STEP 1 - LEARN

• In this lesson, you will learn about using
  aperture and shutter speed while taking photos.

3
APERTURE

• Size of the shutter hole
• Also called f-stop (example f/3.5)
• Allows more or less light in
• Controls Depth of Field (Background Blur)

APERTURE

• The larger the opening of the aperture, the
  smaller the number set on your camera.
• Setting your DSLR to the AV setting allows you to
  control aperture while the camera auto sets the
  others.
• Larger apertures (smaller numbers) allow for a
  smaller depth of field, limiting the objects in
  focus.

SHUTTER SPEED

• How long the shutter stays open
• Measured in 1/x of a second
• Faster Stop Action (Sports), less light
• Slower more light, blur
• The bigger the denominator, the faster the speed
  (ie 1/1000 is much faster than 1/30)

SHUTTER SPEED

• Setting your camera to the TV mode allows you to
  control the shutter speed while the camera auto
  sets the other controls.

11
STEP 2 - PRACTICE

• By the end of class today, take two photos that
  demonstrate thought and understanding of aperture
  and shutter speed.

12
PRACTICE APERTURE SHUTTER SPEED

• Photo 1 Change the aperture (f/stop) settings on
  the camera and take a photo that demonstrates
  shallow depth of field.
• Photo 2 Change the shutter speed (1/X) settings
  on the camera to capture a subject in action.
• Dont forget to use photo composition techniques
  like Rule of Thirds, birds/worms-eye view, etc!

STEP 3 - DO

• Over the course of the next week, take four
  photos, to be used in the yearbook, that
  demonstrate your understanding of aperture and
  shutter speed.

APERTURE SHUTTER SPEED

• Photos 1 2 Each must demonstrate the use of
  aperture to make the Center of Visual Interest
  (CVI) stand out.
• Photos 3 4 Each photo must demonstrate the use
  of shutter speed to stop a subject in motion.
• Write down the aperture/shutter speed you used
  for each photo and create a caption for each that
  includes the setting.
• Submit your photos electronically using
  PowerPoint, Prezi or Google Slides.
