I am a high school teacher who will be teaching a Photography/Graphic Design course in summer school this summer. I would LOVE to get a whole heap of advice from you all. I am looking for general direction for this whole thing. 2.5 hour classes every day for four weeks. We have new imacs, NikonD80s, and CS3 for all students. What do you think i should do with this? Some students will have little to know photo background.
