Since I tend to carry around weird-looking cameras, I get a lot of comments...most people are barely aware that there are other types of film besides 35mm, let alone cameras that use different films. I've explained 120 to my own mom like 6 times. I get funny looks from 'real' camera users, too. The guys with the 3-foot barrel that shoot of 6 shots with a single click. The Fujipet gets outright stares, from the camera to my face, up and down. And nothing like squatting on a busy sidewalk to develop a polaroid to garner some curious looks.
As for the low-fi hassy shots, I get the 'experimentation' part, but just buy a holga! I think lot of these photographers would be embarrassed to carry one around. no street cred, I guess.
