thanks again everyone.
I need to give Dina credit for #3 , she told me where to point the camera on that one!
Thanks Will, I like #2 a lot too, I want to take it again to highlight the gondola brighter. I guess I need to either take it earlier or use a flash with a slow synch? Using the shadow/highlight tool in ACDsee on this shot just inroduces a ton of noise.
msummers, I agree on the sky on #4. My camera (maybe every camera) has a few minutes just after dark where it makes the sky this beautiful blue that really isn't there.
