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 beginner class led by Mary Louise Ravese of Bella Vista Photography, participants will use plant clippings from the JC Raulston Arboretum garden or items they bring from home to make cyanotype photograms aka sun prints. Ravese 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 must be rinsed in a water bath and left to dry. 

The chemicals used for this process include ferric ammonium citrate, potassium ferricyanide and hydrogen peroxide. They are safe to use but avoid ingestion, inhalation and contact with skin.

• Two trays or flat plastic container at least 3 inches deep and big enough to easily hold an 8.5 × 11 sheet with space all around.

• Gloves (like for dishwashing)
• Objects to use in your prin that fit on 8.5 × 11 sheet (optional).
