A second of my infrared enamels. An hour or so before taking this infrared picture, you would have seen the reeds at the back in the warm yellows and the water in the canal in the cooler blues and purples. Within an hour of dusk the relative heat of the two had switched, and the canal became this artery of gold. The heat from the bodies of the bats flying low over the canal can be seen reflecting in the waters’ surface, while the white projectile, swimming swiftly from right to left, close to the reeds turned out to be an otter.
