Creating Alternate Versions of Your Photos

Ever wanted to see what your photo looked like as a black and white but then quickly revert to the color version? Or maybe you've adjusted a bunch of settings on your photo, only to realize that you liked the way it looked after just a few changes. Photoshop has a feature called Snapshots that lets you create different versions of your photos so that you can always get back to a certain point without moving all of the sliders to get there.
