I recently bought Susan Sarback's book "Capturing Radiant Light in Oil" and tried the demonstration that she did in the book. I love her impressionistic style of painting and tried to capture the light as she does. It does somewhat look like the demo although I am not quite there yet. This way of painting starts out by blocking in the main shapes with whatever color you like, keeping the lights with warm colors and the darks and shadows with cool colors. After the 1st step you keep adding colors, mixing only on the painting, until you get the color you want, adjusting the value as needed by adding white. You do all of this using a pallet knife, just to add to the difficulty. This little painting took me around 3 hours. I do not have the skill yet with the knife but I think it will come more naturally as I work with it more.
