Class Description

Description

Gum bichromate represents a beautiful and historic alternative photographic process, though it can present challenges due to the many variables involved in achieving successful prints. This intensive, hands-on, in-person workshop provides comprehensive coverage of materials, techniques, and methods for creating stunning full-color gum bichromate prints. Through detailed lectures, visual presentations, and live demonstrations, participants will be introduced to the fascinating historical development of gum bichromate printing as a photographic technique.

Digital Workflow and Preparation:

A major focus of the workshop involves understanding the complete digital workflow required for producing color-separated digital negatives. Students will examine in detail how to work with these components to create the foundation for multi-layer prints. Participants will gain hands-on experience in manipulating digital negatives to achieve optimal quality and visual results in their finished prints.

What You Will Create:

By completing this workshop, every student will produce at least one finished color gum bichromate print with a minimum of four layers. These layers will incorporate cyan, magenta, yellow, and black pigments, derived from three separate negatives. This multi-layer approach demonstrates the full complexity and potential of the medium.

Prior Experience:

Knowledge of Adobe Photoshop is advantageous and can enhance your learning experience, though it is not a requirement for participation. The instruction covers the necessary technical concepts for all skill levels.

Materials Fee: A material fee of $100 is included in the tuition cost, covering all supplies needed for the workshop.

We are not responsible for any non-refundable travel costs (such as airfare, train tickets or accommodation costs).
