Dear Serif Team and Affinity Photo users, I'm a VFX Compositor & Matte Painter and I'd like to move from PS to AP. I hope you can help me with some questions regarding the Implementation and proper use of ACES and 32-bit. My background plate is exported from Nuke as an ACES - ACES2065-1 16-bit EXR file. The import into AP (22.214.171.124) works fine - the file get's recognized as an ACES file and I get the same result using OCIO. But there are a few things I can't get my head around yet: How do I pick and paint high color values? Using the exposure slider in the 32-bit Preview I see that there are high values. If I pick and paint them back in, the result is way darker. (Changing the exposure doesn't effect the false picked color) picked in Nuke for comparison I moved from PS because there is a 16Bit limitation and I had to work with ACEScc files (log encoded) and use an ICC profile to check my work. I hoped to get around this using AP. Those threads are dealing with the same issue but the information is contradictory and I can't reproduce the method quoted first. https://forum.affinity.serif.com/index.php?/topic/49815-hdr-raw-pixel-values/ https://forum.affinity.serif.com/index.php?/topic/19787--/ What is the proper workflow of importing and edit JPGs in an ACES setup in AP? Unfortunately there's no way of assigning an IDT during import (as in Nuke) but I can reproduce Nukes behavior with OCIO Adjustment Layers, which seams pretty inconvenient. (Windows Photo Viewer as comparison) Bottom left: Two OCIO nodes in sequence [ACES2056-1 to Utility - Curve - sRGB] followed by [Output - sRGB to ACEScg]. Bottom right: Two OCIO nodes in sequence [ACES2056-1 to Utility - Curve - sRGB] followed by [Utility - sRGB - Texture to ACEScg]. This post deals with the question of the right IDT for JPGs in general. I guess going the Utility - sRGB - Texture way is better, isn't it? My color settings: If you need further information or I haven't made my questions clear enough please don't hesitate to ask. I'm glad about any help or further learning resources! Thanks a lot
