I just happened to stumble on this project http://thomashawk.com/2008/06/introducing-christopher-and-start-of-my.html and for a lot of you I follow, I thought this was a really neat idea! For me, unfortunately, the amount I actually get into the city is rare, so I won't be able to do this for some time, but I may have to add "A $2 Portrait" to my photog bucket list!
What a great idea, assuming they don't try and steal your camera (sorry I can be a cynical so and so sometimes, LOL)! I look forward to seeing some 365 $2 photo's!
I'm with Dave, two things I lack. But I suppose if I started carrying around cash I would love the opportunity to interact more positively with my fellow human beings.
