Online Class: Tools & Techniques for Tonal Drawing
Registration required. Space is limited. Please email contact@gokm.org or call 505-946-1000 for assistance with registration.
Inspired by the subtle yet dramatic tonal blends found in Georgia O’Keeffe’s art, this beginning-to-intermediate-level class will help build the essential skills needed to create tonal drawings with soft gradients and strong value contrasts using graphite pencils and charcoal.
The lesson will begin with a live demonstration by teaching artist Sudeshna Sengupta that shows how to build a value scale using various drawing tools and techniques. While learning to develop graduated blends of tonal values in this exercise, participants will also learn the compositional principles of gradation, which will be used to create spatial depth and dimension within the pictorial space.
