• 1/2000 sec

• 1/30 sec

• Aperture

• Shutter Speed

• ISO

• All three

In order to get the fastest possible shutter speed, at a given ISO when using aperture priority, you must...

• Set the lens aperture to its widest opening

• Set the lens aperture to its smallest opening

• Set the shutter to its highest setting

If your image is overexposed when taking an image of a fast-moving subject using the widest aperture, what can you do to reduce the exposure?

• Neither

When describing the hole in the lens, which is the correct term to use?

• It will be overexposed

If you are using the widest aperture, what would you have to increase in order to be able to freeze a fast-moving subject inside the classroom?

• The shutter speed

• The ISO

What is the drawback of using a high ISO?

• Your image will be overexposed

• Your image will be underexposed

• The image will show digital noise

When should you use a high ISO?

• When there is insufficient light to hold the camera steady

• When there is too much light

• When the shutter speed is too high

The difference between two f numbers is called...

• A stop

• A step

• A shutter speed
