You need to visit this site to see the incredible street photography of Vivian Maier.
Maier died a few years back before her work was discovered or appreciated. She left behind nearly 100,000, mostly medium format negatives and thousands of prints and undeveloped rolls of film. It’s being archived by a guy call John Maloof in Chicago who came across them in an auction. Not much is known about her life but her photography is just amazing.
You can view a brief CBS documentary here.
