Underpainting in Oil - the optical grisaille
UNDERPAINTING - the optical grisaille
The purpose of an underpainting is to establish the composition and overall light/dark pattern while initiating the development of volumes and substance to the forms. An underpainting allows you to envision the totality of the pictorial idea. In addition to correcting drawing errors the underpainting’s primary purpose is to fix the all important Notan, which is the Japanese term for light/dark harmony.
