Brilliance in Blue - What are Cyanotypes?

Cyanotypes are one of the oldest photographic printing processes in the history of photography. The distinctive feature of the print is its shade of cyan blue, which results from its exposure to ultraviolet light. When the blue print emerged, cyanotypes were traditionally used for reproducing the technical drawings of architects and engineers until the arrival of photocopy machines. However, with its versatility and affordability, the technique was adopted by photographers soon after its discovery. The early days of photography were characterised by monochromatic prints such as the Daguerreotype and Calotype, and thus the brilliant blue hue of the cyanotype made a striking entrance when it was introduced in a world of albumen and silver gelatin prints.
