Hmmm, I owe you that information, I tried to find the original here, but couldn’t find it. It is probably a common Kodak film (Ektachrome?), as far as I remember from my father’s talks about photography and films. He was an amateur and we were living in Africa (actually I wasn’t still born at the time of this picture), where the options were certainly scarce, speciailly at that time.
I can’t show you a pp3, because I used a custom version of RT which is still a pre-alpha work in progress, but here’s a video that shows how I did it. Basically, I used the CDL controls to manipulate the R and B channels, looking more at the histogram than at the picture itself. I think it should be possible to use a CDL implementation in darktable and/or photoflow to obtain the same effect (though I didn’t try).
Thanks.
In my case (DT), besides setting up input profile to Adobe RGB (which already gave a boost to colors), what I think really changed the colors was the channel mixer tool and the new color balance. I also used the new filmic but it didn’t add much value, at least in my work flow.
This was done on Darktable 2.5.0 beta version
The site probably doesn’t have a streaming server, but this is only a guess.
