green flash
Yep, the green flash really exists and it isn't just in the eye of the beholder. It is the last band of the light spectrum projected by the light of the setting sun broken up by the prism of the atmosphere around the curvature of the earth. As the sun sets below the horizon the bands of light are projected like with a prism or rainbow. We see the green light for a split second, but not the others, because it is the last band to be shown and thus is visible when the sun itself has dropped just below the horizon. The other bands cannot be seen because the sun is still above the horizon, and thus obscuring them.
Notice that the ocean is a green color too, caused by that being the last bit of ambient light available to the camera. I shot this with my Rebel 300D and 70-300 Sigma over near Mile Marker 14.
