celluloid roll film (1 ene 1835 año – 1 ene 1887 año)

Descripción:

Metal and glass plates were fragile, cumbersome and hard to work with, and costly for the average person. A more accessible method was looked for by photographers.
A combination of two technologies, silver halides and celluloid based emulsions continued getting better. In 1835, Henry Fox Talbot invented a viable method of spreading a gelatine emulsion on paper.
