You can learn a lot from taking photo classes in college. But, there's also a lot of knowledge out there that you won't get from many professors. That's why honest books like Zack Arias's Photography Q&A can come in very handy. The subject matter is taken from Zack's blog, which answered real questions from readers with matter-of-fact honesty that's very refreshing.
It's a nice supplement to the straight up technique and history stuff that many intro photo classes tend to teach. It's also an entertaining and colorful read, which can be a nice break from the land of academia.
