This is an amazing timelapse video by James Leng.
On my night time flight back to SF from Amsterdam, I noticed that the lights from cities were making the clouds glow. Really spectacular and ethereal – it was really seeing the impact of urban environments from a different perspective. Each glow or squiggle represents one town or city!
Luckily the flight was half empty, so I was able to set up a impromptu mound made up of my bags, pillows, and blankets for my camera to sit on.
We were around the midwest at the beginning of the clip, and there were fewer cities once we hit the rockies. the bridge at the end is the san mateo bridge.
Technique: 1600iso; beginning – 1 (30sec) exposure / 45secs, end – 1 (4sec) exposure / 10 secs; total elapsed time: around 3 hours?
