No-one? I was wondering whether it was worth going, but from the non-response I guess either not many people attend or they don't come with high recommendation?!
I've attended several of the Kelby one day training seminars. Some have been very beneficial and others left me dissatisfied. When dissatisfied, usually a result of the material being to basic for me, or too large a crowd for the room..
I get more out of the Kelby training website, books, talking with other photoshop enthusiasts, or just experimenting with photoshop on my own.
One thing you need to know, IMO don't take a lap top, there is no time for hands on usage while the seminar is going on. Plan on just following along, taking some notes and when you get home start trying some of the techniques, lessons learned.
