The Cyanotype process is a 19th Century photographic process that uses iron salts and sunshine to create a beautiful Prussian Blue colour; it is the original 'blueprint'. In the 1800s, botanist Anna Atkins was the first person to use photographs to illustrate a book by using Cyanotypes and this is the same process that I use today.
