I bought this gift for my father for Christmas, he was looking for a book on the D90, but none are currently available, so i thought a DVD would be better. AND BOY WAS I RIGHT! This DVD is very professionally done, and it can literally show and walk you through all the features as opposed to a book which is more limited in showing multiple images and steps in a print format. With the video, they literally just show you each step and it's very detailed and thorough. He enjoyed it, and plans to watch it a couple of times. THey also share some tips at the end which are really helpful to hear a professional share. Enjoy if you don't like to keep a book or flip through those!
