8966 Shadows (Acrylic, 55 minute) From The Inspiration of Painting PBS television series, Jerry Yarnell demonstrates how to create convincing cast shadows and understand how light direction defines form and realism. Done on an 18" x 24" canvas - beginner level. While this lesson is shown in acrylics, the shadow concepts in 8966 Shadows translate beautifully to oil painting and watercolor too.
