I normally work on a 8 in x 11 in canvas at 300-600 DPI. How do I make bigger or smaller versions of the same artwork without sacrificing quality? I kinda forgot how to do that. Also which of these is the correct way to change the DPI for making a bigger artwork? I started at 600 DPI. 1) 2) I hope this makes sense. I wanted to make several different versions of artwork so people had more choice to buy what they wanted and could afford.
