The light changes so much over the short course of a painting that a plein air painter can easily “lose the light” unless he or she has made a preliminary value sketch or shot a reference photograph. That certainly was the case on Christmas Day as I was painting a small camellia tree at Eden Gardens State Park, a short distance from my home in Point Washington, FL. I had set up my easel thinking the sun was going to move differently than it did. About halfway into my painting, I realized I was losing my light, so much so that the tree was becoming completely shadowed by the massive live oak behind me. I was challenged in the same way last week, painting the shops on the lake at Baytowne in Sandestin, Florida. Angular shadows move rapidly on structures as the sun slides around to the other side. In both cases, I had failed to make a values sketch or take a photo, in favor of jumping right into the painting. When will I learn, that delaying the gratification of painting for just a few minutes, by making that preliminary values sketch, makes painting so much easier!! My paintings were successful, but I struggled more than I otherwise would have. Below are the two oil paintings.
