I love Colin's dry sense of humour and it makes his courses more interesting than simply giving a lecture. Colin has years of experience and knows the information he's teaching. He's right that channels are intimidating and you have to make up your mind that you're completely open to learning about the more challenging aspects of Photoshop. And, if you think this subject could be of value to you and your work in photo editing, then buy it. A once over, even three times over, isn't enough. My approach is the go with the live (or re-run) and decide if I should incorporate it into my work, watch the free presentation as much as I can, decide if I want to learn and practice and buy it. No one can learn everything they need to know in a one-day video class. Hands-on practice, being able to pause it, practice, go back, try again and do that for many days so you can make it automatic. Don't get frustrated, take in little bits, even if it's only 10 minutes with a little practice. That's my approach. These "short courses" that are only an hour or an hour and a half, have an incredible amount of information in them. They aren't easy but they're gold.
