Fotospeed Cyanotype Sensitizer - 50ml (Makes 30 - 8x10 Prints)

Cyanotye is an alternative process exposed by Ultra Violet/Sunlight through use of contact negatives to produce a blue image on art paper of your choice.

The Fotospeed Cyanotype Sensitizer is a single working solution and is an updated version of the original process. This formula uses Ammonium Ferric Oxalate to give a good blue, which does not wash out and is twice as sensitive to UV as the traditional version. Development is in water. A citric acid solution 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 or the placement of an object on the sensitized material.
