Also, the washout is the most extreme form of overexposure, which is the act of exposing each frame of film to more light or for a longer period of time than would be required to produce a "normal" exposure of the same subject. There is little or no visible detail in the highlights - the bright areas of the picture - and images appear bleached, more or less washed out. The effect is accomplished by directing the camera at a bright light source that would wash out most, if not all, of the frame area, or by having the effect processed in the film laboratory. While in 2014 some motion-picture directors were still opting for film emulsion-based photographic materials rather than digitally retrieved imagery, the number doing so was rapidly decreasing.
