I use photoshop for many years, and I know how to use many of it's functions, even though I could not call myself a professional. I 've also read some related books about photoshop, but this happened many years ago(>ten) on old versions. I am not an artist, am not a photographer also. But I really like photoshop, I use it in combination with many of my web projects, and I think I achieve good results. I am also interested in photo manipulation. If I invest, time and money, in one book, that explores all the new and all the classic tools of photoshop, which book this should be, among the hundreds that hit the market? I will dedicate my time and money, and I want to read something that is really essential, and really matters. Something that will expand my knowledge about it and will be a companion in my explorations for the years to come. I wait for your suggestion.
