Silver salts

Silver salts are light sensitive chemical compounds. When exposed to light – either in a camera (in the case of film and negatives) or in the dark room (photographic papers) – the silver salts react by darkening in proportion to the amount of light reflected from the subject.

Silver bromide Print

Silver bromides share the features of all silver gelatin prints, giving deep rich blacks and crisp whites on a high gloss paper, as well as having good archival properties. Compared with silver chlorides or chloro-bromides, they have a neutral, deep black tone.

Silver chloride print

Silver chlorides share the features of all silver gelatin prints, giving deep rich blacks and crisp whites on a high gloss paper, as well as having good archival properties. Compared with silver bromides or chloro-bromides, they have a cooler, bluish-black tone.

Silver gelatin print

Silver gelatin prints typically give deep rich blacks and crisp whites on a high gloss paper. They have extremely good archival properties, lasting over 100 years without visible fading if kept carefully. There are three key types of black and white gelatin prints: silver bromide, silver chloride and chloro-bromide.
