I have been using numerous versions of PhotoShop for many years, since CS2, and several versions of PhotoShop Elements…I can honestly say, as a former teacher myself, that your approach to instructing PhotoShop is by far the most effective of any I have seen. Your ability to break each difficult technique into simple steps, with clear though intricate, easy to follow exercises, followed by assignments that give students enough guidance that they can experience success at each stage of discovery --while encouraging guided experimentation with each process -- is an example of true teaching mastery. It is obvious, as you note, that you have been teaching PhotoShop for a long time, with a passion for helping others share in your passion.
