I think of it as just unplanned, unobtrusive photography in an urban setting, capturing events unfolding naturally.

Great street photography requires ironic vintage gear and wardrobe. Both can sourced from a thrift store or from an Ebay seller in the former Soviet Union. Having a mechanical typewriter helps (for blogging), as does a Victorian-era bicycle. Grow a mustache. If you want to be truly misunderstood as an artist, create high contrast b&w images that are underexposed and out of focus.

$100? You pay peanuts, you get monkeys.
