How Three Lights Build a Face
Three-point lighting builds a face out of one bright source and two corrections. The key light sets the exposure and the direction; the fill softens the shadow the key creates without erasing it; the back light separates hair and shoulders from whatever is behind them. Remove any one and the picture flattens.
The order matters more than the equipment. Teams with expensive lights still produce flat footage because all three are switched on at once and adjusted together, which makes it impossible to tell what each one is doing. What stays out of the published version is gear specifics: named fixtures, wattages, and modifier brands date quickly and vary with whatever the team already owns.
Six scenes carry the setup: one on placing the key and why forty-five degrees is the default, one on judging exposure from the key alone, one on adding fill and how far to lift the shadow, one on the back light and the separation it creates, one on the three mistakes that flatten a shot, and one on the check to run before recording.
