Windmill Photobombing Crepuscular Sky
This Crown Sky during mid-civil twilight (about 15 minutes after the sun went down that night) is a pretty rare sky event. I’ve only been able to photograph a half dozen crown skies this good in 30 years. This is the second from mid -twilight with the sun well below the horizon by a few sun diameters by the time this was taken.
It was dark. I didn’t enhance the colors, this is a time exposure of about 3 seconds which tends to enrich colors a bit. I adjusted them to where I remembered them. This is a night sky after all… I will work a “promising” sunset from early Golden Hour to late Civil Twilight. Longer if the sky show lasts longer. Reverse that for morning / sunrise. Sometimes I work from my yard, other times I’m way out in the backcountry. Hard to know what the skies are going to do.
Science Musings:
The light rays reaching toward the heavens. Scientists call them Crepuscular Rays. Those photons bounce off ice in the atmosphere. The travel to my camera lens. Within the camera’s sensor, they are dutifully recoded but only as a series of 1’s and 0’s. All by the computer in the camera. There a variety of software programs (filters if you will) effect the digital signal in various ways determined by a programmer overseas. If you select automatic, those are the guys doing the camera adjustments not you. . Try manual mode sometimes…… You do the work…. Only three main things to learn….. Just saying.
