One thing I learned after working on the "Streets of Manhattan" series thing I've been putting up lately is that street photography is just like noir film...on matter what you do, it inevitably and unceasingly and ANNOYINGLY begs to be in black and white.
The only reason why I left the majority of the photos in color was so I could see whether or not I could pull off leaving it in color...I think several of them would have looked better in BW, but whatever. I was seeing BW street shots everywhere...no color whatsoever.
I guess there's a reason why it's all mostly BW too...since generally they look perfect that way. haha.
