I have used Photoshop quite a bit to fix up the pictures of the presidents. The tools I use for that are the crop tool, the unsharp mask, and a High Pass Stylize tool. It makes the pictures look less blurry and sharpens them up a lot. I WAS using Illustrator until I accidentally deleted all of my files when I had just finished a big chunk of my project. I’m going to have to start over completely.
