You will be taking a picture of yourself and manipulating it in Photoshop to create and altered you. Maybe you are going to transform half of your face into a lizard or alien. Below are a few examples of altered faces. I can take a picture of you or you may use Photo-booth. I DO NOT WANT PICTURES OF FAMILY MEMBERS OR FAMOUS PEOPLE. 

Make sure you are using all of the tools in Photoshop and not just cutting an pasting. Don't forget you can use a texture overlay and change the opacity.
