I have Canon Rebel XS (EF-S 18-55mm f/3.5-5.6 IS Autofocus Lens). I have been trying to take decent night photographs for a while. But it seems to take a lot of effort. Can we take good night shots without a tripod? Also a slight motion in subject is leading to blur due to high exposure times. But if I reduce the exposure time, I cannot properly capture the landscape behind. Can you provide some guidance for taking great night shots?
EDIT: I am looking for scenario where downtown is in the background and person is in front. I am not much interested in taking pictures of moon and stars. I would be also interested to know how we take good shots of landscapes just with moonlight.
EDIT: I am including the picture I took with Chicago downtown in the background and my friend in the foreground. It came out decent, but it took a lot of effort and even then it was blurry. Hope this gives you a good idea of the kind of picture I am trying to take.
EDIT: Thanks guys for all your detailed responses. Obviously there is no one right answer but for just what it's worth I am picking one of them.
