Hi Matt,
Thanks for those comments.
I took a few shots and purposely kept the ones with the people wandering about - like ghost images.
I managed a couple of light trails (Passing traffic) but that lit the shot up too much. I liked the moody shot.
Like you said I wound the ISO up (400 IIRC) to get the grainy feel as well as the extra light.
I will try Tripod shot and wind the ISO down to 100 and see how that looks tho.
Specifically I was after a Xmas street scene but not Xmassy.
