While teaching painting in Provincetown in the early 1900's
Charles Hawthorne had his students
paint models on the beach with their backs to the sun.
The mud-like color of the face in shadow
gave rise to the nickname "mud heads".
Mud Head Study #1
Mud Head Study #2
"The quality of a study was judged by the effectiveness with which
the light was suggested by simple shapes of color."
What an important lesson in values!
I'm going to incorporate an exercise on this
in my Figure in the Sunlight class at NRAS this summer.
