CYANOTYPE / BLUE PRINT
The Cyanotype process, originally created by Sir John Herschel in 1842, is also known as a “blueprint” process. The final print is characteristically blue in color. The cyanotype print is also known as a “non-silver” process, since it employs ferric (iron) salts for its photosensitivity, from a combination of two solutions, one containing ferric ammonium citrate and the other solution containing potassium ferricyanide. Combining these complete solutions in equal parts creates a sensitizing solution which is then brushed or painted onto the surface of a substrate like cloth or hot-press watercolor paper.
I made my first cyanotype in 2015. I was attracted by the blue images and wanted to test the cyanotype process to see what it had to offer. I ordered some chemicals and spent an evening coating paper. The results of the printings surprised me. The dark room has always fascinated me. But the sun print was much more impressive and the results were spectacular. Especially wet cyanotype that I use make me so happy because its all ‘happy accidents’.
