The mobile photo sharing app Instagram has been in the news a fair amount recently, as it announced that it is developing an Android version, and also netted a high-profile user in President Barack Obama. Certainly, some people are skeptical about the merits of cell phone photography, but it's obviously a phenomenon that is here to stay. A couple of days ago, I was talking with my friend Seth High about the way he uses his cell phone for his photography. Seth has been taking pictures for over 20 years, using film and digital in equal measure. He was raving to me about how he was going through each of the different filters in his camera app, and how each setting would force him to shoot photos as if he was learning to photograph for the first time, taking into account the ways that each filter would treat different types of light. Much like using a toy camera, the limitations of each filter forced him to think about composition in a very simple way. It was exciting to hear him talk about how this app had brought him back to his early days of photography.
