Using Flags On Set

I learned that a flag is a device in the lighting industry used to block or control light by casting shadows, essentially acting as a tool to selectively block light from reaching certain areas of a scene, most commonly used in photography and filmmaking to precisely shape the light on a subject by creating negative fill or cutting off unwanted light spills. Another important thing I learned was bouncing your light. Bouncing light is more pleasing and forgiving to the actors face it's softer quality. You achieve this by enlarging the the light and what area its coming from it will wrap around the subject. On some bigger set some gaffers tend to throw up a huge source and let the grips almost always that first step is to bounce it.
