Black or white mat

What actually do the commands"Remove black or Remove white nat"do?

[firstdefence]

Remove Black Matte and Remove White Matte refer to images you may have cut out of a black or white background and when viewed with a colour underneath you see a small halo of black or white. These filters attempt to remove that halo.

To be honest, learning how to refine a selection will remove the usefulness of such filters, they are generally non configurable one-shot attempts that have unpredictable results. making better selections and maxing out the refining skills will yield much better results.
