I don't like painting when the temperature is below50 degrees, but we recently had a warming trend and I was able to get out and spend 90 minutes developing an 8" x 10" plein air sketch. I made sure to work close to the back of my car with all my supplies close at hand, and I positioned myself in the warm sunlight so my fingers wouldn't freeze.
My objective was to capture the range of values and colors in the scene, balancing the dark shapes of the evergreen trees with the light stand of trees and sweeping snow formations. I didn't add a lot of detail because I just wanted a sketch I could later use for a more carefully considered studio painting.
In addition to painting this scene of FDR State Park in Yorktown Heights, New York, I painted two winter scenes based on memories established during trips along the Taconic Parkway on an 8" x 10" Gessobord panel.
