APh V2 trial on Window 10. Nividia GPU is set to 10 bit per channel output. Monitor supports 10 bit per channel. Issue: Images on the display shows banding in smooth gradients. This somtimes is inevitable in 8bit documents but should not be an issue with 16 bit and 32 bit documents. Assumption: Affinity does not support 10 per channel output to the display. I consider this being a bug not a feature request, because working with CG and VFX elements (e.g. 32 bit displacement maps for 3d rendering) requires to be see if such a texture has banding issues or not. As Affinity Photo is mentioned to suport 32 bit editing, the limitation to 8 bit output makes it impossible to know, if the banding is in the image data or just a result of the limited output to the display.

Hi, this has maybe been reported before, I can't find the old post right now. If you have a display capable to display 10 bit (or 12 bit), you clearly want to use this in Photo. Unfortunately, while being capable to crate such documents correctly, the rendering to the display is always limited to 8 bit color depth. Only when you switch to RBG/32 and EDR mode, Photo is able to render more than 8 bit color depth to the display. The screenshots (from M1 Mac mini with 10 bit capable display) shows the issue by comparing Mac Preview and Photo showing the identical test image.Test file: https://raw.githubusercontent.com/jursonovicst/gradient/master/test_sequences/1920x1080/gradient_1920-1080_25-50.png
... not present in Photoshop as it should be (both seen on 30-bit display). So is there 16-bit support in AP2 as advertised, or not? Try youself with greyscale gradient RGB 64/64/64 to RGB 96/96/96 (with the 8-bit sliders) in 16-bit RGB mode.
Hi, I'm sure there's a simple answer for this, but I'm still scratching my head after a lot of research ... I'm using APh to stack astrophotography images - and it does a great job ! But - even though my original FITS are 16 bit RGB, APh opens them as 8 bit RGB. So, the dynamic range is only 256, when it should be 65,536. Maybe I'm missing something obvious ??? Thanks, Gary
