The Cyanotype printing process was invented in 1842 by Sir John Herschel, an English, astronomer, chemist, and experimental photographer. He searched for ways to introduce colour to photography, which was in its infancy. The cyanotype process uses light-sensitive iron salts produced by brushing solutions of ferric ammonium citrate and potassium ferricyanide, also known as Prussian blue, onto paper. The cyanotype is also the originator of the architect's blueprint. I have used Herchel‘s original formula for my prints.
I felt that the Cyanotype process was right for my work, not only because of the colour of the prints which evokes the deep blue of the ocean and the nostalgic feeling it evokes but also because the images are developed by using sunlight (UV light) and water which is most relevant for this subject matter.
