The Big Three: Aperture, Shutter, ISO

What does the aperture control in a camera?

• The amount of light that enters the camera

• The depth of field

• Both the amount of light and the depth of field

• None of the above

How is the lens aperture specified?

• As the ratio of focal length to the aperture diameter

• As the size of the aperture opening

• As the amount of light entering the camera

• As the depth of field

What does a lower f number mean?

• A smaller aperture opening

• A larger aperture opening

• Less light entering the camera

• More light entering the camera

What does the shutter speed control?

• The amount of light that enters the camera

• The depth of field

• The duration of light entering the camera

• The ISO setting

When would you use a fast shutter speed?

• In sports/action photography to freeze motion

• In low light conditions to capture more light

• In landscape photography to increase depth of field

• In portrait photography to create a shallow depth of field

What does the S/Tv setting on a camera represent?

• Shutter speed priority

• Aperture priority

• ISO priority

• Manual mode

What does ISO control in photography?

• The amount of light that enters the camera

• The depth of field

• The look of a photograph in different lighting conditions

• The shutter speed

What is the risk of adjusting the ISO?

• Adding noise to the photograph

• Decreasing the depth of field

• Increasing the shutter speed

• Changing the focal length

What does noise in a photograph refer to?

• A blurry effect

• A pixelated look

• A lack of sharpness

• An overexposed image

What happens to the amount of noise in an image as the ISO increases?

• The noise decreases

• The noise increases

• The noise remains the same

• The noise depends on the aperture
