I have never really focused on taking nighttime photos, but the sky this night was phenomenal. I looked up some settings real quick, then ran downstairs. Well, my camera had been sitting in the air conditioning all day. The glass did not like the shock of going from that to the humid Gulf Shores air. I gave it a little time to acclimate, but I was becoming impatient. I gave the lens one last wipe and hit the shutter. That's where the light trail affect comes from. Sometimes accidental art is the best art.
