Shutter speed and aperture are tools that photographers can adjust to control the amount of light entering the camera and how motion is depicted. Shutter speed refers to how long the shutter is open and impacts whether motion is frozen, blurred, or has a sense of movement. Aperture, measured in f-stops, controls the size of the lens opening and determines depth of field. Photographers are challenged to create a series of photos telling a narrative story using different shutter speeds to show stopped, blurred, and panned action.

Shutter Speed
and Aperture

2. Shutter speed is simply a measure of how long the shutter
stays open when you take your picture.
• shutter speed is measured in fractions of seconds.
• the faster the shutter speed, the less light will hit the film.

4. Stop action
Blurred action
Panned action

5. Stop action
• subject and background are frozen
• fast shutter speed
(1/500, 1/1000, 1/2000 second)
• peak of action

6. Blurred action
• blurred subject, frozen background
• slow shutter speed
(1/15, 1/8, 1/4, 1/2 second)
• brace the camera!

7. Panned action
• frozen subject, streaked background
• slow shutter speed
(1/15, 1/8, 1/4, 1/2 second)
• camera moves with the moving subject

8. Panning
Move the camera with the subject as it
crosses the field of view of your camera,
and you snap the shot as you move the
camera with the subject.

35. Aperture size is measured in f-stops.
F-stops represent the amount of light going into the camera.
The higher the f-Stop number, the less light.
Aperture (lens opening)

36. Lens aperture controls Depth of Field
Great depth of field
large range of distances in focus
Shallow depth of field
limited range of distances in focus

37. Aperture and shutter speed:
both control the amount of light that reaches the film for an exposuren
The faster the shutter speed is, the less light will hit the film.
2 4 8 15 30 60 125 250 500 1000
The higher the f-stop number, the less light will hit the film

60. Photo Narrative
Make a series of photographs that depict a scene or event which could
be real or imagined.
Turn in three photographs in a narrative series.
•One photo must show stopped action using a fast shutter speed.
•One photo must show blurred action using a slow shutter speed.
•One photo must show panned action using a slow shutter speed.
Each image must represent the beginning, middle, or end of the series.
