Here is the oil painting of the Jefferson Memorial, it was all painted in plein air over three sessions between 10am and 1pm. The quality of light as it struck the marble structure and how the shadows were cast was really important to me, I wanted to capture the golden pink tones of the sunlight sides and the cool purple and greens of the shadows.
I am finding that painting buildings with oil paint is a much more challenging endeavor than working in watercolor. It all has to do with the finessing of edges, not getting to many hard edges except where it is important and also getting the perspective correct. I also wonder if working on a larger canvas would help, to have more room for the more fiddly details. Here is last year’s painting of a nearby view.
