I was just about to finish a new work for GR, but iam having a problem at the end:
I am trying to make this into a brush: http://img694.imageshack.us/img694/2241/94715006.jpg
but when I do this: Edit->Define brush preset,
It says: http://img42.imageshack.us/img42/8259/77410993.jpg
It doesnt make any sense o_O
nvm guys i figured out what the problem was, you probably cant define white~grey brushes 
colour mode problem?
It’s the blur. PS can’t find “whole pixels”.
I dont need help anymore, as I said – the problem solved.
