Instructor: Mary Louise Ravese

Skill Level: Beginner to Intermediate

Cyanotype is a simple photographic printing process that creates an archival blue and white print. The cyanotype process was invented in the 1840s and is easy and inexpensive to do at home.

In this class, we’ll use plant clippings or other items you bring from home, to make cyanotype photograms aka sun prints. Students with more experience will go beyond simple cyanotype photograms to experiment with some “embellishment” techniques using things like turmeric, salt, vinegar, and soap bubbles to add additional color and texture to the one-of-a-kind cyanotype pieces.

Mary Louise will explain how to make botanical “photograms” – direct contact prints of plants placed on sensitized cotton material and then exposed to sunlight. The developed print is then rinsed in a water bath and then left to dry. The final print will have a blue background and no color where the object touched the material or left a shadow on the material. So, this process is a great way to celebrate the shape of things.

No camera is needed for this process!

The chemicals involved include ferric ammonium citrate, potassium ferricyanide, and hydrogen peroxide. They are safe to use, but care should always be taken to avoid ingestion, inhalation, and contact with skin.

Students should bring the following to class:

2 Gallons of distilled water
Garden shears
Found objects or plant clippings for making prints
Toothbrush and small / pastry-size brush for splattering
Bagged lunch

All other materials will be provided.

Please note that this class will take place at the Hattie Weselyk Studio at 113 Lutece Circle, Kennett Square, PA. The class will take place primarily outdoors with a rain date of Sunday, September 24 if there is rain forecasted for September 23.
