Here's another photography instructable. Get yourself a camera, download Paint.Net, a free photo editing software, and some single colored structure like a bare wall.

Step 1: take the first pictures
get in front of your wall, as this will act as your green screen. Kind of like a chroma key, it will not show up in the final picture. Take a pose, and have somebody snap a picture. My pose wasn't so great becuase i had to take the picture myself, pressing the shutter with my foot. It isn't advised.
