Exposing "Cyanotypia Cita" with a simple Flash Light

In this short video I show the sensitivity of the new "Cyanotypia Cita" process. This formula even works with a common LED flash light.

To expose iron prints by using a normal light source opens completely new approaches for teachers and classes, because UV light sources are not always everywhere available. The other huge advantage is the simplicity of the chemistry. "Cyanotypia Cita" is harmless, easy to use and has a good stability for storage.
