In the Twilight Zone - a photo on Flickriver

            I shot today’s photo last Monday night, 13th November, at 9:05 pm, seventeen minutes before the beginning of astronomical twilight*. Shooting then meant there was still sunlight refracting in the Earth’s atmosphere to make the sky bright enough to silhouette the horizon but not so much that the stars, dust and gas formations in the Milky Way couldn’t be seen. I planned to shoot this scene with the windmill being much more prominent in the foreground, but a barbed wire fence, lots of long and spiky grass and wheat, and a drainage ditch kept me from getting close enough to the structure to do so.

* Did you know there are three twilight periods, both after the Sun sets and before it rises? At sunset, “Civil twilight” begins, and the sky gradually darkens but is still bright enough for us to see without artificial lights such as headlights, streetlights, etc. Astronomers regard civil twilight as when the Sun is just below the horizon to when its centre is six degrees below the horizon. 

“Nautical twilight” occurs when the Sun is between six and twelve degrees below the horizon following sunset or between twelve and six degrees below the horizon before sunrise. “Astronomical twilight”–my favourite kind of twilight–begins when the Sun is from twelve to eighteen degrees below the horizon after sunset or between eighteen and twelve degrees before sunrise.

Captured north of Young, NSW, Australia, I shot this scene with a Canon EOS 6D Mk II camera and a Sigma 35mm f/1.4 Art lens @ f/1.8, using an exposure time of 8.0 seconds @ ISO 3200.
