Abstract
The effect of using ultraviolet filters on the gamma of negative and positive development is discussed. The effect of ultraviolet light on image quality is discussed and a mathematical analysis is given explaining the existence of spurious side images found in white-light recording on clear-base variable-density negatives. Low-end frequency rise, attributed to existence of these side images, is eliminated by recording with ultraviolet. Reduction in wave-shape distortion as well as improvement in high-frequency response is attributed more to use of ultraviolet in printing than in recording. Practically no gain in signal-to-noise ratio is found by using ultraviolet in either recording or printing.
