From Lavas To Wagtails

natural color image (left) and color enhancement (right) processing by Henrik Bondo, Denmark

Inspired by yesterday's LPOD that we should get medical researchers to figure out how to enhance our color vision, although ordinary Earth scenes might be unbearably garish… I tried the same technique, as I have done earlier with the Moon to enhance colors (in PhotoShop: Saturation 25%, repeated five times). These photos taken out of our window towards the little pond shows a wagtail, who uses a large part of each day to hunt for delicious insects living at the pond. The feathers of the wagtail are really black-grey-white in striking contrasts (left photo). The right photo - the result of forefront medical research - shows simply the colors of greedy hunger. One can clearly see how the greed in the eyes of the wagtail, looking for more food, transforms the surroundings to a vibrating, intensely colored landscape, and how the greed even gives a fine reddish hue to specific hunting-relevant areas of this otherwise absolutely black and white wagtail: The outer part of the wings and upper lip.

Note from Chuck: This is a lovely experiment that demonstrates how supersaturation can bring out color variations too subtle to be seen otherwise. I wonder if wagtails or other animals in their environment can detect the reddish hue, and if it has a significance?
