Cyanotype is a photographic process that has captivated the imagination of artists, scientists, and craft enthusiasts for nearly two centuries. Its signature blue hues - rich, vibrant, and instantly recognisable- have adorned everything from botanical illustrations to contemporary wall art. While cyanotype originated as a scientific tool, it has undergone a remarkable revival in the modern art world, appealing to both DIY enthusiasts and professional artists. In this article, we delve into the fascinating history of cyanotype, its distinctive process, and its enduring appeal within today’s creative community.
The Origins of Cyanotype
Cyanotype was invented in 1842 by Sir John Herschel, a British astronomer and scientist best known for his contributions to astronomy and mathematics. Herschel was exploring ways to reproduce documents and images using a light-sensitive process. The cyanotype method relied on a simple chemical reaction: when paper coated with a solution of ferric ammonium citrate and potassium ferricyanide was exposed to sunlight, it turned a vibrant blue. The resulting image, known as a “blueprint,” was both striking and durable.
While Herschel developed the process, it was Anna Atkins, an English botanist, who popularised cyanotype in a way that would leave a lasting legacy. Atkins is often celebrated as the first female photographer. She used cyanotype to create detailed photographic records of plant specimens, producing stunning cyan-blue images that were both scientifically valuable and visually captivating. Her 1843 book, Photographs of British Algae: Cyanotype Impressions, is considered the first book illustrated with photographic images.
Cyanotype became a favourite among scientists and engineers in the 19th century due to its affordability and ease of use. Unlike the complex silver-based photographic processes of the time, cyanotype required relatively simple materials and no darkroom facilities. Engineers used it to reproduce technical drawings and schematics - hence the term “blueprint,” which still survives in modern architectural and engineering language.
How Cyanotype Works
At its core, cyanotype is a simple yet elegant chemical process. It involves two main components:
- Ferric ammonium citrate
- Potassium ferricyanide
These chemicals are combined to create a light-sensitive solution. Paper, fabric, or other porous surfaces are coated with the solution in a dimly lit room, then allowed to dry in the dark. The coated material becomes sensitive to ultraviolet (UV) light, which can be emitted by sunlight or UV lamps.
Once exposed, the UV light reduces the iron(III) ions in the ferric ammonium citrate to iron(II) ions. These ions then react with the ferricyanide to form insoluble Prussian blue, giving cyanotype its distinctive deep blue colour. After exposure, the print is rinsed with water to wash away unreacted chemicals, leaving behind a permanent blue image.
One of the appealing aspects of cyanotype is its versatility. Artists can create photograms by placing objects directly onto coated paper, use digital negatives to transfer photographs, or experiment with stencils and masks. The process is non-toxic, making it accessible to hobbyists and classrooms, and allows for endless experimentation with surfaces, textures, and compositions.
Cyanotype in the 20th Century
After its initial popularity, cyanotype experienced a decline in the 20th century as silver-based photography became the dominant medium. Despite this, the medium never disappeared entirely. A small but dedicated community of alternative process photographers kept the technique alive, often experimenting with hand-crafted papers and non-traditional substrates.
Artists in this period appreciated cyanotype for its unique aesthetic qualities. Unlike standard black-and-white or colour photography, cyanotype offered a singular, painterly blue that could not be replicated with other photographic methods. Photographers began to explore creative applications, from abstract photograms to mixed-media collages, blending cyanotype prints with drawing, painting, and other experimental techniques.
While cyanotype was less commercially significant in the 20th century, it became a symbol of artistic experimentation and DIY ethos, paving the way for its resurgence in the modern craft and art world.
The Contemporary Revival of Cyanotype
Today, cyanotype is experiencing a renaissance, fuelled by both artists and craft enthusiasts. Its accessibility, affordability, and striking aesthetic make it ideal for creative experimentation. Modern practitioners are not limited to paper; fabrics, wood, glass, and even ceramics can now be transformed using cyanotype techniques.
The process is particularly popular in DIY and craft communities. Hobbyists use it to create custom fabric prints, wall art, personalised stationery, and even home décor items. Workshops, online tutorials, and social media content have made the technique more approachable than ever, inspiring a new generation to explore the process.
Contemporary artists are also pushing the boundaries of the cyanotype process. Many combine it with digital photography, stencils, and botanical elements to produce intricate and imaginative works. Some even integrate cyanotype into mixed-media pieces, layering it with paint, ink, or collage to create dynamic, multidimensional artworks.
The revival of cyanotype is also part of a broader interest in sustainable and low-impact art practices. The process uses relatively benign chemicals and can incorporate natural materials, making it an appealing option for eco-conscious artists and crafters.
Cyanotype as a Tool for Creativity
One of the most exciting aspects of cyanotype today is its versatility as a medium for creative expression. DIY artists often explore unconventional surfaces and formats:
- Custom fabrics: Scarves, tote bags, and clothing can be transformed into wearable art.
- Wall art and home décor: Cyanotype prints make striking framed pieces, lampshades, or wall panels.
- Stationery and gifts: Cards, bookmarks, and personalised gift wraps gain a unique touch from the deep blue imagery.
Cyanotype can also be integrated with other crafts. Artists combine it with painting, embroidery, sewing, or collage to create one-of-a-kind pieces. The process encourages experimentation, allowing artists and hobbyists to discover new textures, layering techniques, and visual effects.
For those interested in sustainability, cyanotype presents a low-impact option. Many crafters reuse materials, work with natural fibres, and limit chemical waste, aligning the process with environmentally friendly creative practices.
Getting Started with Cyanotype
For beginners, cyanotype is an accessible and rewarding craft. A basic starter kit includes the light-sensitive chemicals, paper or fabric, and a UV light source - sunlight works perfectly on bright days. Objects like leaves, lace, or even household items can be used to create photograms, or digital negatives can be printed and transferred onto coated surfaces.
Experimentation is key. Different exposure times, layering techniques, and substrates yield unique results. Over time, crafters develop their own style and methods, making each cyanotype project entirely personal.
Conclusion
From its origins in scientific documentation to its current role as a versatile creative medium, cyanotype has proven to be enduringly captivating. Its vibrant blue tones, accessibility, and adaptability continue to inspire artists, hobbyists, and DIY enthusiasts alike.
Whether you are an aspiring artist, a craft hobbyist, or simply curious about historical photographic processes, cyanotype offers an opportunity to combine creativity, experimentation, and a touch of history. With just a few materials and some sunlight, anyone can explore this timeless art form and create stunning, uniquely personal pieces.
