Cynotype is the first ever photo chemical process that was invented in 1843. Cyno means blue. Hence, the chemical used for the process only produces blue and white prints and can be developed on watercolour paper, fabric, glass and wood. It can also be done on chemically infused paper and can be toned with coffee, tea, green tea and wine that result in lending the pictures beautiful dark blue, brown, yellow and purple tints. This is a slightly easier version of the regular dark room method of photo processing. Please contact 93461-03050 for further details.
