Cyanotypes also known as Sun or Solar Prints.
Formulary's New Cyanotype Kit was formulated by Dr. Michael Ware. This formula was published in the Jan / Feb 1997 issue of Photo Techniques. According to Dr. Ware, the New Cyanotype processes uses a single sensitizer solution. It boasts a long shelf life and makes prints with an excellent stable blue color and a long tonal response. The speed is much faster than the traditional process. It also loses little, if any, blue color in the final wash water, and is much more suited to a greater variety of papers. This kit will produce approximately 50 8x10 prints if the sensitizer is applied with a glass coating rod.
