New amiture photographer needs help.

You've got lots of great "photographically correct" answers here. I'm going to get a little pragmatic, and build on what the "famous Wilba" said.

Rather than jump with both feet into full-on manual control, I'm going to give you a good "baby step". Move your top dial one position from the "Green Box" to the "P" position. The main difference here is that on the green box the camera pretty much controls everything. On "P", you get to second-guess it, and take some of that control back, without having to set everything yourself.

Once you are on "P", if it is dark, you will need to press the button on your camera labeled "ISO", then spin the dial to increase the number, probably to at least 1600, or maybe even 3200. What this does is make the camera's sensor more sensitive to incoming light, and therefore able to shoot with a faster shutter speed. This helps get rid of the fuzziness that comes from all kinds of movement, whether it is the subject, or the camera. The down side of this is that it introduces "noise", which essentially means "static" or little dots all over your picture. The higher the ISO, the more noise is introduced.

Once that is done, you can take pictures under pretty dark conditions. However, the camera will probably still have trouble focusing. As noted above, it uses the flash to help it do so. In this case, you probably need to do it yourself. You probably also don't want the flash used (it will messs up the atmosphere you are trying to get), so push it down. (In P mode, you decide whether to use it or not.) There are two little switches on your lens. Set one to MF, and the other to IS ON. This allows you to set the focus with the thin ring at the end of the lens. The fat ring is the zoom, which controls how much of the scene you take in. You probably want that ring set to 18 (the "widest" setting).

Now you should be ready to get as good a picture as possible of this scene.

Don't forget to turn the switch to AF, and drop the ISO back down to 100 when you are done with the dark!

Enjoy!
