Exposure Triangle Part Two

What does a "stop" represent in photography?

• A specific f-number value

• A fixed shutter speed

• A doubling or halving of the amount of light

• A specific ISO sensitivity

If you change your aperture from f/16 to f/11, how should you adjust the shutter speed to maintain a good exposure?

• Change the shutter speed from 1/125s to 1/60s

• Change the shutter speed from 1/125s to 1/250s

• Change the shutter speed from 1/125s to 1/500s

• Keep the shutter speed at 1/125s

If the ambient light decreases by two stops and your aperture and shutter speed are fixed, what adjustment should be made to the ISO to maintain proper exposure?

• Decrease ISO from 100 to 50

• Increase ISO from 100 to 200

• Increase ISO from 100 to 400

• Increase ISO from 100 to 800

What is the general rule for maintaining a balanced exposure when adjusting settings in the exposure triangle?

• Always adjust the shutter speed first, then aperture

• If one setting is changed by a stop, another setting must be changed by a stop in the opposite direction

• Only ISO should be adjusted to compensate for light changes

• All three settings (shutter, aperture, ISO) must always be changed simultaneously
