Paper on Lippmann Photography
The True Colour of Photography
by Hans Bjelkhagen and Darran Green
It is possible to record modern Lippmann photographs without using a mercury reflector. Instead the Fresnel reflection between the emulsion and air is sufficient, with the plate located in a special dark slide. This makes it much more practical (and safer) to record modern Lippmann photographs including large plates.
Chapter 2 in the Ultra-Relistic Imaging book is devoted to Lippmann photography with detailed information about old and modern Lippmann photography.
