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.
As the beams of sunlight lit the clouds, it looked like the rainbow was on fire.
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!
As the setting Sun broke through clouds it created a rainbow over my backyard.
I see lots of fine sky phenomena right from my back deck. Such was the case last evening as a storm retreated east as they typically do. Clearing skies in the west allowed the Sun to shine through, the perfect combination for a rainbow.
For the main image above I shot the double rainbow with the ultra-wide 14mm Rokinon lens …
… and also with the 8mm Sigma fish-eye lens for this image. It’s angled to be suitable for re-projection in a tilt-dome planetarium theatre.
We’re into stormy spring weather here in Alberta, so there will be many more rainbows to follow the dark clouds. Let’s hope for no more floods like last June.
For many of us on board the spvStar Flyer, last Sunday’s eclipse on the Atlantic Ocean will be remembered as much for the rainbows as for the eclipse.
The main image above shows the spectacular and classic double rainbow that appeared before the partial phases began, demonstrating the rain showers and unsettled weather we passed through on eclipse day.
The low rainbow shown here appeared well into the partial phase, with 60 to 70 % of the Sun covered, so the source of light is considerably smaller than usual for a rainbow. You can see multiple bands of colour on the inner edge of the inner bow. Seeing this appear and rushing over to shoot it was another exciting moment in a hectic morning of roller coaster emotions. As this bow appeared, the light was beginning to drop rapidly toward the final spectacle of totality.
