Sorry - more harbourside shots. Gotta love Sydney at night. I'll add them as I go. Just trying to get used to the sensitivity of the D40 at night - a pretty steep learning curve!
I took a bunch of shots of each subject, and like Andrew (Rocketboy) will try a little HDR processing in PS. These were taken at 200 ISO with a 18-55 AF-S ED lens set to around 50mm. I took shots of each subject for 30, 25, 20, 15, 13, 10, 8, 6, 5, 4, 3, 2.5 & 2 seconds at f/6.3. This is a pretty bright lens and the CCD is very light sensitive, so I'll go out again tonight and try again by stopping down to f/7.1 or f/8.
Cheers - and thanks for looking

Chris
