Sydney, as seen from my balcony five minutes before ‘lights out’ in Earth Hour 2009, with the camera set up to take what it believed was a +0EV shot:
Exact same exposure, aperture, ISO and perspective (except for somebody nudging the tripod) as previous shot, after all the lights that were going to go out had gone out:
Half an hour after the lights came back on:
(Note for keen observers: on top of the bridge there are two flags. The one on the right is a special “Earth Hour” promotional flag. This flag remained illuminated throughout.)
Beautiful, great that you captured the moment with skill. Driving over the Harbour Bridge during Earth Hour had a rather eerie feel, like the city had been evacuated and someone had forgotten to pass on the memo.
Speaking from the opposite side of the harbour, I can say that it certainly didn't look a lot darker, and in fact Luna Park had all of the lights decorating the Coney Island building still on.
I wonder what the justification was for keeping some(or, as it seems from looking at those photos, most) lights on?
These shots are stunning!!
