It’s not perfect, but I’m getting there. I’m trying to utilize the Film Negative feature in RawTherapee 5.9 to convert DSLR/Mirrorless film scans taken in RAW format. Once I get a little further along, I’ll do a tutorial.
i just signed up to tell you: Please do so. This would be very very helpful as there is not much documentation i could find so far.
If you or anyone else could tell me, how black and white negative conversion should work I’d appreciate very much!
A simple approach for B/W negatives is to apply an “upside-down” tone curve in the exposure tool, or the L* curve in L * a * b * Adjustments.
Certain B/W negatives like Ilford XP (chromogenic B/W) tend to have a blue/purple tinge, this can be removed with the Black-and-White tool in the Color tab.
This is a very outdated approach and quite unnecessary for RawTherapee. Just enable the Film Negative module and use that. For some information: Film Negative - RawPedia
Thanks. I’m getting into a video series on a different topic right now, but I might make a break from that to do a Film Negative tutorial.
Sometimes, when Film Negative doesn’t (or can’t) get it quite right, it helps to resort to manual methods. Or at least, a combination of the two.
I think @rom9 would be interested to hear about cases where the tool doesn’t work well.
Sorry for the late reply, and for being away for so long from the forum… unfortunately it’s a complete mess at work, and i have little spare time.
Anyway, @Rick thanks for your interest in the Film Negative module, please share any problem you might encounter, i’ll take a look.
