Like brightness/contrast, the color adjustement filter is taking advantage to the new curve widget of krita, allowing finer adjustement to each color. For the following image, I have used the filter to reproduce the color of an old picture.
Note, that applying the oposite curve allow to restore the original color :
Excellent.I understand that the easiest way to color balance a digital photo is to photograph an 18 percent gray card (Google for that phrase) in the same scene, then adjust the color of the picture to bring it back to the same reference. I couldn’t figure out how to do this in Fireworks. Does Krita make this possible, or easy?BTW, “adjustment” and “opposite”
I guess it might be possible, but krita does nothing to make it easy. And I don’t have a 18 percent gray card to test it.But I suppose that using curve you might be able to adjust the color until you get the good color for the card.
