Feeling Blue - a photo on Flickriver

Feeling Blue

The Cyanotype is an early photographic technique (1842) developed by the Englishman scientist Sir John Herschel. [I once had a pet rooster I called 'Herschel" after his famous astronomer father, William Herschel.]

The technique which John Herschel called a Cyanotype, is a photographic printing process that produces a cyan-blue print. Well into the 20th century it was still being used as a simple and low-cost process to produce copies of drawings, referred to as blueprints. The process uses two chemicals: ferric ammonium citrate and potassium ferricyanide.

In recent years there has been a revival of artistic interest in the cyanotype. We've already seen how Anna Atkins used it for her scientific work, but a number of artists are now turning to it as a means of capturing sunlight and making beautiful images. For those interested I'll provide the following links:

The most comprehensive book I have on the subject is Christina Anderson's, "Cyanotype: The Blueprint in Contemporary Practice" (Routledge, 2019). It has some wonderful examples of contemporary work.

This photo above is my tribute to the process. Obviously it is not a true cyanotype and I have merely tried to match the image using digital colour toning. I'm hoping that in the near future I will be able to actually produce some real cyanotype images, scan and upload them on this page.
