yep, actually its very simple
my scanner is 300 dpi
1st when u have scanned your artwork its dull and has a low contrast
then u can adjust it in 'windows live photo gallery' (click fix @ the top) you can either choose adjust
exposure or auto adjust, but i prefer adjust exposure where u can adjust it manually so ur artwork would look the same as the original 1 (・∀・@)
n thx!! feel free to ask me anything
