For my photography final we are doing a portfolio and I came up with this awesome idea of shooting what people care about most in their life. It goes well with the upcoming holiday(s). I would think that would be an obvious theme but my teacher says no. I guess I'm not understanding this concept of "theme." Apparently every picture has to be related to each other in a physical sense. He gave me an example of shooting someone's favorite car or vehicle. So every picture would basically be the same. I'm not particularly fond of that. This is a 10 photo portfolio... I don't want to shoot that many things that are basically the same. Is he right? If so, can someone maybe explain to me how "theme" works? The photos I was thinking of putting in this portfolio for what we value most are along the lines of family, their dog, and love, and .. other things people find important in their life. I thought it was a cool idea. He did say that "family" would work better as a theme.
