I’m still an amateur at Photoshop. I can do quite a few things, but nothing like what you’ll see in the work of Erik Johansson. Check out these highly imaginative images.

And check out this additional innovative project by Johannson – A chance to simulate looking down from the top of a building.
Here’s how Johansson used Photoshop to create this photo. 130 layers are involvedm and a video shows how this was done in fast motion. http://erikjohanssonphoto.com/blog/cut-fold-bts/
