All source images for the tutorials are supplied to you so you'll be able to do exactly what I did. The tutorials were all done using Photoshop CS5 so CS5 or a newer version is recommended. You can get a lot done with CS3/CS4 also. If you want to try out a more recent version, Adobe offers a Free 30-day trial. Note that if you have Photoshop Elements, you can certainly learn a lot with my tutorials but know that most of the color grading I do is done with options not available in Elements.
