I saw a tutorial on TV. The tutorial was like this:
Take your snap sitting on chair, another standing on left side of chair and then last one standing on the right side of the chair. Now, use Photoshop to merge these three pics. After everything it will be three look alike on the pic.
Now, I want to search this tutorial on web but I don't know what to write for "How to create __ in Photoshop"? Please suggest.
Edit I tried body double and doppelgänger but it is not the word I am looking for.
