This may sound like a stupid question, but is there a special technique for properly scanning your drawings onto the computer?
Everything I scan seems to have a slight blue-ish tint and looks really grainy no matter how pristine the actual drawing is. Is it a matter of having a good scanner (mine is kinda cheap)? Or should I scan it into a different program (I currently scan them into MS Paint because that program is easy to use)?
Any advice would be very much appreciated!

P.S. When giving me advice, please use simple terms because I'm really stupid when it comes to computer stuff. :P
