For an animation a friend and myself were doing in class, we decided to make a rap video, involving everyone who was taking the comtech course this semester. We wanted different heads on different bodies, and orignally we were going to cut and paste using magazines, but quickly decided we could edit all the bodies on photoshop.
All the bodies and heads don't fit together perfectly, and we sort of wanted it that way, for comical value.
Step 1: What programs to use/Materials.
The only thing you'll really need for this, is photoshop, and your imagination!
Open photoshop, then open the photo of your choice.
