One of the earliest photographic printing papers, attributed to Fox Talbot, was made by coating paper with Sodium Chloride (Salt) and Silver Nitrate. Objects were placed on it and then exposed to sunlight for a number of hours. The resultant print had a distinct texture and could vary in colour from brown through yellow to violet.
