Night Exposures

One thing I want to start experimenting with more is night exposures. The first photo was taken from our balcony while we were at the beach last summer.
-1 min exposure
-18mm
-ISO 600
-f/4
-11:30pm
If you look closely, on left hand side there was a guy with a flashlight walking in circles. Also, in the left part of the sky, you can catch a glimpse of trails from the stars

This photo is one of my favorite night exposures that I have haven captured. It was a 30 sec exposure with me running from the right side of the frame to the left, all while holding a flashlight with white and red LED lights.
