How to Set Up a Light

1. What are three key important details when setting up a light properly?
2. What are the proper terms when instructing someone to change where the light is pointing?

When setting up a C-stand, the legs at the bottom either have to slanting  downwards towards the middle or in a perpendicular fashion. Leaving the legs too high up can result in an unstable C-stand. When tightening the knob, it should only be tight enough to be able to be loosened by the hand or finger. One sandbag is required for all lights, and more if the light is heavy.  All cables must be secured under a rubber mat or taped down so that the people do not trip over them. When turning on the light, it is important to call out "striking" so that people are not looking directly into the light. When turning off the light, call out "saving" so that people do not mistake it for lighting outtage. There are three main terms used for the movement of the lighting source: tilt, pan, and stick (up/down)
