APh V2 does not support 10bit display output -> limit usability for 16 bit / 32 bit work

[cgidesign]

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 @cgidesign,

As per my reply in the previous thread, I've now added the details of your report to the issue.

Does GTX 1080 Ti support 10 bit per channel in Affinity Photo? What about RTX 3090?

[cgidesign]

Both support 10bpc. The question is: does Affinity?

Interesting: I found this affinity article regarding hdr capabilities of the apps (version 1.7).

https://affinityspotlight.com/article/biggest-ever-affinity-updates-bring-unrivalled-speed-power-and-extensive-new-features/

... And in a market-first for photo editing and graphic design apps, Affinity Photo and Designer now come with full support for the latest HDR / EDR monitors, including the newly-announced Apple Pro Display XDR. This allows photographers to see new levels of the detail captured in RAW files, while designers can push colour intensity in graphics far further than was possible before.

Using Affinity Photo with an HDR monitor offers a simply stunning experience. It’s amazing the detail and dynamic range the latest SLR cameras capture when shooting in RAW, and Affinity Photo now offers the opportunity to actually see all that depth while editing on an HDR monitor.

But this isn’t just for high-end photography. As more and more graphic content is being consumed on HDR displays, it will start to become important that designers are using an app which can both work in a 32bit colour space and render the results on an HDR monitor. Affinity Designer is the first professional graphic design application to do both. ...

Weird. The tests seem to show that there is no 30 bit output to 10bpc display but the ad says it can even do full HDR? Any news on this?

Hello Support,

any news regarding the issue?

Hello Support,

it is almost three month now and I see the issue in 2.0.4. Can you confirm there is an issue. If yes, are there any plans to fix it?

Another year has passed. Any news about 10 bit per channel in Affinity?
