Cyanotype is a simple and fascinating historical photographic technique<\/strong> that produces prints with a characteristic shade of blue, known as Prussian Blue<\/strong>, which is achieved by mixing two iron salts that are sensitive to the ultraviolet part of sunlight. This is a contact printing<\/strong> technique; the negative or the object you want to get on the image is placed in direct contact with the sensitive paper and then exposed to sunlight. It is a simple process that can be done at home.Let’s see together how it works and how you can make your first experiments.<\/p>\n\n

\n\n

Where does it originate? <\/strong><\/h2>\n\n

Invented in 1842 by Sir John Herschel, it was initially used to reproduce documents<\/strong> and diagrams, but has become an art form valued for its aesthetic qualities and simplicity. Consider that the first photographic use was pioneered by Anna Atkins<\/strong>, a botanist and photographer, who published a book, considered the first book in history with photographic images.Since then the technique has remained virtually unchanged: easy, inexpensive and always amazing<\/strong>.<\/p>\n\n

\n\n

Where can it be applied? <\/strong><\/h2>\n\n

This technique is mainly done on paper <\/strong>or fabric<\/strong>, with negative prints or simple objects.The paper must be thick and strong, because after the printing process it will have to be immersed in water. The fabric, on the other hand, must be light-colored cotton <\/strong>or linen <\/strong>. It is also possible to experiment with rendering on other materials such as leather, wood, ceramics or any porous natural surface that can be immersed in water.<\/p>\n\n

What you need<\/strong><\/h2>\n\n

As a first step, remember to cover your work surface, use utensils or containers you don’t use for food, and wear an apron and gloves.Our CIANOTIPIA KITS<\/a> already contain everything you need; you won’t have to worry about anything except getting the items you need to use and a frame if you perform technique with negative printing.<\/p>\n\n
