#159 Friday, Saturday, Sunday, 7/14-7/16 9am –4 pm

Instructor:  Ikumi Kayama 3 days  $390

Registration closes Friday, July 7

This 3-day workshop, aimed for illustrators who are familiar with basic medium for natural science illustration
(Graphite, pen/ink, watercolor), will expand their toolbox to include digital media. The single most common
mistake made by students is to forget everything they learned in art class and recreate the wheel in the
computer. This class will treat Photoshop as another tool. The foundation of good drawing, light on form,
composition, color theory, and storytelling will be emphasized and revisited throughout the class.
The class will focus on becoming familiar with the workspace and to select the tools most commonly used
by professional scientific illustrators. We will also cover common troubleshooting and how to avoid being
controlled by Photoshop. In the intermediate to advanced courses, the class will discuss different methods to
separate pixels and selections for efficiency and hidden yet useful tools.
