It's not often you get to photograph dusk over your own country and then, scant hours later, dawn over the Pacific. But here's the tricky bit, right? The first image shows dusk on 23rd June 2010 and the next one shows dawn on - that's right, the same day!
The shot above was taken a couple of hours into the long haul from Sydney to San Francisco aboard a United Boeing 747. Then some hours later, I gazed through my window as I tried to sleep - and sat there transfixed by the colours that began to develop on the horizon, from my vantage point more than 30,000 feet up.
I was really tired, but I got to my feet, walked back a couple of rows, took my camera from the overhead locker - and then made my way to the rear of the plane, to shoot some frames through the tiny observation porthole in the last emergency door.
It was well worth the effort. I can now claim to have photographed dawn AFTER shooting dusk on the same day.
