VIS301 Quiz #5 (V2)

What is the primary function of a lens in a camera?

• To provide digital zoom

• To gather and focus light onto the sensor or film

• To change the resolution of the image

• To control the exposure of the scene

Which of the following describes a telephoto lens?

• A lens with a focal length shorter than normal, offering a wide field of view

• A lens with a fixed focal length, often used for portrait photography

• A lens with a focal length longer than normal, magnifying and narrowing the angle of view

• A lens with variable focal length

How does the f-stop number affect the aperture size?

• Higher f-stop numbers result in larger apertures

• Higher f-stop numbers result in smaller apertures

• Lower f-stop numbers reduce the amount of light entering the lens

• F-stop numbers do not affect aperture size

Which of the following lenses is best for creating a dramatic depth-of-field effect?

• Wide-angle lens

• Telephoto lens

• Prime lens with a low f-stop number

• Zoom lens with a high f-stop number

What is the main advantage of using a prime lens over a zoom lens?

• Prime lenses are always lighter

• Prime lenses offer a sharper image and larger maximum aperture

• Prime lenses are less expensive than zoom lenses

• Prime lenses are easier to carry

What is the difference between angle of view (AOV) and field of view (FOV)?

• AOV is the area captured by the lens, and FOV is the area seen through the camera

• AOV depends on focal length, while FOV depends on sensor size

• AOV is the horizontal range of vision, and FOV is the vertical range of vision

• There is no difference between AOV and FOV

What is diegetic sound in film?

• Sound that comes from an off-screen source

• Sound that exists within the story world of the film

• Background music added in post-production

• Sound effects synchronized with on-screen actions

What is the purpose of room tone in sound design?

• To mask dialogue inconsistencies

• To provide a clean, noise-free recording

• To create consistency in ambient background sound between cuts

• To replace non-diegetic sounds

Which of the following describes foley sound?

• Pre-recorded sound effects from a library

• Sound effects recorded live on set during production

• Custom sound effects recorded in synchronization with the film’s visuals

• Music tracks layered into the final mix

What is the difference between synchronous and non-synchronous sound?

• Synchronous sound is recorded in post-production, and non-synchronous sound is recorded live

• Synchronous sound matches on-screen actions, while non-synchronous sound does not

• Synchronous sound is always diegetic, and non-synchronous sound is always non-diegetic

• There is no difference between synchronous and non-synchronous sound
