I am taking a photography class. The next assignment will be portraits. I'm guessing most people in the class will just be doing portraits of friends around campus. I want to do something that will invoke a little more emotion and make more of an impact on someone and am brainstorming ideas. Does anyone have any suggestions? I was thinking about doing something highlighting homelessness (portraits and some blurbs from homeless people in San Francisco or Santa Cruz) but I am worried that this is done often. Any help?
