What is bromide paper? It is simply papercoated with gelatino-bromide of silver emulsion,similar to that which, when coated onglass or other transparent support, forms the familiardry-plate or film used in negative-making. The emulsionused in making bromide paper, however, is lessrapid (less sensitive) than that used in the manufactureof plates or films of ordinary rapidity; hence bromidepaper may be manipulated with more abundant lightthan would be safe with plates. It is used for makingprints by contact with a negative in the ordinaryprinting frame, and as the simplest means for obtainingenlarged prints from small negatives. Sometimesbromide paper is spoken of as a development paper,because the picture-image does not print out duringexposure, but requires to be developed, as in negative-making.The preparation of the paper is beyondthe skill and equipment of the average photographer,but it may be readily obtained from dealers in photographicsupplies.
What are the practical advantages of bromide paper?In the first place, it renders the photographer independentof daylight and weather as far as making printsis concerned. It has excellent “keeping” qualities,i.e., it does not spoil or deteriorate as readily as otherprinting papers, even when stored without specialcare or precaution. Its manipulation is extremelysimple, and closely resembles the development of anegative. It does not require a special sort ofnegative, but is adapted to give good prints from negativeswidely different
