>but if you have a feel for it just buy some books.

I agree with that. There are so many forums as well dedicated to specific niches, 2d/ 3d design, you can just ask for help from there.

I teach classes, but they are just 1 day classes that comprise 7 hours of a subject. There are 5 levels of photoshop that each are 7 hours long. For other subjects there might only be 2 or 3 classes. It is in my opinion a better way than a long class. Books are also great but unfortunately there are many books that dont do a good enough job of explaning why certain things do what they do which helps in using the software fully.
