Hi guys and gals,
I am going for a holiday soon and the place I'm going to is overlooking a large marina with lots of boats.
I want to take some night shots, lights reflecting on water, sunsets, sunrises, that sort of thing. I have seen some photos on here of lit up streetscapes and wanted to know if maybe someone could help me with some manual settings for night shots like that.
I am still learning about my camera and the auto setting just doesn't come out very good at night.
My camera is a Fuji S5700. Info Here
Any help and suugestions appreciated.

You have a night picture setting on the camera, page 54 in the manual, try it out around home before you go on vacation to see if you like it. Don't forget to use a tripod. If you don't like the night setting you will have to put it in manual and play with it. Maybe adjust your white balance. My white balance was spread over the entire picture area, I changed it so it's more in the center. I prefer that look to my sunrise shots. But play around with it as much as you can, the great thing about digital is you don't waste any film..

This is some of the night shots I took while on holidays. I think I have it figured out now.
The night setting (as suggested by Wildabeast) and a tripod was used.

I can't see the photos (they're blocked at work), but if there's a color cast it's caused by the higher ISO for the Night setting. You can try setting it to manual and using a wide open (low number value) F-stop, along with a slow shutter speed and middle to high ISO number. Tripod is a must. It's digital, so take loads of photos-it won't cost a nikel to look at them (as compaired to paying to have film developed).
