Problem with Level Adjustment

[Pablo89]

Hi there!

Ive got strange problem with Level Adjustment.
I wanna change highlights 255 to 254 So after click OK it goes back to 255 Why?
It never happend to me this before ive changed 255 to 254 many times and worked but now something goes wrong but i am not sure what?

Why i wanted changed highlights 255 to 254?
Because im working on 3D modeling and texture with 255 had black spots on white. but ive change to 254 black spots are gone.

Hello and welcome to PSG.

Are you referring to a Levels Adjustment? (IMAGE > ADJUSTMENTS > LEVELS) This is a one time adjustment that always starts at 0 to 255.........no matter what you've done before.

Are you using a Levels Adjustment layer? (LAYER > NEW ADJUSTMENT LAYER > LEVELS) Which is different in that you can go back and make changes to it. The adjustment will be exactly where you left it if and when you return to it.
