This was the first time I saw (or managed to shoot) the elusive “green flash”, following a Gulf of Mexico sunset. I say “following”, because the sun is below the horizon; its light has been bent toward green/blue, as if through a prism, and bounced off an inversion to reach the eye and lens in a very fleeting manner. Read more about this fascinating phenomenon in my post on the second such instance I saw, a couple years later in Hawaii.
