A Pinch of Salt should have great possibility to expose the artistic expression in Mega-pixels Age. Salt paper printing is one of very early 19th century Photography process. which is result of Sodium Chloride and Silver nitrate on paper.After that fix with (HYPO) Ammonium thiosulfate or sodium thiosulfate.
Here we are focusing on alternative Image making culture . (alternative word given by Digital Age)
Historical Reference for the salt process
The technique of making salted paper prints dates back to the earliest days of photography. In 1802 Thomas Wedgewood and Humphrey Davy used silver chloride to make printed out images on paper. They did not, however, discover a way to secure these prints permanently. Several years later, Nicefore Niepce also made prints on paper using the same process, before his investigations into the light sensitivity of asphaltum.
William Henry Fox Talbot experimented with the proportions of silver nitrate and chloride to establish the most effective combinations for printing out images, by contact and in the camera obscura. At this time Talbot discovered that an excess of chloride made the paper less sensitive to light and used this effect to stabilize his prints. In addition to chlorides, Talbot also used potassium bromide and potassium iodide for print stabilization.
When Sir John Hershel suggested the use of sodium hyposulfite (sodium thiosulfate) as a more efficient fixing agent, the salted paper print had “arrived.”
