you can't really beat old school street photography, especially in medium format
here's a blog I discovered just now that will really make you want to take hold
of your grandmother's old "Rolley"and just go snapping pictures in the next street corner.
(there's no such thing as snapping with these old heavy cams)
every composition is carefully planned
exposesures are mesured precisely
thanks to John Maloof who manages the blog. His website also deals with street photography.
