So, here is the deal! Put your camera on Manual, yes, I said manual! That's when you will catch some of the most amazing pictures! You want to leave your shutter open as long as you can to create movement. You will need a remote or put it on timer once it is focused on what you want to get in the picture. The shutter should be under 30, I would just keep dialing down until you get the movement and light you want in your picture. The aperture should be above an 11, I say this because you want to get as much detail in the background as you can. Once it's all set you can set your timer or press your remote and see what you get. If it's pitch black outside you may want to switch to "Bulb" that one is fun because it stays open as long as you keep the trigger down, I use a remote for this one. : ) Here are some of my "BULB" exposures they were longer then 5 minutes.
