For these images I worked with pen lights and very long exposures (2 - 3.5 mins). I set my camera on BULB, shot at ISO 100 and f/11. I was part of a team of 4 (photo class at the local university). Then we used a pen light to make lines or outline the subjects. This was a fun exercise. You need a tripod, a dark area (inside your home or outside) and a cable release - or remote control. We shot off a flash prior to taking each picture for additional light. The flash was hand held off camera. Click on each thumbnail to view a larger image.
