Aurora borealis reflects in the Koyukuk river, Alaska. Canon 5D mark II, 24mm f1/4L II, 30 secs @ f1.4, ISO 1250
The arctic photo tour I’m guiding was off to a good start on the first evening as clear skies eventually revealed some aurora activity. What was particularly interesting about the display was not it’s brightness but rather the color reflection in the Koyukuk river. It’s been a busy few days and hopes are high for some polar bear photography.
