A Different Stripe, the NYRB blog, writes about photographer Richard Howe’s Street Corner photography project.
Howe assigned himself the project of photographing every single one of almost 11,000 intersections in New York City. His web site gives you a few different ways of viewing his photos.
Howe’s work is in that category of photography that follows the psychology of collecting, where the photographer builds a complete set of something (like street corners, for example).
I think digital photography makes this even easier to do than print photography did — sites like Flickr, I think, really facilitate this approach, giving photographers the option to create sets and other kinds of groupings.
I know that, in my own work, I create sets just so that I can collect images falling under those set categories.
