This course was exactly what I needed. Although I had been messing around with PS - messing is the key word here - and have several excellent but huge books on it, I found myself always limited to one or two tools. When I am working on a photograph I really don't want to start learning how to use some tool, or even figure out which one should I use. I found that books are great as references once you learn how to use PS, but not so hot for basic learning.
Then I watched this course and it solved my problem instantly. Sef is a great instructor and everything he says and shows you has a purpose, is to the point, and is very instructive. What he shows you is the tool in action on a photograph. For me everything he demonstrated was a 'so that's how it works and what it does' moment. So if you are new to Photoshop, watch this course - you cannot lose and it is sure to help you out.
