Details:
Lightning bolts and a rainbow at sunset in a thunderstorm retreating over the Alberta prairie, July 18, 2016. There is a faint outer bow visible at left.
Catching lightning in still frames is tricky, especially when the sky is still bright. Better to shoot video at 30 frames per second and you are bound to catch some bolts. I did tonight, July 18, as a major storm rumbled over southern Alberta.
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 using an ND filter to further extend the exposure time, but my timing would have had to have been very, very lucky!
As the storm receded the sunlight grew more intense from the setting Sun and created a fabulous double rainbow across the reddening sky.
