I am kind of new to Street Photography. Not that I've never done it, just not a lot of it. But it can be quite interesting. Street Photography forces one to look at the world with a different eye. This is not photo journalism, editorial, or commercial. It's not formal portraiture (assuming people in the image).
Most of my Street Photography will be in Black and White. I think B&W lends itself more to this style of the photography. Color images will only be included if the color makes a statement of some kind itself. The color must be there for a reason.
