Watch CineCalidad. The films were made between 1964 and 1966 at Warhol's Factory studio in New York City. Subjects were captured in stark relief by a strong key light, and filmed by Warhol with his stationary 16mm Bolex camera on silent, black and white, 100-foot rolls of film at 24 frames per second. The resulting two-and-a-half-minute film reels were then screened in 'slow motion' at 16 frames per second.
