Can you see the UFO?
Last night I tried, not very successfully, to photograph some distant fireworks, but I got quiet a surprise when I viewed them on my computer, Can you see the destinctly disk shape object hovering in the upper left of the sky. You might have to enlarge the image by clicking on it. Didn't take long to figure it was a reflection of a hanging light behind me.
Moral:: Remember reflections when photograhing through glass, even when it us dark!
