The causeway to Mutton Island is part of my daily morning walk. On clear sunny mornings, the railing reflect the golden light of the rising sun.
The bars of the railing aren’t really as close as the picture above implies – the effect is caused by using a zoom lens with a very large focal length. The image below shows a more normal view of the railings, about 45 minutes later. This article by Nikon explains it well (as it happens, the photos were taken with a Nikon camera).
