This video was shot by a German film crew in the early 1980s, and shows American street photographer Garry Winogrand at work. Although he died of bladder cancer at age 56, his photographic output during his lifetime was enormous, even compared to other photographers:
Consider this: at his death, Winogrand left behind 2500 undeveloped rolls of 36-exposure 35mm film (mostly Tri-X), 6,500 rolls of film that had been developed but not contact-printed–not to mention 300 apparently untouched, unedited 35mm contact sheets.
Do the math. Conservatively, that’s at least 300,000 pictures – equal to at least two life’s work for anyone else–that Winogrand took but never even saw, so busy he already had been photographing the world around him. [#]
That explains why Winogrand is able to load new film into his Leica so effortlessly while talking to the camera — he could probably do it in his sleep.
