These videos will help you to become a true master at Adobe Photoshop! There are 10 in all and they cover everything including: Layers, Tools, Curves, Masks, etc.
Not only that, but if you order soon enough, I will even give you a link to download Adobe Photoshop CS6 while it is still in beta! But you have to hurry!
Their beta period has ended, but you can still get a 30-day trial.
