Depth of Field Test

Depth of Field Test

The first part tests your knowledge of the basic principles of depth-of-field while the second part tests your ability to accurately guess the amount of depth-of-field with a real-world situation.This test is divided into two parts.

Best of luck!

Basic Principles

• 1. Which camera or lens setting has no effect on depth-of-field?

  •  T-Stop
  •  ISO
  •  Focal Length
  •  Format

• 2. When a point in the subject or scene registers also as a point on film or video, it is referred to as being __________.

  •  Within the zone
  •  Within the frame
  •  Inside the circle of confusion
  •  In critical focus

• 3. True or false: the size of the finished film or video image (projected, TV, Internet) has an effect on acceptable focus?

  •  True
  •  False

• 4. What is the approximate ratio of depth-of-field in front of and behind a subject you are focused on?

  •  1/3 in front; 2/3 behind
  •  1/2 in front; 1/2 behind
  •  2/3 in front; 1/3 behind
  •  3/4 in front; 1/4 behind

• 5. What is the closest distance at which the far limit of depth-of-field extends to infinity called?

  •  Superfocal Distance
  •  Infinity Range
  •  Critical Focus
  •  Hyperfocal Distance

• 6. Stopping down the lens __________ depth-of-field.

  •  Has no effect on

• 7. Opening up the iris of a lens __________ depth-of-field.

  •  Increases
  •  Decreases
  •  Has no effect on

• 8. Getting closer to the subject you’re focusing on __________ depth-of-field.

  •  Increases
  •  Decreases
  •  Has no effect on

• 9. Adding a filter in front of the lens without adjusting the exposure __________ depth-of-field.

  •  Increases
  •  Decreases
  •  Has no effect on

• 10. Using a 35mm film camera as opposed to a 16mm film camera for the exact same shot would cause depth-of-field to __________.

  •  Increase
  •  Decrease
  •  Stay the same

Guess the Depth-of-Field

In this section, you are given a situation and must guess the depth-of-field you have. You may assume that the camera is shooting 24 frames-per-second with a 180-degree shutter.
