The cyanotype kit is two part solution relatively inexpensive and easy to use. After exposure to UV light (sun)the image is developed out in water – no other chemicals are required. Colour may be easily modified by a variety of toning agents – it can be applied to fabrics and other surfaces.
The characteristic cyan blue colour is embedded in the fibres of the paper.
