Adobe Photoshop has been around for decades and has become an indispensable tool for photographers and other content creators. It offers an extremely rich feature set which can be an obstacle to learning the critical parts. Now, you have an opportunity to take a 13-hours of Photoshop course totally free of charge. There is no payment, credit card information, just login with your Adobe, facebook, or Google+ account and start learning the tool. You can learn at your pace and stop at any point, rewind, review, practice, and move forward.
To learn more about this free offer, visit ProDesign Tools Website and sign up for the free Photoshop course. While there, take a look at the other offers they make available. I have not looked at those and am not sure if the other offers may want your credit card number or not.
