Aurora Borealis over Lake Superior. This photo was taken from the shoreline at Union Bay Campground in the Porcupine Mountains State Park. An essentially moonless evening, and a few scattered clouds made viewing possible. I used the Canon 6D with the OM Zuiko 24/2.8 lens at F5.6 for this picture.
The critical lesson for shooting auroras is to use as short of a shutter speed as possible. Auroras are constantly moving and to get the structures, a shorter shutter speed is necessary.
