Exposure Triangle Quiz (20 Questions)

Which exposure setting controls the size of the lens opening?

• ISO

• Aperture

• Shutter Speed

• White Balance

What does a wide aperture (f/1.8) do compared to a narrow aperture (f/16)?

• Lets in less light, deep depth of field

• Lets in more light, shallow depth of field

• Increases motion blur

• Adds noise to the image

An f/2.8 aperture compared to f/5.6 will:

• Halve the light entering the lens

• Double the light entering the lens

• Not change brightness

• Reduce ISO

What’s the side effect of using a very small aperture (like f/22)?

• Motion blur

• High noise

• Increased depth of field but possible diffraction softness

• Overexposure

Which setting determines how long the camera sensor is exposed to light?

• ISO

• Aperture

• Shutter Speed

• Focus

What happens when you use a slow shutter speed (like 1 second)?

• Less light enters

• Motion blur increases

• Depth of field decreases

• ISO increases

What shutter speed is generally needed to freeze fast action (like sports)?

• 1/30 sec

• 1/60 sec

• 1/500 sec or faster

• 2 seconds

If you double the shutter speed (from 1/250 to 1/500), how much light enters?

• Twice as much

• The same

• Half as much

• Four times as much

What does ISO control in the exposure triangle?

• A) Aperture size

• B) Sensor sensitivity to light

• C) Shutter speed

• D) Color saturation

What’s the trade-off of using a high ISO (like ISO 6400)?

• Shallow depth of field

• Increased image noise/grain

• Motion blur

• Underexposure
