by This painting is called ‘The Woman with a Pearl Necklace” by Johannes Vermeer. It appears that this was lit during mid day given the white lighting. The only key light was through the window, with a fill light on her back due to the light bouncing off the white walls. I have made the assumption that the only light source is through the window because everything below her waist is dark. The way the painting is composed makes me feel that the subject is preparing for an important occasion.
