TY - JOUR AU1 - Bjelkhagen, Hans I. AB - At the end of the last century, Gabriel Lippmann was experimenting with color photography. His photographic color recording technique, Lippmann photography, produced very beautiful photographs and the fact that the colors are preserved in the early Lippmann photographs indicates something about their archival properties. Recent progress in color reflection holography has made it possible to take a new look at this one hundred year old photographic technique. Today, high-resolution panchromatic recording materials suitable for Lippmann photography are on the market. In particular, the Slavich panchromatic ultra-high- resolution silver-halide holographic materials have been investigated for modern Lippmann photography. Since the color photographs contain no dyes or pigments their archival stability may be high. In addition, a Lippmann photograph is difficult to copy which makes it a unique color photographic recording. Both of these features must attract a photographer interested in creating beautiful art photographs. It is also shown that Lippmann photographs can be made without the mercury reflector, instead by using the reflection from the gelatin-air interface. This eliminates the complications in dealing with mercury, while still maintaining the high resolution and picture quality at the expense of longer exposure times. Security application is a potential field for Lippmann photographs as well as optical filters. Another advantage is that no expensive equipment, such as lasers, is needed to explore this photographic recording technique; only a modified camera is required.
