Creek Oaks


Oaks at Crane Creek Regional Park in Sonoma County, California.
This is a new direct positive process developed by Ricardo Leite and Joe Van Cleave. You are looking at the same photopaper that was in my coffee can pinhole camera, not an inverted scan or contact print. It uses hydrogen peroxide and citric acid instead of more toxic and dangerous chemicals like potassium dichromate and sulfuric acid. This particular one was made even more safely by using weak 3% hydrogen peroxide like you can buy at any drugstore.
