NotMyFault Posted January 6, 2022 Share Posted January 6, 2022 Affinity Photo is limited to 8 bit per channel when rendering 16-bit documents. Tested both on Windows and Mac This leads to unexpected banding. The only option to view images in more than 8 bit depth is to convert into RGB/32. This is quite unfortunate. If Affinity rates this as "by design", could you move it to the feedback section? AP 1.10.4.1098.

kirk23 Posted January 10, 2022 Share Posted January 10, 2022 I'm more concerned with not what Affinity shows on your screen but rather what it saves to files. And it saves every gradient with noisy dithering, in 32 bit mode too . Sometimes it's not ok at all. Especially when you work with depth channel.

True, but this has been addressed in separate reports (forced dithering of gradients in all color modes, workaround: group + layer fx overlay at 0% opacity trick). We should try to keep these topics separate. kirk23 1 Quote Mac mini M1 A2348 | Windows 10 - AMD Ryzen 9 5900x - 32 GB RAM - Nvidia GTX 1080 LG34WK950U-W, calibrated to DCI-P3 with LG Calibration Studio / Spider 5 iPad Air Gen 5 (2022) A2589 Special interest into procedural texture filter, edit alpha channel, RGB/16 and RGB/32 color formats, stacking, finding root causes for misbehaving files, finding creative solutions for unsolvable tasks, finding bugs in Apps.
