This is my first project, which was a Warm and Cool Self Portrait Collage. The process was: Taking a picture of myself with the App Photo Booth, then I open my picture in Adobe Photoshop CS6. Open a new file with a white sheet and then use the the tool select and select the parts of your image that you want then Command C for copy and then Command V for paste in this process you are making Layers which are the pieces that you already select and then you need to change the opacity and color of the part that you select and play with the  colors, filters etc. Then save two copies of your self portrait on the Desktop make a JPEG first which is file save as a copy format JPEG and save the original PSD Photoshop file.
