How can I make a white background black?
I have some scanned images that currently have a white background. For presentation purposes, I would like to make the background black. I’ve done this before but can’t remember how and I can’t find my notes on it.
(I’ve been through the FAQ and I’ve searched the forum for an answer but it looks like other posts regarding a black background are more sophisticated or technically based than what I would like to know.)
Thanks in advance!
