"Of what use is a dream if not a blueprint for courageous action."
These cyanotypes have been created using the traditional cyanotype photographic process invented by Sir John Herschel in 1842. The cyanotype process is distinctive for producing rich, cyan-blue prints. High quality watercolour paper is initially coated with a mix of two chemicals - ferric ammonium citrate and potassium ferricyanide - and allowed to dry. The treated paper is then re-wet using various liquids prior to the placing of plant material on top of the paper. These liquids create a further chemical reaction with the original cyanotype chemicals. The print is then placed in the direct sun to develop. After developing, it is washed and dried. Whilst a time-consuming process, the finished print is always unique, unable to be replicated and sometimes very beautiful!
