Ok I am asuming that this is a bounce off of the UV filter, but since I have never seen a reflectin quite like this I thought I'd ask around.
This was taken at night in close to pitch black conditions @ ISO 200, 1/225, f4.0, with a 70-300mm lens set at 70mm. I used a flash gun for the strobe.
The reflection is of the street sign, and slightly down and to the left of it.
Got any clues?
