What college courses do you have to take in order to be a photographer?

You will undoubtedly have to take some basic courses (history, algebra, English, etc.). Then you will take 30-60 hours of classes in photography, art, or whatever. It really depends on the university. You need to take basic art courses that teach about color, contrast, composition, texture, etc. You also have to take basic chemistry and learn how light travels and is diffused or reflected. There's really not a whole lot to getting started. Studying the work of famous photographers helps, as does working as an understudy to a professional.
