Hi Ruymura

Never done this, but i think this is possible with a procedural texture.
Affinity Photo: Procedural Texture Nonlinear Transform Correction

Thank you, it worked!

But I'm disappointed that such a simple action requires so many steps.

 

[Setting gamma to 2.2]

Hello!

I'm processing TIFF files generated by VueScan in RAW mode.

These TIFFs are negatives with gamma set to 1.

After opening, I invert them with "Invert" command, but I cannot set their gamma to 2.2 as the max value in "Levels" dialog is 2.

How do I set gamma to 2.2?
