The blue tint in this picture suggests it was taken with the sun hanging low in the sky, but it wasn’t. The reason for the blue hue is that the shadow cast over the boat and surroundings. I don’t know what it is with shadows that makes snow and ice look blue (anybody who knows is welcome to explain), but it always happens. Had I shot this picture in the evening, I think the blue tint would have been too intense. Am I right?
