Thanks for posting this, Clayton. To be sure, there's good info in there. But you must have the patience and tolerance of sitting through the typical over-caffeinated aging 30-something hipster-with-new-baby style that's become the dial tone of everything Kelby. (The presenter here spends the first 5+ minutes just plain yapping about himself and what he's going to do...no kidding.)
For those who prefer a quieter, more direct, and ever richer gold mine of tricks along these lines may I recommend Scott Kelby's
Photoshop Channels Book. It's genuinely unique and features some terrific techniques. While I would have to be sedated to tolerate Kelby's Photoshop Empire in-person I very much like his style of print instruction; it's a problem-oriented outside-in approach versus the encyclopedic style of other authors.
