Storm Clouds 3/11/16

This was the view out my office window a few months ago, one nice and half stormy afternoon. I tried to enhance the sense of depth in the painting, fixing what the photo lost. The photos I took looked flat, and lost how the layers of clouds moved into the distance. Some parts were also messy in the photos, so I moved clouds around and took some out.

Here's the progression from sketch to finished painting. This painting was done with no medium in the bottom layers, so the paint would stay wet and be blendable all day. The top layers did need a little Neo Megilp medium added to give transparency to the color, and make very thin glazes possible. For instance the blue sky has a very thin layer of pure blue over it that makes the color more intense.

I found a new tool to use for the under drawing this time, watercolor pencils. Regular pencil smudges too much to be used under oil paint, because graphite is non-polar just like oil paint, so they're attracted to each other. But I like a detailed drawing to start from and pencil is a natural fit for that because it can be very precise, and faint enough to not show through the paint, unlike ink or charcoal.

Water-soluble graphite doesn't interact with oil paint, so the drawing stays put nicely. The drawing can be painted over with water too, and the color gets much darker. I tried that at first, in the top left corner of the painting, but it wasn't really helping so I didn't do it anywhere else.

Here's a little detail from the left side of the painting, showing the smudgy grey clouds in the front, cumulus clouds behind them, and the background layers of clouds.
