Blender AgX in darktable (proof of concept)

I left some versions out for testing but tried now the last version. I still think that AgX is the mightiest tonemapper. But anyway I think there is plenty of work to be done regarding UX.

Anyway I’m sure @kofa and the other developers will offer a brilliant tool when the time has come.

My thoughts regarding the ease of use:

  • I preferred the Offset slider with the whitepoint limit.
  • Black and whitepoint settings are working differently from what I would expect.
  • Maybe it would help the user if there would be a graph, showing the curve and how it is treated (like it is in filmic)

By the way a very good image for testing the abilities of the different tone mappers is this:
