Direct and Indirect Tonal Painting

This course covers

  • Theory of representing form and light tonally - tonal scale, edges, shadow shapes
  • Direct tonal painting in Oil Paint
  • Methods of Indirect, layered oil painting 
  • "Wipe out", Grissaile and acrylic underpainting methods

Below, from Left: An example of "wipe out" underpainting, and three different approaches to the depiction of a subject - a form drawing (pencil) , wipe out underpainting (one dark neutral, in this case raw umber), and grisaille  (in this case raw umber and white).  An acrylic grisaille of a figure modelled with very clear separation of tonal regions, ie the edges of each area is completely unblended.

Below: The process of one of my still life paintings using a wipeout underpainting in several dark neutral paints


Below: One of Scott's students learning a process of transferring from a full size drawing (technically called a cartoon) to a painting via an acrylic grisaille on a mid toned panel, overpainted in oil paint.

Below: famous examples of grisaille and cartoons, from left:

Andrea del Sarto grisaille "Baptism of the Multitude" in the Cloister of the Scalzo.
