I shot this time lapse on a recent trip to my parents’ place in Central Pennsylvania. Living in Philadelphia, I never see this kind of sky. We have so much light pollution that it would be impossible to get this kind of shot.
This was shot over a 5-hour period with the Canon 7D using an intervelometer set for repeated 30 second exposures. I just let the thing run overnight and by 6am the battery was dead. Huge bummer because it was just starting to get light outside. I’ll have to try it again sometime now that I have a better grasp of what I’m doing.
