    A heat-tolerant sheet used to alter a luminaire’s color or intensity.

  • Lighting louver

    A directional cell or vane assembly that reduces high-angle spill from a broad light source.

  • Loop former

    A camera mechanism or guide that establishes the required slack loops around an intermittent film movement.

  • Los Angeles position

    The commonly used name for placing a full apple flat in its lowest and broadest orientation, roughly 8 inches high.

  • Low-boy stand

    A short heavy-duty stand that positions junior-mounted fixtures or equipment near floor level.

  • LPL mount

    A large-diameter ARRI lens mount designed for modern large-format cinema lenses and metadata contacts.

  • Macro lens

    A lens designed to focus closely and reproduce small subjects at relatively high magnification.

  • Mafer clamp

    A compact padded jaw clamp with a receiver used to mount lightweight production accessories.

  • Matte box

    A camera-front accessory that shades the lens and holds filters in a controlled position.

  • Menace arm

    A cantilevered rig that projects a fixture or modifier horizontally from a supported stand or structure.

  • Microphone diaphragm

    A thin membrane in a microphone element that moves in response to changes in sound pressure.

  • Microphone maximum SPL

    The highest specified sound-pressure level a microphone can accept before exceeding a stated distortion limit.

  • Microphone self-noise

    The equivalent acoustic noise level produced by a microphone and its internal electronics when no intended sound is present.

  • Microphone shock mount

    An elastic or engineered suspension that reduces vibration transmitted from a boom, stand, or camera.

  • Microphone transducer

    The microphone element that converts acoustic energy into a corresponding electrical signal.

  • Minus green gel

    Magenta color-correction media used to reduce a green cast in a light source.

  • Mirror board

    A reflective board used when a production needs a more specular bounce than foam or fabric provides.

  • Monitor hood

    A shade surrounding a display to reduce ambient light and reflections during viewing.

  • Monopod

    A single-legged camera support that reduces carried weight while retaining mobility.

  • Multitrack field recorder

    A portable recorder that captures multiple isolated and mixed production-audio channels with metadata and timecode.

  • Muslin

    A woven fabric used as diffusion, bounce, backdrop, or scenic material depending on its finish.

  • NATO rail

    A compact dovetail-style accessory rail used for sliding and locking compatible camera attachments.

  • Negative fill

    An opaque surface placed near a subject to reduce ambient bounce and deepen contrast.

  • Neutral-density filter

    An optical filter intended to reduce exposure without materially changing color.

  • Neutral-density gel

    Lighting media intended to reduce output without substantially shifting color.

  • New York position

    The commonly used name for placing a full apple in its tallest orientation, roughly 20 inches high; regional terminology can vary.

  • Omnidirectional microphone

    A microphone designed to respond approximately equally to sound from all directions.

  • On-set monitor

    A calibrated or production display used to evaluate framing, focus, exposure, and image continuity.

  • Onboard monitor

    A compact display mounted on the camera for operating, focus, exposure, or configuration feedback.

  • Open-face fixture

    A reflector-based light without a lens, producing a broad, hard output that can be modified with diffusion.

  • Optical low-pass filter

    A sensor-front optical element used to reduce aliasing and moiré before image sampling.

  • Overhead frame

    A suspended or supported frame that holds diffusion, bounce, or negative fill above a scene.

  • PAR can

    A compact parabolic-aluminized-reflector fixture that produces a directional beam for stage or location lighting.

  • Pipe clamp

    A clamp shaped to attach a fixture or accessory to pipe of a specified diameter.

  • Pipe grid

    An overhead network of structural pipe used as approved mounting positions for studio equipment.

  • PL mount

    ARRI’s positive-locking cinema lens mount, widely used with professional motion-picture lenses.

  • Plant microphone

    A microphone hidden or placed within scenery, props, vehicles, or the set to cover a defined action area.

  • Plus green gel

    Color-correction media that adds green to better match selected discharge or fluorescent sources.

  • Polarizing filter

    A rotatable optical filter used to manage polarized reflections, glare, and sky saturation.
