What's the best values to look for for Levels Adjustment layers?

wwphx Apr 12, 2013 2:41 PM

Obviously, if I'm lucky enough to get a 0/0/0 and 255/255/255 point, I'm gold. But frequently I don't. What I'm wondering is if I have a white point that's 231/217/183 (3x3 sample) and I also have a 228/228/228, which is the better to select as my white point? I've never been confident on whether it's better to get closest high values or highest value in one of the RGB points.

Thanks!

Find whitest point using a temporary threshold adjustment layer; use slider to visually find/see it. Read help file.

Generally speaking you want to make the whitest thing in an image *just* pure white in an image, but that could change depending on the image. You could imagine an evening image (e.g., around sunset) where the brightest things would be orange and should stay at least a little orange.

That's my point. If I don't have a pure white, what's the next best? Highest average values, or highest peak value of one of the RGB values?

You can't make a rule - things canno be that simplified. Do whatever looks best.
