Rainbows, Lightning, and Sunsets, Oh My!


The sky presented a pyrotechnic display of light and colour in the sunset sky.

What a show tonight, July 18, as a thunderstorm lit the sky with bolts of lightning. As the storm retreated, the Sun broke through, ideal lighting for a rainbow. In this case I was able to capture the rainbow pierced by bolts of lightning. See below for tech details.

A little later, the sunlight got stronger and the rainbow grew to span the sky, in a beautiful display of a double rainbow lit by the red light of the setting Sun.

Double Rainbow at Sunset

A double rainbow at sunset on July 18, 2016 after a pyrotechnic thunderstorm. The low Sun is providing the red lighting, with some shafts of sunlight and shadow converging to the anti-solar point. This is a 2-frame panorama with the 16-35mm lens at 16mm, stitched with Adobe Camera Raw.

As the beams of sunlight lit the clouds, it looked like the rainbow was on fire.

Fiery Rainbow at Sunset

It has been a stormy start to summer in Alberta, but at times the sky has put on a stunning show. That was certainly the case tonight.

Technical on the Lightning and Rainbow shot at top:

This is a stack of 35 consecutive video frames taken with HD (1920 x 1080) resolution at 30 frames per second with the Canon 6D, and extracted as an image sequence with Photoshop, then processed in Adobe Camera Raw, then stacked with Russell Brown’s Stack-A-Matic into a smart object with maximum stack mode, to accumulate the frames taken over about 1 second into one still frame.

So I could have got this with a single 1-second exposure with the lens stopped way down and a ND filter, but my timing would have had to have been very, very lucky!
