Scrim

What this is about

A scrim solves the everyday problem of a lamp that is right in every way except brightness. Dimming a tungsten unit would drag it warmer and break the match with the other lamps; moving it back would change the shadow angle the DP just approved. The standard set is colour-coded — green for a single, roughly half a stop, red for a double, roughly a full stop — and half scrims cut only one part of the beam, which is how a gaffer evens out a hot spot on a wall.

A term only helps when everyone on set means the same thing by it — so what follows is how it is used, not a dictionary definition.

What runs differently here

Where this differs from the general case:

• Single and double scrims cut roughly half a stop and a full stop; stacking them adds up, at the cost of some texture.
• Unlike dimming, a scrim leaves the color temperature of a tungsten unit exactly where it was.
• Half and graduated scrims darken only part of the beam, which evens out a hot spot without moving the lamp.

With TillyGen

Scrim sets belong to the lamp line in TillyGen's equipment list, so a rental order does not arrive with fixtures and no way to trim them.

Change one constraint and the consequences travel through the whole plan: affected shots are flagged, the call sheet is regenerated, and nobody keeps working from yesterday's version.
