New Emulsions and Sensitometry

  • A. Maury
Conference paper


Whenever and wherever plates are sensitometrically tested, the purpose is usually to find a correct hypersensitisation time for a new batch of emulsion. Using a sensitometer and a densitometer, primary information is measured: Fog level, speed at fixed density and gamma. From them, the astronomer will derive other information such as hypersensitisation time (or baking temperature...) and exposure time, using a rule of thumb, such as “the optimum fog density level is 0.3 diffuse”.
