Understanding Cyanotype

What is Cyanotype?

Cyanotype is a photographic printing process that produces a cyan-blue print. It was developed in the mid-19th century by Sir John Herschel, a British scientist. The process involves coating a surface with a light-sensitive solution containing iron salts. When this solution is exposed to ultraviolet light, it undergoes a chemical reaction, resulting in the characteristic blue color.

Cyanotype prints have a unique and ethereal quality, making them a popular choice among artists and photographers. The blue hue, reminiscent of the cyan color, gives the prints a dreamlike and nostalgic feel.

The History of Cyanotype

The history of cyanotype can be traced back to the early 19th century when Sir John Herschel was experimenting with light-sensitive chemicals. He discovered that by coating paper with a mixture of iron salts, specifically ferric ammonium citrate and potassium ferricyanide, and exposing it to sunlight, he could create a blue print.

Herschel's invention was initially used for creating blueprints of architectural and engineering drawings, hence the term "blueprint." However, it was later embraced by artists and photographers for its artistic potential.

In the 19th and early 20th centuries, cyanotype was a popular method for reproducing photographs and scientific illustrations. Its use declined with the advent of more advanced printing techniques but experienced a resurgence in the late 20th century as alternative photographic processes gained popularity.

Today, cyanotype is not only cherished for its historical significance but also valued for its aesthetic appeal. Artists and photographers continue to explore and experiment with this versatile and captivating printing process.

Choosing the Right Paper

When it comes to cyanotype printing, selecting the right paper is crucial for achieving the best results. The paper you choose should have a smooth and even surface, as this will ensure that the sensitizer solution spreads evenly across the paper, resulting in a crisp and clear image.

Opt for a paper that is specifically designed for alternative photographic processes like cyanotype. These papers are typically coated with a light-sensitive emulsion that is receptive to the cyanotype process. Look for papers that are labeled as "cyanotype-ready" or "alternative process paper" to ensure optimal results.

Applying the Sensitizer Solution

Once you have chosen the right paper, it's time to prepare the sensitizer solution. The sensitizer solution is a combination of two chemicals: ferric ammonium citrate and potassium ferricyanide. When these chemicals are mixed together, they form a light-sensitive compound that reacts to UV light and creates the characteristic Prussian blue color of cyanotype prints.

To apply the sensitizer solution to the paper, you will need a brush or foam roller. Begin by mixing equal parts of the ferric ammonium citrate and potassium ferricyanide in separate containers. Then, using a brush or roller, apply an even coat of the sensitizer solution onto the paper. Make sure to cover the entire surface of the paper, ensuring that it is evenly coated.

After applying the sensitizer solution, allow the paper to dry completely in a dark room. This drying process is essential, as it allows the chemicals to fully absorb into the paper fibers. Once the paper is dry, it is ready to be exposed to UV light and developed into a cyanotype print.

Remember, the quality of your cyanotype print will depend on the paper you choose and how well you apply the sensitizer solution. Take your time in selecting the right paper and ensure that the sensitizer solution is evenly coated onto the paper surface. With careful attention to these steps, you will be well on your way to mastering the recipe for cyanotype prints.
