Perhaps the central question about [Eliot] Porter's work is about the relationship between science, aesthetics, and environmental politics. His brother, the painter and critic Fairfield Porter, wrote in a 1960 review of [Porter's] colour photographs: 'There is no subject and background, every corner is alive,' and this suggests what an ecological aesthetic might look like.
