Lippmann plate sample set

Lippmann plate still lifeThis sample set consists of one Lippmann glass plate, 4 3/4" x 3 1/2". It is a modern example of an early color photographic process invented by Luxembourgian physicist, Gabriel Lippmann (1845-1921), which earned him the Nobel Prize in Physics for 1908. This method for reproducing colours by photography is based on the interference phenomenon. The photograph is composed of a silver image in an albumen binder. The spacing of the particles is the key to the interference between light waves that creates the color. This plate requires a higher humidity (more swollen image binder) in order to have the correct image particle spacing and create true colors. Breathe gently on the plate as you would when cleaning a pair of glasses and watch the colors change. Each plate is unique, but is similar to the one shown here.
