Sir John Herschel discovered through experimentation with “deeply colored salts” reacting with metallic compounds of a ferrous nature when exposed UV light how to create a stable, monochromatic photographic image whens the chemicals are combined and applied to an aborbent surface . Ferric ammonium citrate becomes ferrous when exposed to UV light; using this, potassium ferracyanide (as suggested to him by a friend) a permanent mark is then made and water is then used to fix the images*
| a term and process that Herchel invented |
I found Lisa McCartney’s Sunprints about 5 years ago at a local used book store when I no longer had access to a darkroom; its a collection of salt and cyanotypes. Her grainy, delicate, beautifully frozen moments were so inspiring.
This having inspired me to publish a book of my own prints, I was even more motivated when I learned that a woman named Anna Atkins in 1853 printed and published a book of hundreds of handmade images using the cyanotype process; this was the first use of photographic printing for accompanying scientific visual.*
I am quite found this process for its very little use chemicals and processing, its lovely color and the ability to manipulate the image in an infinite number of ways.
