Understanding Aperture

What is aperture?

• The hole in the lens through which light travels into the camera body

• The size of the pupil in the human eye

• The maximum aperture of a lens

• The speed of the lens

What is the function of the diaphragm in a lens?

• To control the size of the aperture

• To gather light and bend it inward

• To block all light except the light that goes through the aperture

• To determine the depth of field

How is aperture expressed in photography?

• In f-numbers

• In ISO values

• In shutter speeds

• In focal lengths

What does a larger aperture (smaller f-stop) mean?

• More light enters the camera

• Less light enters the camera

• A larger depth of field

• A smaller depth of field

What is the maximum aperture of a lens?

• The smallest f-number

• The largest f-number

• The speed of the lens

• The minimum aperture

Why are lenses with larger maximum apertures considered fast lenses?

• They can pass more light into the camera

• They have a smaller depth of field

• They have a larger focal length

• They have a faster shutter speed

What is the impact of aperture on the depth of field?

• A large aperture brings all foreground and background objects into focus

• A small aperture isolates either the foreground or background objects

• A large aperture makes everything blurry

• A small aperture sharpens out-of-focus areas

What is the advantage of using a fast lens in night photography?

• It allows for faster shutter speeds

• It reduces the amount of noise in the image

• It increases the depth of field

• It improves the clarity of the image

What type of lens has a fixed focal length?

• Prime lens

• Zoom lens

• Variable aperture lens

• Wide-angle lens

Which mode allows manual adjustment of aperture values?

• Aperture priority mode

• Shutter priority mode

• Program mode

• Auto mode
