Text of The Digital Camera Basic Photographic Principles: Shutter Speed & Aperture Setting

  • Slide 1
  • The Digital Camera Basic Photographic Principles: Shutter Speed & Aperture Setting
  • Slide 2
  • Some Basic Photographic Principles Correct exposure is the result of the right balance between the shutter speed and the aperture
  • Slide 3
  • Shutter Speed Is the speed at which the shutter opens and closes when it lets in the light speed to capture the image The speed you need depends on the light available and the subject
  • Slide 4
  • A landscape image would not require a very fast shutter speed. Slower speed
  • Slide 5
  • A higher speed is needed for a fast action shot like a football game. High Speed
  • Slide 6
  • Aperture The aperture is the size of the hole through which the lights passes This size will dictate the depth of field in a photograph
  • Slide 7
  • Depth of field: Is the area that is still sharp in front of and behind the focused point. Depth of field is the amount of distance between the nearest and farthest objects that appear in acceptably sharp focus in a photograph.
  • Slide 8
  • Depth of Field It influences the look of the picture: crisp & sharp? Highlight the subject? Functions: Portrait, Landscape, and Action help control this
  • Slide 9
  • Aperture Ring: f stops The aperture is described in fstops the number is opposite in proportion to its size.
  • Slide 10
  • Small Aperture = Overall Focus A small or narrow aperture will give an image sharp focus from foreground to background represented as a high number.
  • Slide 11
  • f/ 8.0f/5.6f/2.8
  • Slide 12
  • Large Aperture Isolates the Subject A large or wide aperture isolates the subject, with the background and foreground out-of-focus represented by a low number.
  • Slide 13
  • ACTIVITY finding Examples. Use the link below and add 8 more slides to demonstrate your understanding of f stop and depth of field while reviewing the categories of photography for NEXT WEEKS TEST! Title slides to show your chosen category and f stop 1. Photojournalism find 1 low f stop and 1 high 2. Social Documentary find 1 low f stop and 1 high 3. Documentary find 1 low f stop and 1 high 4. Art Photography find 1 low f stop and 1 high http://boston.com/bigpicture
