Cyanotype and Sun Printing

Cyanotype and Sun Printing Training

The Cyanotype and Sun Printing certificate program is a comprehensive, hands-on course designed for photographers, artists, printmakers, and creative hobbyists who want to master the historic yet versatile process of cyanotype. You will learn to mix and apply the light-sensitive solution, create photograms using natural and found objects, expose prints with sunlight or UV sources, and develop rich Prussian blue images. The main practical outcome is the ability to independently produce a portfolio of finished cyanotype prints, troubleshoot common issues, and experiment with advanced techniques such as digital negatives, toning, and mixed-media applications.

The program follows a beginner-friendly progression that balances scientific theory with extensive studio practice. Starting with the chemistry and history of the process, you will move through solution preparation, paper selection, and coating methods, then explore exposure variables, washing, and oxidation. Core skill areas include chemical handling, exposure timing, image manipulation via digital negatives, and creative toning for color shifts. You will also learn to apply cyanotype on fabric and other surfaces, and combine it with other media. This program is ideal now because cyanotype has seen a resurgence in contemporary art, design, and even scientific illustration, offering a low-cost, non-toxic entry into alternative photography that connects analog craft with digital workflows.

What is Cyanotype and Sun Printing?

Cyanotype is a photographic printing process that produces a distinctive cyan-blue image using a light-sensitive solution of ferric ammonium citrate and potassium ferricyanide. The core concept involves coating a surface—typically paper or fabric—with the solution, exposing it to ultraviolet light (most commonly sunlight), and then washing it with water to develop the final blue print. Objects placed on the coated surface during exposure create white or lighter silhouettes, while areas exposed to light turn deep blue. This process, invented in 1842 by Sir John Herschel, is one of the earliest photographic techniques and remains popular for its simplicity, low toxicity, and striking aesthetic.

Today, cyanotype is experiencing a vibrant revival in both fine art and applied contexts. Artists use it for unique prints, photograms, and mixed-media works; designers incorporate it into textiles, home décor, and fashion; educators employ it as an accessible introduction to alternative photography and the science of light. Recent shifts include the integration of digital negatives for precise image control, experimentation with toning agents to shift the blue to other hues, and the use of cyanotype on non-traditional surfaces like wood, glass, and ceramics. Its relevance is also growing in the maker movement and sustainable art practices, as it requires only water for processing and relies on natural sunlight.

Mastering cyanotype builds a versatile skill stack that combines chemistry, exposure science, and artistic composition. Practitioners develop a keen understanding of light intensity, UV exposure timing, and the effects of different papers and fabrics on final image quality. They also gain proficiency in creating and manipulating digital negatives, which bridges analog and digital workflows. These skills are valuable for fine artists seeking a unique visual language, for photographers exploring alternative processes, for designers working with custom textiles, and for educators looking for a hands-on STEAM activity. Whether pursued as a personal creative outlet or integrated into a professional practice, cyanotype offers a tactile, rewarding way to create one-of-a-kind images with a rich historical lineage.
