Affinity Photo has a very nice Histogram so far, I can switch between each channel
All, R, G + B
All, C, M, Y + K
All, L, A + B
and I can activate layers and selections optional which is totally great! Thanks for that feature.
But I think a luminance channel or option is needed in RGB and CMYK too, for minimum of two reasons:
- I could only see and use the white and black tone spreading over the whole image
- I could work without colors (incl. greyscaled icons) which confusing the eyes at work
