Not many people would know who russell brown is or for that matter have their photo taken with him (score two for me). He is crazy and wacky and i would actually not reccommend taking a course from him or sitting through one of his lectures. I would however reccommend watching some of his quicktime movies on the techniques of photoshop.
His web site can also be found at
Go to the first site posted here and scroll down to the photoshop cs section. I would start with the camera raw movie. If you dont already shoot exclusively in raw mode you may reconsider.
