Here's the problem: I have a difficult time seperating the line from the white, if that makes any sense. In other words, I scan in a drawing (usually in greyscale) and I have a black, white, and various shades of grey drawing. For the most part, the line is black and the empty space is white (following me here? Yeah, this is sooo-ooo complicated...). However, there's also a certain amount of grey in the line and empty space too. So I try to get rid of as much as I possibly can (painting over it, whatnot...).
Now, when I actually go to paint, the problem I have is that I can't preserve the black line. Well, no... no, I can preserve it because I'm not an idiot... (yah... layers, aye?) but I can't figure out a good, clean way for me to break the line from the white so that I could, say, put the line above the painted areas. Top layer. Nice and clean.
Does that make any sense at all? And I only have a limited edition of Photoshop, if that makes any difference. But... *pleads and begs* Help with this would be appreciated greatly. Muchly. Mucho muchly...
Ok...
