TONING CYANOTYPES
Do you desire timeless classic sepia photographs? Angela Chalmers reveals how to create a nostalgic look by toning cyanotype prints
Alternative photography has become increasingly popular over recent years, both in art galleries and on social media platforms. The traditional cyanotype print is known for its beautiful Prussian blue tones and is admired for its eye-catching qualities. However, cyanotypes don’t always have to be blue and can be manipulated by a simple yet engaging step that transforms them into sepia-toned images reminiscent of early photography.
This is done by using natural tannins as the toner, which not only adds variety to the prints but also allows you to explore the possibilities of what can be done with this art form. Tannin is a remarkable organic chemical compound found in trees and plants, green and black tea, coffee, and red wine. The tannins chemically bind to the iron salts impregnated within the cyanotype during toning.
Toning cyanotypes Toning cyanotypes typically requires two basic steps: bleaching and toning. Bleaching is primarily done to lighten, fade and reduce the blue so that the toner can produce an alternative colour. The pH value of your tap water can also play a part in the process. If it is high (over pH 7), you may not need to bleach at all. Soaking your cyanotype in fresh, clean water for a few hours should reduce the blue because of its high alkaline content.
To prepare a bleaching solution, use sodium carbonate (soda
