The salt print was the dominant paper-based photographic process for producing positive prints (from negatives) from 1839 until approximately 1860.The salted paper technique was created in the mid-1830s by English scientist and inventor Henry Fox Talbot. He made what he called “sensitive paper” for “photogenic drawing” by wetting a sheet of writing paper with a weak solution of ordinary table salt, blotting and drying it, then brushing one side with a strong solution of silver nitrate. This makes the paper light sensitive and is exposed when dry.
