Photography
When working with wet photographic plates, Swan noticed that heat increased the sensitivity of the silver bromide emulsion. By 1871 he had devised a method of using dry plates and substituting nitro-cellulose plastic for glass plates, thus initiating the age of convenience in photography. Eight years later he patented bromide paper, developments of which are still used for black-and-white photographic prints.

Famous quotes containing the word photography:
“If photography is allowed to stand in for art in some of its functions it will soon supplant or corrupt it completely thanks to the natural support it will find in the stupidity of the multitude. It must return to its real task, which is to be the servant of the sciences and the arts, but the very humble servant, like printing and shorthand which have neither created nor supplanted literature.”
—Charles Baudelaire (1821–1867)
“Too many photographers try too hard. They try to lift photography into the realm of Art, because they have an inferiority complex about their Craft. You and I would see more interesting photography if they would stop worrying, and instead, apply horse-sense to the problem of recording the look and feel of their own era.”
—Jessie Tarbox Beals (1870–1942)
