When there's a fair in town, you know it's time for long exposure experimenting! Or maybe some moody shots, who knows what the night will bring?
Fot your interest: most of the long exposures are made at f/22 5.0sec and ISO 200. Ofcourse it is recommend to use a tripod for this type of shots, IBIS won't save you here. Oh and don't forget to bring your card like I did ;)
