There is a similar reason for the flamingo’s pink appearance and also the high reflectivity of infrared light by their feathers as shown in the B&W version: the presence in their feathers of beta-carotene. Beta-carotene is present in both the algae and in the shrimp that are part of the flamingos’ diet. Beta carotene is an organic chemical that contains a reddish-orange pigment and is also highly reflective of IR radiation, explaining the light color of the flamingos’ feathers in the B&W image.<\/p>\n

The equipment was a Nikon D100, Tamron 17-50 f2.8 lens, Hoya R72 IR filter. Exposure under bright sunlight of 1\/30 sec at f2.8, ISO of 200.<\/p>\n
