Origins of Cyanotype

Cyanotype, also known as "blueprint" or "blueprint process," was invented in the 19th century by Sir John Herschel, a British astronomer and chemist. This technique was developed in response to the growing interest in reproducing diagrams and plans. However, it soon became an artistic expression in its own right.

What is Cyanotype?

Cyanotype is an alternative photographic process characterized by its distinctive cyan blue color. It is based on the sensitivity of certain iron salts to ultraviolet light. The magic of cyanotype lies in its simplicity and the beauty it can create from basic elements.

The Cyanotype Process

Key Ingredients

• Sensitized Paper: The paper is treated with a solution of iron salts, usually potassium ferricyanide and ammonium ferrocianide, which makes it sensitive to ultraviolet light.
• Negatives or Objects to Print: You can use photographic negatives or any opaque object to create your compositions.
• Ultraviolet Light: Exposure to ultraviolet light is essential for the process.
• Water for Rinsing: After exposure, a rinse in water is required to reveal the image.

Basic Steps

1. Paper Preparation: Apply the iron salt solution evenly on the paper and let it dry in the dark.
2. Place the Negative or Object: Place the negative or object on the prepared paper.
3. Exposure to Ultraviolet Light: Expose the setup to the sun or use a UV lamp for a set time. The light will activate the iron salts and you will begin to see the magical transformation process.
4. Rinse: After exposure, rinse the image in water. You will see the cyan blue gradually develop.
5. Drying: Let the image dry and admire your blue masterpiece.

Cyanotype in Contemporary Art

Although cyanotype had its roots in blueprint reproduction, today it is widely used by contemporary artists. Its unique aesthetic and artisanal process attract those seeking an authentic and distinctive form of expression.
