Hello, 

 

I'm not sure if it's the right place to this topic, so if it's not - I apologise.

 

Sometimes I want to check on photo what is the pure white and what is pure black, and when I tried to do this in  AP using threshold, I could only check the black parts. When I set 100% value in threshold it shows like there is no white on picture. Should it be that way?

 

Cheers

The Threshold adjustment isn't a checking tool, it's an adjustment: when you use it, you're changing the pixel content of the image (so when you set the value to 100% you aren't showing that there's no white, you're changing the picture to one where there is no white).

If you just want to check on what is pure black or white, use the levels adjustment, set to grays, and move the sliders so that black or white are just 1% apart at either end.
