Where most people use flashlight for a city evening picture, one can make better pictures whithout. It is all in the perception what is ment by night photography. Mainly evening photographers takes pictures of their friends in a bright city. Even historical buildings are flashed on camera.
When using the whole capacity of the camera the results can be stunning. By using the maximum aperture setting in combination with a very low iso setting the exposure time increase. Here is the point. By using a long exposure the camera will collect sufficient light for a good picture. Don’t border of people passing by, they will not be captured unless they stand still. Of course you need a tripod to avoid camera movements. Try the street or a fontainwall or something else where the camera can be placed on.
Another advantage when photographing during the night are the stars on lightpoints. They are the result of the diafragma from the camera. The lightpoints can produce beautifull reflections on water surface. The lower the point of view, the longer reflections you’ll get.
