Photograph of the day - Butterflies

Gingee Fort is a paradise for butterflies lovers. This photo is taken on the citadel of the Fort where this butterfly was resting on a flower near the edge of a cliff, just away from the strong breeze coming over from the valley below. The flower is not visible in the photograph. I, as a fluid mechanics lover, would like to say that the butterfly was resting inside the boudary layer where the flow was pleasingly laminar and was just next to still; whereas the turbulent air current was flowing above my head (and that of the butterfly too!). I must compliment the butterfly as it behaved extremely well during the shoot-out that lasted some fifteen minutes.

Camera: Canon Powershot A80
Exposure: 1/400 s, f/2.8, +0.3 step correction, ISO 100
