Whenever you're taking pictures out in the cold and they come out foggy, condensation is usually the explanation.
Still I think it’s too angular and I’d expect similar effect in other photos taken in very short time span and in the same conditions.
As you can see, I’m not letting my Spirit of Winter condense into nothing special.
I wish I'd catch similar anomaly again, it's easier to tell something sensible from more than just one example.
