Paintings can exert a strong effect on their viewers by creating atmospheres. But how is it possible for a painting to create an atmosphere? My goal in this paper is to provide a partial answer to this question by focusing on the depiction of light.

It is in virtue of this distinctive phenomenal (...) character that the depicted ambient light can make a significant contribution to the overall phenomenal character of the experienced atmosphere.
