Welcome to your Lesson 4: Controlling Motion
1. The shutter speeds serve two purposes - what are they?
A. To control motion and control depth of field

C. To control the amount of light that reaches the sensor and depth of field
2. What is the slowest shutter speed that you should use if you are hand-holding your camera?
A. 1/60 with a 200mm lens
B. 1/125 with a 28mm lens
C. 1/60 with a 50mm lens
D. 1/60 with a 100mm lens
3. Why would you want to change the shutter speed from 1/60 to 1/250?
A. To increase the depth of field
B. To use a slower shutter speed
C. To "freeze" a moving object
D. To "blur" a moving object
4. Which line has the “whole” shutter speeds in the correct order?

A. Decreases
B. Increases
C. Stays the same
6. If you move the shutter speed from 1/60 to 1/30, what happens to the amount of light that reaches the sensor?

A. 1/125
B. 1/250
C. 1/500
D. 1/60
9. How much more light reaches the sensor when you move from F8 to F4?
