Anyone familiar with Photoshop knows that you once you're on an active layer, you either press Ctrl + T or Command + T and you are going to transform that layer. You are then presented with different options like Perspective, Skew, and CW [clock wise] 90 degrees.
You can basically change that layer--make it greater, fit a certain width, or simply mess it up if you really don't know what you're doing. Do you see where I'm going at now? How Life can be transformed?
I'm becoming cheezy as a Cheeto. But really, watch this video by photographer Zack Arias. It was was originally posted in Scott Kelby's [Photographer, and author of many Photoshop books] blog where he has guest interviews.
