The Cyanotype print/photogram process was originally invented in Birmingham by John Frederick William Herschel (1792-1871) as a cameraless photographic technique. This was subsequently used to produce the first illustrated book of botanical prints produced by Anna Atkins (1799 – 1871). The book was called British Algae: Cyanotype Impressions. 

My father remembers going to the blueprint shop early on in his working life as an engineer in the car factory, and asking for a blue print. This was then produced using the original Cyanotype formula. He remembers that the print room always smelt of ammonia. 

After mixing the solutions myself, I painted the surface of simple print paper. The paper was poor, disintegrated in the washing process and the blue tone was very light.  I continued to experiment with the process, producing both dry and wet cyanotypes. 

I documented this experimentation in my sketchbook, working through a variety of mediums, natural forms and found objects as well as using my body to cast shadows, noting the intensity, direction and time of the exposures.
