Baby
A lighting nickname for a 1K tungsten Fresnel, and a separate name for the 5/8-inch mounting standard used on stands, plates and accessories. The context determines whether the crew is discussing a fixture or a mounting connection.
Baby Plate
A mounting plate fitted with a 5/8-inch baby pin, used to support compatible lighting or grip accessories where a stand is impractical. Sometimes called a 750 base plate in Canadian set terminology. The mounting method and permitted load depend on the equipment and surface.
Baby Stand
A baby stand uses the 5/8-inch baby mounting standard. Height, construction and rated load vary by model. A preemie stand is a low-height type, not another name for every baby stand.
Backdrop
Fabric, artwork or constructed scenery placed behind the subject to provide a background. It may represent a real location, create a plain studio setting or provide a coloured surface for compositing. Lighting and perspective help sell the intended effect.
Background
The area of the image behind the main subject. On set, “background” can also mean background performers, who populate a scene as pedestrians, customers or other supporting figures. The context separates a framing discussion from a direction to performers.
Back Light
Light arriving from behind the subject, often used to reveal an edge or separate the subject from the background. Its height, angle, intensity and softness determine whether the effect is a subtle rim, bright outline or broader backlit shape.

Barn doors
Adjustable metal leaves fitted to a compatible lighting fixture to limit spill and shape its beam. Their effectiveness depends on the fixture’s optics and apparent source size; they do not provide the same sharp control on every light.
Base Light
The general level of illumination established across a scene or working area. It provides a starting point for more selective lighting, but there is no universal minimum exposure or fixed ratio that every production must use.
Bayhem (Michael Bay Style)
A nickname for the kinetic spectacle associated with Michael Bay: rapid cutting, sweeping camera moves, dramatic low angles and elaborate action. It describes a recognisable approach to staging and editing rather than a formal genre or production method.
B-Cam
The camera designated B on a production. It may shoot an alternate angle, additional coverage or material assigned to a separate camera team. The letter identifies the camera and footage; it does not automatically rank the creative importance of every shot.
Beat
A small unit of dramatic action or a shift in a character’s thought, objective or emotion. In dialogue, “a beat” can also indicate a brief pause. Its meaning depends on whether the discussion concerns story structure, performance or timing.
Behind-the-Scenes (BTS)
Activity and material documenting how a production is made, including crew at work, rehearsals and interviews. BTS footage may be captured for publicity, education or bonus features, with access and filming coordinated around the main production.

Below the Line
Below the line is a production-budget classification covering many crew, equipment and post-production costs. It includes highly creative departments such as cinematography, production design and editing; it does not mean a crew member makes no creative decisions.
Bergmanesque (Ingmar Bergman Style)
A description of work recalling Ingmar Bergman, often through intimate psychological conflict, searching close-ups and questions of faith, identity or relationships. It is a critical comparison, and different films may evoke different aspects of his work.

Best Boy Electric
The gaffer’s principal assistant, responsible for much of the electric department’s crew, equipment and logistical organisation. The role supports the lighting plan by coordinating resources and workflow; the exact duties vary with the production and crew size.
Best Boy Grip
The key grip’s principal assistant, helping manage the grip crew, equipment, orders and day-to-day logistics. The role keeps the department organised while the key grip coordinates the production’s grip requirements with the cinematographer and other department heads.
Big Close-Up (BCU)
A tightly framed view of a face or other subject, used to emphasise expression or detail. Shot-size terminology varies between crews, so a big close-up is best confirmed with an actual frame rather than a fixed forehead-to-chin rule.
Bigelowesque (Kathryn Bigelow Style)
A description of filmmaking associated with Kathryn Bigelow, particularly physical immediacy, sustained tension and close attention to people under pressure. The comparison concerns style and dramatic approach rather than a fixed set of camera techniques.

Billing
The wording, order, size and placement of names in credits and publicity. Billing can reflect negotiated agreements as well as creative recognition. It is distinct from invoicing, although both uses of the word occur in production business.
Bit Part (Player)
A small acting role with limited dialogue, action or screen time. It contributes to the scene without carrying a major story arc. The term is descriptive; specific performer categories and contractual treatment depend on the production and applicable agreement.
Black List
Historically, the Hollywood blacklist excluded workers accused of communist associations. Separately, The Black List is the name of an industry organisation associated with unproduced screenplays. These meanings should not be confused with a general refusal to work with someone.
Blimp
A housing used to reduce unwanted sound. A camera blimp encloses a noisy camera; a microphone blimp surrounds a microphone to reduce wind noise. Despite the shared nickname, they solve different sound problems and are not interchangeable equipment.
Blocking
The planned positions, movement and interactions of performers within a scene. Blocking gives the camera, lighting, sound and other departments a shared understanding of the action. Rehearsing it before final setups helps prevent work based on conflicting assumptions.
Blocking Rehearsal
A run-through used to establish or refine the scene’s movement and positions. It lets the departments see the action and identify camera, lighting, sound or access requirements before committing to a setup or recording a take.

Blow Up
An enlargement from a smaller image format to a larger one, traditionally such as 16mm film to 35mm. Enlarging or upscaling changes the output format but cannot recreate detail that was never captured in the original image.
Blue Screen
A blue screen is a chroma key technique where subjects are filmed against a solid blue background so that the background can later be digitally removed and replaced with other images, environments, or effects in post-production. It functions similarly to a green screen, with the choice of color depending on wardrobe, lighting, and the specific needs of the production.
Board(s)
Shorthand whose meaning depends on the conversation: it may refer to a storyboard, a production scheduling board or the slate used to identify a take. Confirm the intended item when the department or context does not make it clear.
Book Light
A lighting arrangement in which light is bounced from a reflective surface and then passes through diffusion before reaching the subject. The effective source can be large and soft, while the extra bounce and diffusion reduce the available output.
Boom Mic (Microphone)
A microphone positioned on a boom pole or other boom support to capture sound close to the action while staying outside the frame. Shotgun and hypercardioid microphones are common choices; the location and recording needs determine the appropriate microphone.
Boom Operator or Boom Op
The sound-department crew member who positions and moves the boom microphone during takes. Working with the production sound mixer, the boom operator follows the performance while avoiding the frame, unwanted shadows and interference with the other departments.

Boom Pole
An extendable support used to place a microphone near a performer or sound source. The operator adjusts its position with the action while keeping it out of shot. Pole material, length and cable arrangement affect handling and reach.
Boom Shadow
A boom shadow is the unwanted shadow of a boom microphone or boom pole that appears in the camera frame during filming. It is considered a common mistake on set and can be highly distracting to audiences if not corrected. Boom shadows typically occur when lighting is positioned in such a way that the boom equipment casts a visible silhouette on actors, walls, or the set.
Bottle Episode
An episode built around a limited number of sets, locations or performers, often to contain production demands. It may rely on dialogue and character conflict, but the term does not guarantee that the episode is inexpensive to make.
Bounce Board
A reflective board used to redirect light toward a subject or area. White surfaces usually provide a broad, diffuse reflection; more reflective finishes behave differently. Larger bounce frames and fabrics serve a similar purpose but are not all boards.
Box Office
The term box office refers to the financial performance of a film in theaters, specifically the revenue earned from ticket sales during its release. It is one of the most common measures of a movie’s commercial success and is often reported daily, weekly, and in total (gross). The phrase originates from the literal “office” or booth at a theater where tickets were once sold.
Breakaway
A prop or set component designed to break in a planned way for an effect or stunt. Special construction reduces particular risks but does not make it harmless. Its use is coordinated by the appropriate effects, props and stunt personnel.

Breakdown Sheet
A record of the production elements required for a scene, such as cast, props, vehicles, locations and effects. Breakdown sheets help departments identify requirements and support budgeting, scheduling and preparation before filming.
Bridge Shot
A bridge shot is a type of transition shot used in film and television to connect two scenes separated by a jump in time, place, or narrative flow. It helps maintain continuity by providing a visual “bridge” for the audience, smoothing over what would otherwise feel like an abrupt cut.
Broadcast News
News produced for television or other broadcast distribution, combining reporting, recorded packages, live contributions and studio presentation. Production roles often overlap with documentary and factual filmmaking, while deadlines, verification and delivery requirements shape the workflow.
B-Roll
Supplemental footage edited alongside the main action or interview. It can show a location, illustrate a detail, establish context or cover an edit. Useful B-roll gives the editor specific visual information rather than simply filling time.
Budget
In filmmaking, a budget is the complete financial breakdown of all costs associated with a production. It accounts for everything from development and pre-production through shooting, post-production, marketing, and distribution. A budget may start with a fixed amount of money already raised, which is then allocated to departments, or it may be built from the ground up as a projection of costs to guide fundraising efforts.
Bug Light
A nickname associated with compact lighting units, including Joker-Bug HMI equipment. It is not a dependable specification for a generic open-face lamp. Confirm the fixture model, wattage and optical configuration when the term appears on a gear request.
Butt Dolly
A low rolling platform or seat that lets a camera operator move while working near floor level, often with a handheld camera. Designs vary, so the name alone does not establish track compatibility, mounting options or load capacity.
