[RFC] Equivalent GEGL filters for PSD Adjustment Layers

Hi all! I’m working to implement importing PSD Adjustment Layers in GIMP. I’ve got 6 implemented now (see example), with 2 - 3 remaining easy ones.

Some adjustment layers won’t be available until we can support Descriptor attributes (hopefully in 3.4). But others could be implemented if I knew which GEGL filter(s) to match with. You can see the full list on the issue report.

I was hoping someone here might have some ideas. The ones that would be “easy” if I knew a matching filter are:

  • Photo Filter
  • Vibrance (Saturation filter works for saturation setting, but I’m not sure about the vibrance setting)
  • Exposure (Settings seem a bit different than GIMP’s version of the filter)
  • Selective Color

Any help is appreciated!
