Step 1: FIND A PICTURE!
This Instructable uses Adobe Photoshop. I used version CS5 for this tutorial but most versions should work similarly. The first step is finding the perfect photograph!! It doesn't matter if you are using a photograph of yourself or of a friend, or even a celebrity, there are just a few rules that make the process easier...
1) Photos that are "straight on" views are easier that faces at an angle.
2) Faces with no teeth showing work best.
3) Higher resolution pictures turn out better than low resolution pictures.
Once you've picked out your picture, you are ready to start!
