Right now, all I use is paint to try and remove as much eraser marks and unwanted lines as I can, but I know there are better programs out there. WHat do you suggest?
I suggest you use Photoshop my friend! Now, it is a 400 dollar program, but try asking as many people you know, see if they have a copy they'd be willing to loan you. I got my copy of PS 7 from my cousin who lives in Texas, very far from me, but we started talking and hey! Friends at school, just ask. If you have no luck there, check out eBay and look for a copy of PS 5 LE. The limited edition isnt very good but it IS much better than paint, and usually goes for about $10-20.
