Customer review : Stunning product! This is obviously not prepared by the same people (the IRS?)who brought you the 90 pages of hell Nikon instruction manual for the "basic" SB-600. All techniques were clearly explained, demonstrated, and summarized following each shot , including the before and after sequence to reinforce the enhancements made for each technique. I particularly enjoyed the application and variations to the techniques discussed and demonstrated by Bob Krist and Joe McNally
