It relates to the sensitivity of a digital camera's sensor to available light.
What are the four factors that affect photographic images?
2. Shutter Speed
What are the two types of light?
What does shutter speed do?
Shutter speed controls the duration of time light is permitted to strike the sensor.

Control Depth of Field
True or False: Small apertures, f 11 - f 22, provide a deep depth of field?

International Organization for Standardization
Higher ISOs allow for faster or slower shutter speeds?
True or False: The lower the ISO setting the less sensitive the camera's sensor is to light.

What ISO provides for superior image quality and minimization of digital noise?
A lower ISO, like 100 or 200.
