We camp a lot! We even have a full time camp-site at Goose Island and spend as much time as possible there. And we have a lot of campfires usually shared with groups of friends. And I take lots of pictures. My Sony Cybershot takes great shots at night, especially around the fire. On Sunday the 27th I took the picture below. Out of hundreds of night photos, I've never had one like this before.
There was no smoke from the fire and nobody near me was smoking, and yet this photo appears to have a smokey face... plus the very next photo of this group taken seconds later, was clear. What do you think it is?
