Course Description
The Cuprotype process is a fascinating nineteenth-century printing method that has recently reemerged, offering photographers a beautiful and accessible way to create richly toned prints using copper salts. Similar in ease of use to cyanotype, Cuprotype relies on ferric ammonium citrate as a light-sensitive catalyst, but produces a broader tonal range and an expanded palette of colors. Through chemical toning, prints can shift from buttery golds and warm coppers to delicate pinks, deep purples, and subtle neutral tones.
In this new online workshop, interdisciplinary artist and educator Anne Eder introduces you to the creative possibilities of this historic process and demonstrates how simple, affordable materials can produce striking results. The chemistry is inexpensive and easy to obtain, and photographers who already work with cyanotype may already have some of the necessary materials on hand.
Over four sessions, Anne guides you through each stage of the process. Together, we learn how to create digital negatives suitable for Cuprotype printing, mix and apply the sensitizer, coat paper, and determine proper exposure times. Anne also demonstrates how to clear and tone prints for both archival stability and expanded color possibilities.
As the workshop progresses, we explore the expressive qualities that make Cuprotype unique and are introduced to ferroblending techniques that further expand our creative options. Throughout the program, Anne presents the use of chemistry in a clear and approachable way, making this process accessible to both newcomers and experienced alternative process photographers.
By the end of the workshop, you leave with a solid understanding of the Cuprotype process, a collection of lovely finished prints, and the confidence to continue experimenting with its remarkable range of colors and tones. This online program is ideal for photographers interested in alternative processes, historical printing techniques, or discovering new ways to bring their images into the physical world.

What You Should Know:
You do not need a full darkroom for this workshop, but you will need access to a dimly lit space. A complete materials list will be provided once the course is confirmed.
Participants are expected to properly dispose of all copper-containing chemicals, as copper is toxic to aquatic life and should never be poured down the drain.
