Taking photographs at night just after the sun has gone down and the stars have started to come out, is a great time to learn and practice both Nightscape and Long-Exposure Photography
As you still have enough natural light to see what you are doing and set up your camera before it gets too dark, and you can practice taking photos above 30sec without the use of an ND filter

One thing I learned whilst trying out night photography, and that’s don’t forget your torch as the light just goes so quickly, I was lucky as the D7000 comes with a backlight option. Without this option I wouldn’t of had a clue what my camera was set to on the display lol!!!
I took the above image with my D7000 setup on a tripod and used my shutter release cable to fire the shot, once again setting my camera to manual and using bulb the shot was taken using my iPhone as a stopwatch.
Camera Settings:
Manual Mode, ISO 100, 121sec, F4 at 12mm
