Lovely shot, just a tad overexposed and that causes the main issues. In RawTherapee most of the purple fringing on the mask can be removed by simply turning on the Defringe tool. Though some sort of weird halo remains. I don’t think the effects of the fringing can be completely undone…
For what it’s worth, this is my take with rather simple edits. This is done in the development version of RawTherapee and loading the pp3 in 5.8 may give slightly different results.
Working from @Thanatomanic pp3 all fringes in the mask are now gone (mostly), but some saturation in reds is lost. And I haven’t able to completely remove the remaining purple tint around the eyes:
If you have access to darktable, set input color profile to linear Rec709 RGB.
As I see this, it is a question about saturation & proper color profile.
I have a similar dilemma with our neighbour’s hedge, having the most electric red leaves I have ever seen. I have tested an X-trans camera, an old Canon EOS – but the **** leaves still are too electric. Is it because of my monitor? Is it because of my development habits? No. It’s because I have not yet learnt how to treat color profiles properly. Grumpf.
This helps me understand a little more of what I’m seeing, thank you. I saw as people have pointed out it’s really only his face and hand that are over exposed, but somehow I was thinking the problem with the red jacket was the same. You’d think with as many threads as I’ve read recently about a project to assemble devices for creating hyper accurate input color profiles, the light bulb would have flickered when I saw what was happening, but I needed a hint.
Thank you all for your very quick and helpful responses. When I can get back to my computer, I’ll start examining your examples.
I’ve also tried Filmulator, simply with the defaults and with +2/3 EV added (I prefer my pictures brighter). Every time I fire it up, it’s just magic. This is a really amazing piece of software!
In the first one I used a lut I made a while ago but I made this edit in Darktable, it’s pretty much the same thing (if only a bit magenta but it was a very fast edit):
I’ve tried loading the history into darktable from the JPG I downloaded, but it just gives me the default history stack.
But then exiftool -a -u -g1 -ee -api RequestAll=3 *embed*jpg showed that it’s actually an ART image; I didn’t know ART would also embed the history, so made the wrong assumption.
