Using Altitude and Azimuth Tables to Understand Light Shifts,

I had noticed for several months ago that the light and shadow on an object can change very suddenly and dramatically. This phenomenon was especially noticeable around 1:30 in the afternoon.

Everything worked fine until yesterday, when I was working in the morning and experienced the same sudden shift in lighting. I decided it was time to learn more about exactly how the sun tracks across the sky.

Recent Painting: Lion of Atlanta in Oakland Cemetery

I did this watercolor early in the morning about a week ago at Oakland Cemetery. Finding a shady spot in which to work was a challenge and forced me to work from a radical viewpoint, which made for some dramatic foreshortening. Overall, I was pleased with the result.

Plein Air Equipment

Keep your equipment and materials simple. Mobility is important, and you don’t want to have to spend 20 minutes getting everything set up. My plein air kit consists of:

  • 12 whole pans in a metal box
  • 1 1/2″ flat brush
  • Round kolinsky sable travel brushes: #6,#8,#10,#12.
  • Small, flat nylon brush for loosening paint.
  • Paper towels/kleenex
  • water bottle (I use a 1-quart nalgene bottle for backpackers.)
  • Small spray bottle with water
  • Pencil — usually an F or B hardness (with a cheap plastic sharpener)
  • Kneaded rubber eraser
  • Watercolor block, 12×16 is a convenient size for me.
  • Sketchbook
  • Sunscreen
  • Insect repellent
  • Floppy hat to keep the sun out of my eyes
