I painted this from a photo that one of my watercolor students took on a trip to Maine. When painting a window from a photograph, the artist must be careful not to copy the photo! Often photographs show windows as blank black spaces and this was no exception. The last thing I wanted was to have a big black "hole" in the middle of my painting.
Painting reflections of sky and trees on the windowpanes takes care of that problem and makes the window come alive!
