Hi Dan C
I have tried to develop the mentioned picture in Darktable 3.0, then in Luminar 4, Zoner Photo Studio X and at the end in Affinity Photo. The results from these editors I enclosed to this email.
Crop from jpg Zoner Photo Studio
Crop from jpg DarkTable 3.0
Crop from jpg Luminar 4.1.
Crop from Affinity Photo after developing from RAW file (crop from window of Affinity Photo)
I have no idea, how to remove magenta from the bridge. Yes, this is not jpg. In previous photo editors I can play with saturation exposure. But I could not find the solution for this in tools of Affinity Photo. My operation system is Windows 10. Primary I develop RAW files from my photos and I am looking to find effective way to do it. I have learned some theories about color spaces, human eyes, photosensors, transform of colors. Maybe there is effective way to do it in Affinity Photo but as I wrote I don't know how.
