I decided to try out photoshop and mess around with it a little. Found a pretty good tutorial too. Just a question though: when they say "2000x2000, 330ppi" in the tutorials (for when you make the new file) I assume they mean 2000x2000 pixels, 330 pixels per inch? Because it's defaulted to centimeters for my photoshop and if I go 2000x2000 centimeters with 330ppi it gives me a file size of 150gig... which is just a little much!
