How to get better Levels preview? H/S clipping warning overlay?

[Daniel Geiger]

I use quite a few layers in my images. To adjust levels of individual portions, I have to group those (occasionally also in second level groups). The histogram in levels is a very poor representation of the brightness distribution (see image). How can I get that more meaningful?

It seems that layer order matters, which is really weird. The lower layers have poorer (flatter) histograms than the upper ones. Not 100% sure that holds all the time.

 

Second, AP retains all the information of each image part (which is actually good), even if it is outside the current canvass, or is hidden behind another layer. Is there a way to get histogram for just the visible part of each layer? The footer of each of these images is pure white, so when I try to adjust white point, it is difficult to know where the white of the image is, rather than the invisible footer of the files.

 

Some sort of highlight/shadows clipping warning (with color overlay on affected area?) would be very helpful. If it exists, I have not found it yet. Gamut warning does not work for me.

 

Thanks!

For the histogram levels for just the visible part of each layer, could you not use a rectangular marquee selection & check the Marquee & Layer boxes in the Histogram panel?
