on my iPad with AP 2.4
