Salt print process with the help of Potassium Bichromate

with 7 comments

Salt print process was invented by Henry Fox Talbot in 1839 and it’s known as a very low contrast printing technique. From The Book of Alternative Photographic Processes I’ve learned a technique to chemically raise a contrast of a salt print. You add a drop or two of potassium bichromate to a 28ml of sensitizer and heat it up to about 40C, expose it in the shadow, best under daylight UV skylight and then do a 5 minute prewash in a hot (cca 40C) distilled water with another 3 drops of potassium bichromate. It does raise a contrast, but it also cause speckling so you need to work with heated solutions and expect that it will not work the first time. Check how many test prints I’ve done until I figure it all out…
