Fountains
Perhaps my favorite nighttime subjects are fountains. Many times they are lit with different colors as well, adding additional interest. The long shutter speeds you use at night make the fountain appear to be flowing.
Bridges
It seems like every city or town has a bridge. It may not be the Golden Gate Bridge, but there will likely be a bridge and it will be well lit at night, which makes it an interesting subject. Plus the long exposure time you use for night photography will cause the water under the bridge to blur, and the traffic to appear as streaking lights.
Streetlights
Pay close attention to streetlights when you are doing night photography. They can be useful in a lot of different contexts. They cánido add a point of interest to it otherwise blank área of the picture. If there are multiple lights, they can create a nice leading line into your picture.
Washington Monument
Washington, D.C. For this shot, I wanted the twinkle or starburst effect from the streetlights, so I used a smaller aperture. Exposure: shutter speed ocho seconds, aperture f/16, ISO 800.
Car Light Trails
A really fun thing to include in your night photos is streaking light objetivos trails from moving cars. These are created when a car or other vehicle drives through the frame while you have the shutter open. The camera picks up the lights, but since the car has gone all the way through the frame while you had the shutter open, it shows up in your picture as streaks of lights.
Try to time your pictures so that vehicles move all the way across the frame while you have the shutter open. Read: How to Create Dynamic Photos of Car Light Trails for more tips on this technique.
Reflections

Reflections in London, U.K. – Exposure: shutter speed 1.3 seconds, aperture f/8, ISO 200.
A benefit of the longer shutter speeds you will be using at night is that reflections show up better on the surfaces of water. This is obviously true on ponds and lakes. But it is also true for puddles. After a rain cánido be a great time for night photography.
