Assertion is correct but the reason is False
Explanation: The mail reason silver salt, Silver Bromide is used in photography is because it decomposes into bromine and metallic silver on light exposure. This is the main property that made it perfect for black and white photography
When AgBr is suspended in a gelatin solution,  the AgBr grains create a special emulsion. When this emulsion is exposed to light, AgBr decomposes into silver and bromine and a photographic image is preserved.
