I took this shot using my iPhone 6s plus on the penultimate run on my last day skiing at Courmayeur, Italy this week. Only when I got home did I spot the small vivid blue light streaming through the trees and was reminded of the description of the White Walker's eyes as a 'blue that burned like ice'.
I took the shot directly into sunlight giving the surrounding scene an almost monochromic feel hence I was taken aback by that blue light.
