Gimp v2.10.28 gamma is perfect, Pass my test. this modification to give more space to darker values does lead to wonky color maths when mixing the colors. We can see this with the following experiment: Left: Colored circles blurred in a regular sRGB space. Right: Colored circles blurred in a linear space. Colored circles, half blurred. In a gamma-corrected environment, this gives an odd black border. In a linear environment, this gives us a nice gradation. This also counts for color smudge brush: That’s right, the ‘muddying’ of colors as is a common complaint by digital painters everywhere, is in fact, a gamma-corrected colorspace mucking up your colors. If you had been working in LAB to avoid this, be sure to try out a linear rgb color space.

Go to Edit -> Color Settings... (Ctrl+Shift+K) and klick on the More Options button. In the Advanded Controls rollout at the bottom there is an option called Blend RGB Colors Using Gamma: activate this option and set it to 1.00, now Photoshop will do linear maths on all the colours even.

NotMyFault Posted October 13, 2021 Share Posted October 13, 2021 As a limited workaround, you can adjust blend gamma on layer level. create a new layer for every color, to keep it separate set blend ranges, blend gamma to 1 (from 2.2) This does not intend to weaken your feature request, i fully support it.

Frozen Death Knight Posted April 22, 2022 Share Posted April 22, 2022 @AftemplateI agree that there should be easy ways to customise these. Like a presets system where you choose your own default Blend Options whenever you make a new layer/group/whatever. One trick I have found though is that you can actually select multiple layers at the same time and drag the value down to 1 so you don't have to manually change one at a time. Might be a good thing to know. 2022-04-22 23-30-15.mp4 Quote Link to comment Share on other sites More sharing options...
cgidesign Posted April 28, 2022 Share Posted April 28, 2022 please give us gamma 1 for blending even without the need to trick around with layers. Bazyzzy 1 Quote Link to comment Share on other sites More sharing options...

Affinity publishes updates when there are ready (a few times per year), and normally won't give any updates on status of bug fixes or feature requests (except in rare cases).
