Photoshop: Minimum AND Maximum sharing one dialog

Report · Feb 12, 2015

Hi there.

Can we have minimum AND maximum filter in the same window ?
I’m not using them enough to assign shortcuts or to memorize if black or white will grow.
Half of the time i pick one for the other and have to close and dig again inside the menus...
I would love it if they were joined.

If they need to stay for actions compatibility, could we have a switch that jumps to the other filter?
Or could the slider go to negative numbers for the opposite behaviour?

It might be more explicit with an image :

The most frustrating moment is when you think you close the wrong filter, think you pick the other one, and pick the same one!

For the unified Min/Max filter, it will be great to add an option to extend/contrast only in the edge (with a threshold and feather sliders) to preserve colors and shades on a non-solid color layer content.

More as an exercise than anything else, however, I hope that somebody finds it useful!

That's an interesting idea!
