Light Leaks and What to Do About Them

I prefer contrasty soft light for most of my work, and while I’m not averse to hard light accents there’s one thing I absolutely detest: unintended hard light flooding randomly across the set. Here are the three most common causes I’ve experienced, and how I fix them…

Black wrap exists for a reason: it is the single best tool to eliminate light leaks through barn doors.

Allow me to explain:

There’s a gap between a lamp and its attached barn doors to allow the use of wire scrims for intensity control. This is fine if the light is hung in a grid or rigged some distance from the set, but if it’s on the set–in the form of an active bounce, for example–it’s very easy for light to pass from the lamp’s lens through that crack in the barn doors and rake across the set. It can be a very subtle effect, and in many situations it’s nearly impossible to see… until the camera is rolling and the actor is giving the performance of their lifetime. That’s when you notice that there’s an extra shadow cast whenever they move their hands in front of their face. Ack!

Solution: I ask my crews to stay on top of this and black wrap the side of any lamp where that barn door gap faces the set.
