Photo exposure meter Leningrad
Leningrad is the name of a family of Soviet exposure meters.
Light meters “Leningrad” make up a series of models of seven types. The first models were produced with selenium photocells having a top electrode with a translucent gold coating. Exposure meters of the latest releases have a top electrode of a selenium photocell made of cadmium oxide. They are more sensitive to light and more stable in time and fatigue. All selenium exposure meters are designed for relatively high brightness. One of the models (Leningrad-6) uses a cadmium sulfide (CdS) photoresistor.
