The Effects of Ultraviolet Light on Variable-Density Recording and Printing
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.
