Cinematography: the basics

• A. The length of time light hits the sensor
• B. The amount of light that passes through the lens ✓
• C. The sensitivity of the sensor to light
• D. The focal length of the lens

Why: Aperture is the adjustable opening in the lens diaphragm. A wider opening lets more light through, while a narrower one lets less. Shutter speed controls time, ISO controls sensor sensitivity, and focal length relates to field of view.

• A. 1/50 second ✓
• B. 1/120 second
• C. 1/24 second
• D. 1/1000 second

Why: The 180-degree shutter rule suggests a shutter speed of about double the frame rate, so 1/50 second for 24 fps. This produces natural motion blur that looks cinematic. Much faster speeds can make motion look choppy.

• A. The lens's maximum aperture
• B. The sensor's sensitivity to light ✓
• C. The number of frames captured per second
• D. The distance between the lens and subject

Why: ISO indicates how sensitive the camera's sensor is to light. Higher ISO values brighten the image but typically add more digital noise, while lower values produce cleaner images that require more light.

• A. It is cut in half
• B. It doubles ✓
• C. It stays the same
• D. It quadruples

Why: Each full stop change in aperture either doubles or halves the amount of light. Moving from f/4 to f/2.8 is one stop wider, which doubles the light reaching the sensor.

• A. Greater depth of field with everything in focus
• B. Shallower depth of field with a blurred background ✓
• C. Reduced exposure with darker images
• D. Slower shutter speeds are automatically required

Why: A wide aperture produces a shallow depth of field, meaning only a narrow plane is in sharp focus while the foreground and background blur. This is a popular tool for isolating subjects in cinematography.

• A. The maximum aperture of the lens
• B. The angle of view and magnification of the subject ✓
• C. The color temperature of the captured image
• D. The shutter speed required for proper exposure

Why: Focal length determines how wide or narrow the field of view is and how large the subject appears in the frame. Shorter focal lengths capture a wider angle, while longer focal lengths magnify distant subjects.

• A. A 200mm telephoto lens
• B. A 85mm portrait lens
• C. A 24mm lens ✓
• D. A 400mm super-telephoto lens

Why: A 24mm lens has a short focal length, which produces a wide field of view that captures more of the scene. Focal lengths below roughly 35mm are typically considered wide-angle on full-frame cameras.

• A. It makes the background appear larger and more distant
• B. It makes objects in the background appear closer to the subject ✓
• C. It has no effect on how the background looks
• D. It blurs the background only when the lens is wide open

Why: Telephoto lenses compress perspective, making elements at different distances look closer together in the frame. This is why long lenses are often used to stack background details behind a subject.

• A. It produces extreme distortion that suits dramatic moments
• B. It offers a natural perspective close to human vision, which suits character-focused storytelling ✓
• C. It only works in low light conditions
• D. It eliminates the need for focus adjustments

Why: A 35mm lens is often described as close to the natural perspective of the human eye, making it a versatile and unobtrusive choice for dialogue and character work.

• A. The field of view becomes wider
• B. The field of view stays the same but the image gets sharper
• C. The field of view becomes narrower ✓
• D. The field of view changes only in color rendering

Why: Doubling the focal length roughly halves the angle of view, so the 100mm lens captures a narrower slice of the scene and magnifies the subject more than the 50mm lens.

• A. Dividing the frame into three equal horizontal bands only
• B. Dividing the frame into a 3x3 grid and placing key subjects along the lines or intersections ✓
• C. Filming every scene with exactly three actors in frame
• D. Using three lights for every shot regardless of the setting

Why: The rule of thirds divides the frame into nine equal sections using two horizontal and two vertical lines. Placing subjects on these lines or at their intersections creates a more balanced and visually engaging composition than centering everything.

• A. The height of the ceiling in a filming location
• B. The space between the top of a subject's head and the top edge of the frame ✓
• C. The distance between the camera and the subject
• D. The amount of light falling on a character's face

Why: Headroom is the empty space above a subject's head within the frame. Too much headroom can make a subject look lost or small, while too little can feel cramped. Good headroom is usually kept consistent across a scene.

• A. Extreme close-up
• B. Medium shot ✓
• C. Medium close-up
• D. Long shot

Why: A medium shot typically frames a subject from about the waist or knees up, balancing the character with some of their surroundings. It is one of the most common shots for dialogue scenes because it shows both expression and body language.

• A. The empty space on the floor where actors walk
• B. Extra space in the frame in the direction a subject is looking or moving ✓
• C. The area in front of the lens that must remain clear of objects
• D. The corridor leading to the set from the parking area

Why: Leading room gives a moving or looking subject space to move into, which feels natural to the viewer. Without it, the subject can appear to be pressing against the edge of the frame, creating unwanted tension.

• A. To reveal fine facial details and emotion
• B. To show the full environment and orient the viewer to where the action takes place ✓
• C. To hide the setting from the audience
• D. To show only the lighting equipment on set

Why: Wide or establishing shots show the broader setting, helping the audience understand the geography and context of a scene. They are typically used at the start of a scene or sequence to orient viewers before moving to closer shots.

• A. Tilt
• B. Pan ✓
• C. Dolly
• D. Truck

Why: A pan is a horizontal rotation of the camera on a fixed axis, like turning your head left or right. A tilt is the vertical equivalent, while dolly and truck involve physically moving the camera through space.

• A. A dolly moves toward or away from the subject, while a truck moves sideways alongside it ✓
• B. A dolly moves sideways, while a truck moves toward or away from the subject
• C. A dolly is done handheld, while a truck requires a tripod
• D. There is no difference; the terms are interchangeable

Why: A dolly shot moves the camera forward or backward along the subject's line of sight, while a truck shot moves the camera laterally, side to side, often parallel to the action. Both use wheeled platforms on tracks or smooth floors.

• A. Steadicam ✓
• B. Slider
• C. Jib
• D. Monopod

Why: A Steadicam is a stabilizing rig that uses a gimbal, springs, and counterweights to isolate the camera from the operator's body movements, producing smooth shots while walking. Sliders and jibs are different tools for linear and crane-style movement.

• A. To lock the camera permanently in one position
• B. To allow smooth, controlled pans and tilts through hydraulic damping ✓
• C. To adjust the lens focal length remotely
• D. To attach lighting equipment to the tripod

Why: A fluid head uses viscous fluid inside its mechanism to resist motion, giving smooth, even-speed pans and tilts without jerky starts and stops. This is essential for professional-looking camera movement on a tripod.

• A. It limits how far a camera can pan in one shot
• B. It keeps the camera on one side of an imaginary line between two subjects to preserve screen direction ✓
• C. It requires the camera to rotate 180 degrees between every shot
• D. It sets the maximum speed for a dolly movement

Why: The 180-degree rule keeps the camera on one side of the action line so that subjects maintain consistent screen direction and the audience isn't disoriented. Crossing the line during movement can confuse spatial relationships.

• A. To fill in shadows created by the main light
• B. To provide the main illumination and define the subject's form ✓
• C. To separate the subject from the background
• D. To light the background evenly

Why: The key light is the strongest source in a scene and provides the main illumination, shaping the subject and establishing the mood. Fill, back, and background lights support it.

• A. How hot the light fixture gets during operation
• B. The warmth or coolness of light, measured in Kelvin ✓
• C. The intensity of light falling on a surface
• D. The amount of heat radiated onto the subject

Why: Color temperature describes the color appearance of light on the Kelvin scale. Lower values (around 3200K) appear warm and orange, while higher values (around 5600K) appear cool and blue, similar to daylight.

• A. Light intensity doubles when the distance from the source doubles
• B. Light intensity decreases proportionally to the square of the distance from the source ✓
• C. Light intensity is unaffected by distance in open spaces
• D. Light intensity increases with the square of the lamp's wattage

Why: The inverse square law states that light intensity falls off with the square of the distance. Doubling the distance from a light reduces its intensity to one quarter, which is why moving a light closer to a subject has a dramatic effect on exposure.

• A. Hard light is always warmer in color than soft light
• B. Hard light produces sharp, defined shadows, while soft light produces gradual, diffuse shadows ✓
• C. Hard light requires more power to produce than soft light
• D. Soft light can only be produced by natural sunlight

Why: Hard light comes from small or distant sources and creates crisp, well-defined shadows with high contrast. Soft light comes from large or close sources, such as a softbox, and wraps around the subject with gentle, gradual transitions.

• A. To increase the light's color temperature
• B. To spread and soften the light, reducing harsh shadows ✓
• C. To concentrate the beam into a narrower spot
• D. To block light from reaching the subject

Why: Diffusion materials such as silk, scrim, or diffusion gel scatter the light rays before they reach the subject. This widens the effective source size, softening shadows and producing a more flattering, even illumination.

• A. Lumens
• B. Kelvin ✓
• C. Candela
• D. Lux

Why: Color temperature is measured in Kelvin (K). It describes the color appearance of a light source, with lower values appearing warmer (more orange) and higher values appearing cooler (more blue).

• A. 3200K
• B. 2700K
• C. 5600K ✓
• D. 1800K

Why: Clear daylight is roughly 5600K, which is why 5600K is the standard color temperature for daylight-balanced film stock and LED fixtures. Tungsten lights around 3200K look much warmer by comparison.

• A. Adjusting the exposure of the image
• B. Setting the sharpness of the lens
• C. Neutralizing the color cast of the light source so whites appear white ✓
• D. Controlling the depth of field

Why: White balance tells the camera what color counts as neutral white under the current lighting. Correct white balance removes unwanted color casts so that white objects render as white rather than tinted orange or blue.

• A. Around 3200K ✓
• B. Around 5600K
• C. Around 9000K
• D. Around 1000K

Why: Tungsten studio lamps are generally rated around 3200K. This warm light is why tungsten-balanced film or a tungsten white balance setting is used when shooting under these lamps.

• A. The image becomes overly blue or cool ✓
• B. The image becomes overly orange or warm
• C. The image becomes sharper
• D. The image becomes darker without any color shift

Why: Using a tungsten (warm) white balance on daylight (cool) light tells the camera to add warmth to compensate, but since the source is already cool, the result is an overly blue image. The reverse mismatch produces an orange cast.

• A. To record the camera settings used on each day of shooting
• B. To itemize every shot needed to tell the story, organized for efficient filming
• C. To track the budget spent on equipment rentals
• D. To list the actors' contact information and availability

• A. The insurance policy protecting equipment on set
• B. The variety of camera angles and shot sizes captured for a scene so it can be edited flexibly
• C. The total running time of the finished film
• D. The lighting setup used to illuminate the set evenly

• A. Extreme close-up
• B. Insert shot
• C. Establishing shot
• D. Dutch angle

• A. It is the cheapest shot to film and saves money
• B. It captures the entire action of the scene in one continuous take, giving the editor a reference for timing and blocking
• C. It is required by union rules for every production
• D. It always uses the widest lens available for maximum sharpness

• A. It doubles the number of shots that can be captured per setup
• B. It keeps spatial relationships between characters consistent so the audience can follow the scene without disorientation
• C. It eliminates the need for lighting adjustments between shots
• D. It allows the camera to move freely across the entire set without limits
