A detailed watercolor study of some river boulders and rocks inspired by some reference photographs I took. The streams and rivers in the foothills and mountains of Upstate SC are full of these and they make great subjects. The tree was masked before painting. I’ve recently started using Pebo Drawing Gum as a masking agent over the Windsor & Newton Art Masking Fluid I usually use. Pebo has been recommended by a number of other professionals that I admire so I decided to try it. I’ve not noticed a lot of difference yet so we’ll see over the next few watercolors.
