#here is ur answer

#Black and white photography brings out details and contrast.

#The way black and white photographs are created depends on the exposure of light sensitive material which forms the image, in terms of film photography. It starts with silver halides which is the light sensitive material, known as AgBr. AgBr is exposed to form the image depending on the frequency of light which is involved in this process. After being exposed to light, the AgBr forms an image on the film. When developing the image, the exposed AgBr grains convert to visible metallic deposit using an oxidized reducing agent, sodium sulphate.
