This month I've been photographing skies in preparation for my "Sky" workshop with Karen Margulis. It has been a good experience. I was surprised that I had not taken more time to study skies. The sky is truly a beautiful thing and it changes with the day, the light and the weather. Karen challenged us to paint the sky every day to better understand the colors and shadows in the sky. One exercise was to mix grey from three pastel colors - triad on the color wheel. Later when I added some of these grays to my sky, I was pleased with the richness it gave the painting. A great workshop - as usual from Karen.
