Hello, and first of all, thanks for helping me!

Affinity (all applications) interprets the screenshots I take as HDR P3 D65, making them look washed out. The problem is that my screen is not HDR, and the profile I use on my screen is Display P3.

When checking the image profile by right-clicking > Get Info on macOS, the image has the correct Display P3 profile.

So, it’s Affinity that is misinterpreting it and changing it to HDR P3 D65 (Linear).

The problem only occurs when the images are in PNG format (which is the default format for macOS screenshots). When changing the format to JPEG, Affinity correctly identifies the Display P3 profile of the image, and they display properly.

Here is a screen shoot of the problem and the (screenshot) that I created for testing.

 

I`m on version 2.5.7 of affinity - on a MAC mini M4 PRO 24gb of ram 512 storage

@eduardotanco Interesting. I'm on a MacBook Pro, M4, 48GB, running Sequoia 15.3 and all my screenshots list "Color LCD" as the embedded PNG profile when viewed using Finder. These images look fine when opened in AfPhoto, which lists the profile as "Display" (which is the profile's Internal name, and is in fact Display P3). I recently updated my OS to 15.3, and I don't recall whether Display P3 was embedded in my previous screenshots, but I didn't see that in some older screenshots I looked at. The monitor on my MBP does have a Display P3 color gamut (compared using ColorSync Utility App). 

I have seen examples where PNG files exported from some other programs mistakenly open as 32-bit linear files in AP, but I've not had any issues with screenshots. 

A workaround until it is fixed is to use a Procedural Texture to convert Linear to 2.2 Gamma, as shown in the formulas below. I saved this as a PT Preset in case it is ever needed, but I haven't had the problem so far.

Hi @Ldina

Thank you for your response,

Yes I have tested it also in my MackBook Pro and as you say it attaches the correct color profile Color LCD that in fact is Display P3 and affinity identifies it correctly and everything works fine. The issue comes when you set the color profile of your screen to Display P3 (Not Color LCD)since I use an external monitor. Then is when affinity open the image as an HDR when is not.

Thank you for the work around! it would help me a lot, I´m currently converting all the images to Jpeg since then it detects the correct color profile, but in case I need PNG this method would be handy.

Hope they can fix this quickly!

Have you tried setting your external monitor to the profile supplied with your monitor, or to a custom created profile using a calibrator? The standard profile should cover the entire gamut of that monitor and I'd think it would be more accurate than using Display P3 (unless it is an Apple display which may use Display P3 profile as standard). It might be worth a try. Maybe something in the Display P3 profile is causing the glitch, because it doesn't happen to me with Color LCD as my monitor profile (on my laptop display, not external).

Just a thought. If you try it, I would be curious to know if that worked.
