Filmmaking Dictionary: Number 1 / 1x Net / Single Scrim
Definition
A single net or single scrim reduces light intensity using an open mesh. On equipment lists, 1x may indicate a single-strength item, but it can also mean a quantity of one. Confirm the intended meaning.
Film crews commonly distinguish a fabric net mounted in a frame from a wire scrim fitted to a compatible lamphead. Both reduce light, but they are different pieces of equipment with different handling requirements.
Net Versus Wire Scrim
- Fabric net: Positioned in the light’s path, often on a separate frame or support.
- Wire scrim: Installed in the designated accessory holder of a compatible fixture.
- Single: A lighter reduction than the corresponding double in the same product family.
- Double: A stronger reduction, not a universal promise of one exact transmission value.
A single is often associated with roughly half a stop of reduction, but the actual material and fixture matter. Use the product’s stated performance and check the result rather than assuming every single net and wire scrim behaves identically.

Why It Is Not Simply Diffusion
A net or wire scrim is primarily used to reduce intensity while preserving much of the source’s existing character. Diffusion deliberately redistributes the light and can make an illuminated surface act as a larger source.
A net can still affect the image in practical ways. Colour, bounce, placement and visible mesh shadows matter. Position and inspect it with the actual source and subject rather than relying only on the material’s name.
Example on Set
A tungsten Fresnel gives the desired direction and shadow quality but is slightly too bright. A suitable wire scrim can reduce its output without moving the light or dimming the lamp. A separate net may be used where the crew needs to control light reaching a particular area of the scene.
These choices solve different setup problems. The gaffer and key grip coordinate the reduction, placement and support according to the intended lighting result.
Practical Checks
- Confirm the fixture or frame compatibility.
- Inspect the mesh and supporting hardware.
- Check the actual exposure reduction and any visible pattern.
- Follow heat-clearance and handling requirements, especially around hot lampheads.
- Secure the support arrangement for the actual position and conditions.

Frequently Asked Questions
Does ‘single’ mean one stop?
No. It identifies a material or construction class. Verify the actual stop loss.
Can a single net replace a softbox?
No. Reducing intensity and creating a larger diffused source are different lighting tasks.
