The birth of photography in the early 19th century was soon followed by a second wave of experimentation aimed at mechanically reproducing photographically caputed images rapidly and more permanently for the purpose of publishing. One of the key factors in unlocking this groundbreaking possibility was demonstrated throught the French inventor Alphonse Louis Poitevin's 1855 experiments concerning the light hardcening action of chromates on colloids.
