after hearing about "Mastering the D90" I went out and picked up a copy yesterday and I have to say I'm very impressed with the way the book is laid out as well as the writing style. Previously I had borrowed a friends D40 along with a copy of "D40 for Dummies" that I found to be useful to someone that is brand new to the world of photography as i am. I quickly realized that after reading the users manual for the D90 that I would want another book. This is a far more comprehensive book with much more detail and technical info yet still easy enough for a nube like myself. excellent job!! thanks so much for a great resource!
