Has anybody tried this neat, old and probably unknown feature to deal with colour casts?
Image > adjustments > Match color > Neutralize
It does not require a new version of PS. I think it was there even in the days of PS7…
But having been busy scanning my own color film since only a few years ago, I knew nothing about colour casts until recently.
I encourage you to try it.
Back to the reason I’m posting this:
- is there anything that remotely looks like this tool in RawTherapee?
- does anyone have an idea how it actually works?
a. if you do, then please, share your opinion on this, I’d love to be able to replicate its behaviour. (I’m currently looking at the histogram, the vectorscopes, and then playing with temperature and tint)
b. do you know how difficult it would be to add an “auto” shift/stretch option to the RGB curves tool in RT?
(I doubt it’s only R,G,B histogram shifting and stretching at its core; the results it gives are different from the other “auto color”, “auto tone” tools)
Sample “neutralisation” on an obvious case of color cast (car lit by LED lamp posts).
