Many artists copy the works of other artists to learn and practice technique. Most often these "master copies" are made from historical works, but here I copied from a present-day painter David Gray. His use of light and shadow is masterful here, using the full range from the brightest white to the darkest dark. His painting was in color but I did this copy in a monochrome using only burnt umber and white. With this painting I was learning and practicing a number of techniques, including blending oil paint with a new type of brush I hadn't used before, and working on combining hard and soft edges in the same work. I was also learning a three-layer technique where layer 1 blocks out shapes and basic values, layer 2 captures most of the value range and details with paint straight from the tube, and layer 3 completes the blending and details using a little linseed oil mixed with the paint.
