FZ200 - Night Shot Test - Different ISO etc.

With regard to my other thread...
Low Light - Christmas Lights/Celebrations Camera?
I took some test night shots with my FZ200 trying to simulate a Christmas lights display. I thought I would share the results with you. I'd also be interested in your analysis because I don't have a trained eye yet.

These are all directly out of camera. They were taken using a tripod at -1/3 exposure.

Intelligent Auto Mode with Hand Held Night Shot turned on

Scene Mode - Night Scenery - I don't know why the framing changed

Scene Mode - Night Scenery - Framing adjusted to be like the IA Night Shot

ISO 100
