That's what happens when you take a picture of snow falling with a flash. Believe me, I've taken pictures that look like that many times before.
My camera isn't build for taking night pictures without flash. I tried it and the whole picture's just black with exception of the part where the street lamps are, but even that part is very dark.I have a Nikon Coolpix S8000
Looks shopped
What I like most in the picture is that it isn't edited at all (resized but nothing else).
