Night Photography NIKON digital cam.
Wait until the sun goes down.
In many ways night photography is just like day photography, except there's less light. With less light, you need a slower shutter speed, a wider aperture, a faster ISO, or a combination of all three. Or else you need to add light.
Just like day photography, the best camera settings (and other things) depend on what you want the photograph to say to the viewer.
You can add light by using the flash, car headlights, etc. The flash doesn't have much range; if you're sitting in the stands at a night sporting event your flash isn't going to affect any pictures you take of the action on the field. Another effect of the short range is that if you take a flash picture of a person at night, you're likely to have an almost completely black background. If you want something of the background to show, use the Night Portrait mode (and a tripod).
If you want to take a picture of a night landscape (or the night sky, with star trails) then turn off the flash. Put the camera on a tripod or other steady support and use a slow shutter speed.
If you're taking a picture of the full moon, then it's not night photography at all. The full moon is just a big rock under a midday sun, so treat it as such.
