Lightning bolt 2.
I have a question for any experts out there. Anyone with knowledge of lightning and atmospherics, and also anyone with working knowledge of camera sensors.
I took these two shots yesterday, more in hope than anything, Being lucky enough to have the Sony RX10 that shoots at 24 frames per second, I pointed at the sky across the street and held the shutter for a second. I got lucky and managed these two shots. Not very exciting looking, being daylight lightning shots, but I am intrigued by the difference in the two shots. They are consecutive frames 1/24th of a second apart. Bolt 1 shows up the brightest, and actually shows the lightning in its ground to air phase and the bolt is only half completed. Lightning bolt 2 shows the completed bolt all the way to the cloud, but is fading in brightness. The bolt itself was very close with barely a second elapsing between flash and the window rattling thunderclap!
My puzzle is the first shot that shows a purple halo around the upward end of the lightning, and a corresponding colour shift across the image in the sky below the top of the lightning.
I'd love to know is this just an issue with the sensor and its response to a sudden intense flash, or is it atmospheric?
My guess is the sensor, but I'd love to hear other opinions or experiences.
These two shots are both cropped heavily from the left half of the wide angle image, hence the slight distortion in the vertical lines of the house.
