  • Combo stand

    A heavy-duty stand with interchangeable junior and baby receivers for lighting and grip equipment.

  • Condenser microphone

    A microphone whose diaphragm and charged backplate form a sound-sensitive capacitor that converts acoustic vibration into an electrical signal.

  • Condenser microphone backplate

    The rigid conductive plate positioned close to a condenser microphone diaphragm to form a variable capacitor.

  • Condor

    Film-set slang for a telescopic or articulating boom lift used to elevate lighting, diffusion, rigging access, or personnel.

  • Contact microphone

    A transducer that captures vibration through direct contact with an object or surface.

  • Contrast viewing glass

    A dark monocular viewing filter used to evaluate relative lighting contrast and source direction without continuously viewing the full scene brightness.

  • Core load

    Motion-picture film wound on a hub without the protective flanges of a daylight spool.

  • Crab dolly

    A steerable camera dolly capable of moving laterally or diagonally as well as forward and backward without relying solely on straight track.

  • Crank stand

    A stand using a geared handle or winch to elevate heavy lighting, frame, or speaker loads.

  • CTB gel

    Color-temperature-blue correction media used to cool the visible output of a light source.

  • CTO gel

    Color-temperature-orange correction media used to warm the visible output of a light source.

  • Cucoloris

    An irregular patterned screen placed in a light path to cast broken shadows and create texture on a subject or background.

  • Cutter

    A large flag used to remove a controlled portion of light from a set or lens.

  • Cyclorama

    A large seamless curved background that removes the visible floor-to-wall corner and creates an apparently continuous field.

  • Daylight load

    Film supplied on a spool designed for loading in subdued light under the stock maker’s instructions.

  • Daylight spool

    A flanged film spool designed to limit edge exposure during subdued-light loading and unloading of compatible formats.

  • Diffusion

    A translucent material that scatters light, reducing contrast and softening the apparent source.

  • Dimmer

    A controller that varies fixture power or output within the fixture and electrical system’s rated limits.

  • Diopter

    A close-focus optical attachment that reduces the minimum focusing distance of a lens.

  • Directional RF antenna

    An antenna designed to favor radio-frequency reception or transmission in selected directions.

  • Director’s monitor

    A production display provided for creative review of framing, performance, continuity, and takes.

  • Distro box

    A portable power-distribution unit that divides a feeder into protected branch circuits.

  • Dovetail plate

    A tapered sliding plate that lets a camera assembly mount, balance, and release from compatible support.

  • Duckbill clamp

    A wide, flat-jawed clamp used to hold foam board, beadboard, or similar sheet material.

  • Dutch head

    A camera support head providing controlled roll-axis movement for canted framing.

  • Duvetyne

    A light-absorbing fabric used for flags, masking, and negative fill.

  • Dynamic microphone

    A microphone using electromagnetic induction, commonly valued for robustness and high-level handling.

  • Edge number

    Human- or machine-readable identification printed along film edges to locate stock and footage.

  • EF lens mount

    Canon’s electronic bayonet lens interface, used on still and some cinema camera systems.

  • Eggcrate grid

    A fabric or rigid cellular modifier that limits the spread of a soft source.

  • Eighth apple

    A thin apple-box riser, commonly about 1 inch high, used to make a small controlled height correction.

  • Electret condenser microphone

    A condenser microphone whose capsule uses permanently charged electret material rather than requiring external polarization voltage.

  • Electrical tape

    A flexible insulating tape intended for electrical conductors and connections; it is not a substitute for gaffer tape.

  • Electronic viewfinder

    A camera-mounted electronic display used by the operator for framing, focus, exposure, and status.

  • Elephant blocks

    A three-legged modular riser system designed to provide stable incremental height changes in a smaller package than traditional apples.

  • Ellipsoidal reflector spotlight

    A hard-beam fixture with shutters and an accessory plane for precise theatrical control.

  • Extension tube

    A non-optical spacer that increases lens-to-sensor distance for closer focusing.

  • False color

    A monitoring overlay that assigns colors to measured exposure ranges for rapid image evaluation.
