A useful technique in night photography is the long exposure. The effects that can be captured with a long exposure are stunning and have an ethereal quality. The most important tool that you will need is a sturdy tripod, and a DSLR camera that allows for long exposures.

2.Making Stars Trails:
A long exposure on a starry night can produce
beautiful light trails created by the stars and the rotation of the earth. The
best way to frame the image is to include an element of interest such as an old
tree in the foreground. Place your camera on a tripod and focus the lens to
infinity. You’ll want to use a cable release to eliminate camera shake of any
kind, as it will RUIN your photo. Set the camera to B "Bulb" shooting
mode and set your aperture between f/2.8 - f/4 for optimal results. Depress the
remote to open the shutter. You should keep your ISO at 100 to keep the digital
noise at a minimum. To complete the photo after your desired elapsed time,
depress the remote again, and release the shutter. These exposures can be 15
minutes to several hours long..
3.Stunning Light Trails:
Traffic
head light and tail light trails give a stunning effect and are a great way to
get acquainted with long exposure times. Select a busy road that has lots of
traffic at night. Use a sturdy tripod and position the camera so that it has an
overview of the area. Use a small aperture of f/16 or smaller for a greater
depth of field, making most of the image in focus. The longer the exposure, the
more lines will appear and the longer they will look.
4.Determining Exposure:
The exposure of your night time image
will vary depending on certain factors. If there is a lot of ambient light then
the shutter speed will be shorter. If you are shooting somewhere very dark,
then the shutter speed will need to be longer. To capture the effects of light
trails you need a shutter speed of at least 1/15th of a second, which means you
must use a tripod. The image of the Houses of Parliament required a 6 second
shutter speed, which is slow enough to capture the traffic trails. The f/8
aperture allowed the building to be sharp. The more you practice the more you
will become tuned to the exposure you need for the effect you want.
