9x12 pastel on Art Spectrum Colorfix, black
I just finished a wonderful workshop with Robert Carsten put on by the Pastel Society of New Hampshire. Robert is an excellent teacher, generous with his ideas. The first day he demonstrated on black paper using a dry underpainting technique. He chose a light and a dark of the three primaries for this and blocked in his basic shapes being true to his values. I had never seen an underpainting done like this and even though I don't usually use black I had to give his method a try. I am pleased with the result.
