Citric Acid 100gms for use with the Fotospeed Cyanotype process. Cyanotype is in a single solution, and is an updated version of the original process. Using Ammonium Ferric Oxalate to give a good blue that does not wash out, this solution is twice as sensitive to UV as the traditional version. Development in water and citric acid can be used to manipulate contrast. All images are made by the contact system, where the image depends on a negative of the appropriate size.
Contains: Sensitiser 50ml (sufficient for 40 - 8x10in applications)
