Query: A good book for intermediate photoshop users

4 stars for intermediate users, 3 stars for advanced users.Intermediate users will benefit from these tutorials a lot if they take enough time to ponder what they just did, as not everything is explained.Advanced users will learn less, but it is a good excercise book for them, they can compare their techniques to those of Mr. Aymes & learn about shootings in real life.As for beginners, they stand to learn the most, but I can't judge whether there is enough information/context for them to understand what they do.
