While most folks who collect photography are interested in archiving the work of gifted photographers or in preserving particular subject matter, there is a small breed of collectors who prefer to search out the work of anonymous amateur shutterbugs who recorded the seemingly mundane events of their existence. Other People's Pictures is a documentary which focuses on a handful of collectors who frequent New York City's Chelsea Flea Market where they search through the lost and discarded images of people they've never known. The collectors look for moments in the lives of strangers that spark their interest, ranging from an Asian-American with a fondness for Hawaiian Tiki kitsch to a man who collects photos of men in vaguely homoerotic poses as lost artifacts of pre-Stonewall gay history.
