Seastorm off Bundeena Cliffs in Royal National Park just south of Sydney Australia.
Taken using the brilliant Startrails Photoshop Action to blend 15 X 30sec identical exposures. You can download the Action from here:
If you view in Large mode you can see startrails between the clouds. Also the short horizontal light along the horizon is a fishing trawler.
Funnily enough there was an average of only one lightning bolt per exposure.
I’ve now photographed 5 storms off these cliffs and the really curious thing I’ve noticed is that the lightning always seems to concentrate in the same places – here and about another 45 degrees to the right along the horizon. I know now that if I set my camera up here or at the other angle I’m always going to get the best lightning shots – weird or what? I would have thought the lightning strikes would be much more random than that.
