My process is the following. I begin with thumbnail sketches that explore possibilities regarding the general composition and various patterns of light and shadow. Once my idea regarding the composition has become clear, I choose the location, find a model, gather together props and costumes, set up the scene and lighting, and take reference photos. I usually also paint very simple color studies to evaluate the color scheme. Next, I stretch and tone the canvas a medium gray made of burnt umber, ultramarine blue, and white. After this, I paint a simple line drawing and two-value underpainting (i.e., the middle value of the areas in light, and the middle value of the areas in shadow) using an earth tone such as burnt umber that is thinned with painting medium. Finally, I add layers of increasingly refined value and color.
