Some months ago, I was interested in a creek formed by the falls in Yosemite. The dense foliage created interesting light effects and the overall darkness suggested it would be good subject for my first use of a black surface, the Richeson Premium Pastel Surface on Gatorboard. I spent about 45 minutes on it, proving to myself that a dark scene like this would would let me concentrate mainly on the highlights with a few middle values, letting the black surface remain untouched. I was amazed by how fast it became a believable representation of the scene. (Left, Below the Falls I, 9x12 pastel, © Bill Canright.)

A few days later I tackled a much larger version on a white surface (Richeson Premium Pastel Surface, Hardboard) with a split underpainting, using a light turquoise for the top half and a green/brown for the bottom half. Underpaintings can be created in a number of ways, from a complex drawing and color layer to a single tone of color on the surface. I like to do simple shapes, or as in this case, use just a couple of colors.

It proved the rule, "never try to paint something if you don't know what it is." You'll either make up something based on a subject you know well, or paint something stupid looking. Eventually, toward the end of the second full day I eliminated the whole problem with a placid pool of water. By providing the eye with a quiet place to rest it actually improved the overly busy scene. (Left, Below the Falls III, 20x16 pastel, © Bill Canright.)
Looking at the three together, it's interesting to see the similarities and the differences.
