Making this long exposure (1.6 seconds) of Lake Louise in Alberta, Canada after sunset inspired me to read about the blue hour.
A scientist named Chappuis discovered that the ozone layer absorbs ultra violet light, and after sunset this Chappuis absorption has a significant effect on the color of the sky. I’m going to have to learn more about light wavelengths to understand this in depth.
As a photographer, I will remember the soft and soothing effect of this blue hour. Some artists enjoy photographing city scapes featuring yellow incandescent light during the blue hour. Have you tried it?
While the sun’s brilliant orb slipped behind the Grand Tetons, the clouds reflected the orange glow of sunset. That evening the clouds took on a rippled texture as well as a misty, ethereal quality. We could feel the temperature fall. The light show was brief. Soon it would be dark.
Last evening I went down to the beach to watch the sunset, and nearly an hour after the sunset the sky gave me a gift. Two bright blue light beams cut through the rosy western sky and they lingered for about 15 minutes, giving me plenty of time to pause my dinner, steady my camera on the railing and take a half second exposure of this special scene.
I guessed that the blue rays were caused by clouds beyond the horizon blocking the rosy twilight, and my photography mentor Gary Hart said he thought that was the case. Today, I had another thought about this unusual sight.
These are tough days for our family, as my father’s health is in rapid decline and our hearts are heavy, knowing he will leave us any day now. I just witnessed stunning light beams from beyond the horizon. There could be a message of comfort and hope from a place beyond my sight. I believe so.
