Well, this is exactly what I was trying to describe a process for in my last mail, but I may not have done it very well. The general idea being to use a good selection of images (preferably including a good target shot or two with a light trap and specular white at near clipping) to find something like a "least common denominator" preset; one which isn't intended to be ideal for any particular image, but is most of the way there for images *typical* of the ones you're concerned with. Also discussed is the addition of an extra, expendable "knee" curve if desired to get somewhere between the relative "flatness" of filmic RGB and the often overdone "punch" of camera processing. There is obviously no "one size fits all" solution; the interesting question for me is how to "have your cake and eat it too"... it doesn't seem like setting up a default rendering which you like (whatever that might mean - no need to debate taste here) should require discarding filmic RGB altogether, even if you aren't completely aligned with its entire philosophy. The fact that filmic RGB is an excellent way to *make further adjustments* is reason enough to try to integrate it, IMHO. -- jys ____________________________________________________________________________ darktable user mailing list to unsubscribe send a mail to [email protected]
