The Painter's Keys at http://painterskeys.com/ has been a wonderful resource over the years ... and continues to be. Robert used my letter in the last issue of his excellent newsletter available at http://clicks.robertgenn.com/perfect-happiness.php#515 I find that his writings very often hit a chord with me. Artists apparently follow similar paths. I hope you sign up for his free newsletters and enjoy them as much as I do.
Sorry that I am not painting for a couple of weeks. Meteorology and family sometimes takes precedence... and that's OK. The oils will start to fly again in November. If you want to see the meteorology that I do, visit COMET at http://www.comet.ucar.edu/ You can register for free and learn more about the environment than you ever dreamt was possible. I have many modules on Satellite Meteorology (The Satellite Palette) and also lots of information on Performance Measurement...
