On my recent trip to the Carnegie I noticed these two paintings in the same room. Content aside I could not help but observe that both used back-lit figures although the first painting is lit very well and the second is lit very poorly. I find it helpful to make these simple comparisons so if I need to use a similar lighting situation I can refer to this clear dichotomy of quality.
