Acidic
Salted

Salted paper, the foundation of the calotype process pioneered by Henry Fox Talbot, revolutionized photography. Unlike the daguerreotype's intricate and toxic mercury-vapor procedure, Talbot's method employed chemically sensitized paper coated with silver salts, making it far more accessible and versatile. This invention marked a momentous leap forward, setting the stage for modern negative-positive photography and contributing to its widespread adoption.
