Visualization paper

Hi everyone. As the resident painter in the class, my Visualization paper is about contemporary art and the use of Photoshop. I am writing a longer paper because I hope to submit it to a few journals. So I don't think I will have it completely done by tomorrow, though it is getting quite long. The artists I am focusing on mainly are Cory Arcangel and Julie Mehretu.  David Hockney and Kevin Appel's work will also be mentioned to a lesser degree. I was wondering if the class had any insight on other artists that could be mentioned to compare or contrast? They do not have to necessarily present their work digitally but they do have to maybe illustrate or demonstate something to do with Photoshop. For example, I'm using an article about Leonardo's presentation drawings to support some of my research. I know our class thinks very out of the box so I hope someone can give me insight for a new angle!
