Cyanotype is one of the oldest photographic processes in existence. Invented by Sir John Herschel in 1842, it produces the characteristic Prussian blue images that generations of blueprints were built on. Anna Atkins used it to create the first photographically illustrated book in 1843. By rights, it should be a historical curiosity. Instead, cyanotype in 2026 is more widely practiced than at almost any point in the past century — and the reasons say something interesting about where photography and fine art printing are going.
Why Cyanotype Is Thriving
The process is remarkably accessible. The chemistry involves only two components — ferric ammonium citrate and potassium ferricyanide — that are inexpensive, relatively safe, and widely available. They are mixed in solution, coated onto paper or fabric, dried in the dark, exposed under UV light (sunlight works perfectly), and developed in plain water. No darkroom required. No enlarger. No specialized equipment beyond a contact frame or a sheet of glass.
That accessibility has made cyanotype a gateway process for photographers curious about the analog world, for artists exploring printmaking, and for educators teaching photographic history. But the revival goes beyond accessibility. The distinctive blue palette has genuine aesthetic appeal — not as a limitation but as a character. Many contemporary practitioners are making work that uses the blue not as a constraint to be worked around but as the central visual fact of the image.
Contemporary Practice
The contemporary cyanotype scene is diverse. Some practitioners work with photograms — laying objects directly on coated paper and exposing them to produce silhouettes. Others use large-format negatives, either film or inkjet-printed digital negatives on transparency film, to produce detailed contact prints. A growing number of artists are combining cyanotype with other processes — toning with tea or coffee to shift the blue toward brown or gray, layering cyanotype with platinum-palladium, or working on unconventional substrates like wood, stone, or textiles.
Archival Considerations
Cyanotype has a reputation for instability that is partially deserved and partially overstated. The blue is sensitive to alkaline environments and prolonged exposure to high humidity — matting and framing with acid-free materials is essential. However, well-processed cyanotypes stored correctly are not as fragile as their reputation suggests. Many 19th-century examples have survived in excellent condition. The key variables are processing completeness (insufficient washing leaves residual chemistry that accelerates fading), storage conditions, and display lighting.
Collecting Cyanotypes
For collectors, cyanotypes represent an interesting entry point into the alternative process market. Because the materials and process are accessible, the edition economics can be favorable — artists are often producing limited editions at price points below comparable silver gelatin or platinum-palladium work. The aesthetic is distinctive and the historical lineage is real. For collectors interested in contemporary work that engages seriously with photographic history, cyanotype deserves close attention.
