Fogbow and Pack Ice, 80 degrees N.
We were hunting for polar bears - a distinct challenge in the intermittent fog. But the mist did give us one unexpected gift: a fogbow. Caused by the same phenomena that cause rainbows, fogbows are more diffused, and are typically colorless.
A wide-angle lens captured the fogbow, but I struggled to find a foreground to complete the composition. There were images where the ice was better "arranged", but on those the fogbow was broken or less pronounced. In the end, I settled on this one, which shows the arc beautifully, even if the ice is a little scraggly. Nature rarely performs precisely on cue.
