The Screen Tests are a series of short, silent, black-and-white film portraits by Andy Warhol, made between 1964 and 1966, generally showing their subjects from the neck up against plain backdrops.
The Screen Tests, of which 472 survive, depict a wide range of figures, many of them part of the mid-1960s downtown New York cultural scene.
Under Warhol's direction, subjects of the Screen Tests attempted to sit motionless for around three minutes while being filmed, with the resulting movies projected in slow motion.
Warhol varied the shooting conditions for individual films, changing the number of lights or their angles to alter the pattern of shadow on the subjects' faces and the backdrops behind them or using different lens aperture settings.
