I like moving the camera during the exposure. These holiday lights decorate a parking lot at a catering hall I was at a few nights ago. I made a couple of straight exposures and then I made this one. I processed it with Photomatix Tone Mapping program. The added contrast help make the blurred orange lights look like scratches...or I've been looking at this too long and it looks nothing like scratches.
I used the Canon G10.
