*Try using minimal flash or best no flash at all when you're shooting in a hazy enviroment. You'll just end up with millions of grey dots aka "ÖRBS" in your photo.
* Needless to say, a tripod is a man's best friend when it comes to night shoots. However that night, I didn't bring my tripod down from the car. LAZY. So use what ever support you have to prevent blurry shots.
