Experiments with Cyanotypes

Table of Contents


Cyanotype is an image-making process that uses two chemicals, ammonium ferric citrate and potassium ferricyanide. When these two compounds are mixed together and applied to a surface (such as paper) the surface becomes photosensitive and can be used for contact printing. One of the great things about the cyanotype process is that images can be created in sunlight and developed with plain water. Cyanotypes were also the original technique for producing blueprints.

This page is intended to be a living document cataloging various approaches I have personally tried in respect to the cyanotype process.
