In this project we had to paint the same scene four times, but under different lighting conditions each time. This is a scene from the street I live on seen from my garage. The four lighting conditions were upper left early morning to around noontime, upper right overcast sky, lower right foggy weather, and lower left mid-day clear sky.
Each scene took about 5 hours to paint. Each is 9x7 inches, painted in acrylic on Bristol board, mounted on illustration board. These are, if I remember correctly, my first paintings en plein air.
