I have been experimenting with a photo editing technique called "Out of Bounds". It enables you to give your photos a 3D look by having the subject "step" out of the frame. I found a great tutorial created by Serrator in the Flickr community -- "OOB Tutorial". The tutorial does a great job of walking the the user through step by step instructions on how to create OOB photos using Adobe Photoshop.
Lots of fun. Here is my initial attempt at an OOB photo.
