1. Aperture - What is Apeture

What is the aperture in photography analogous to in the human body?

• The pupil

• The lens of the eye

• The retina

• The iris

How is aperture expressed in photography?

• In millimeters

• In f numbers or f stops

• In degrees

• In lumens

What effect does a larger aperture (smaller f number) have on depth of field?

• Increases depth of field

• Has no effect on depth of field

• Decreases depth of field

• Makes the entire image blurry

What is the significance of the maximum aperture of a lens?

• Measures the lens' durability

• Determines the lens' focal length

• Shows the speed of the lens

• Indicates the lens' zoom capability

Why are lenses with apertures of f1.4 or f2.8 considered fast lenses?

• Because they can zoom in quickly

• Because they can focus faster

• Because they allow for faster shutter speeds

• Because they are lighter and easier to carry

What is the main disadvantage of using a lens at its minimum aperture?

• It increases motion blur

• It reduces the camera's ISO

• It causes the image to lose clarity due to diffraction

• It overexposes the photograph

How does the maximum aperture of a zoom lens typically change with focal length?

• It decreases, allowing less light

• It increases, allowing more light

• It remains constant

• It varies unpredictably

What camera mode allows you to manually adjust the aperture while it automatically sets shutter speed and ISO?

• Program mode

• Shutter priority mode

• Aperture priority mode

• Manual mode

What is the effect of a larger aperture (smaller f number) on shutter speed and ISO?

• Allows for a faster shutter speed or lower ISO

• Requires a faster shutter speed and higher ISO

• Allows for a slower shutter speed and higher ISO

• Has no effect on either

What type of photography benefits most from lenses with large apertures?

• Nighttime photography

• Macro photography

• Portrait photography

• Landscape photography
