  12. 13. Aperture, Shutter Speed and Film Speed Joel Kinison
  13. 14. Exposure Settings <ul><li>Aperture </li></ul><ul><li>Shutter speed </li></ul><ul><li>Film speed- ISO </li></ul>International Standard Organization
  14. 15. The Window: Imagine <ul><li>1 . Aperture is the size of the window. If it’s bigger more light gets through and the room is brighter. </li></ul>
  15. 16. <ul><li>2. Shutter Speed is the amount of time that the shutters of the window are open. The longer you leave them open the more comes in. </li></ul>
  16. 17. <ul><li>3. Now imagine that you’re inside the room and are wearing sunglasses. Your eyes become desensitized to the light that comes in (it’s like a low ISO ). </li></ul>
  17. 18. The Big Three <ul><li>http://video.google.com/videosearch?q=enjoying%20digital%20photography&oe=utf-8&rls=org.mozilla:en-US:official&client=firefox-a&um=1&ie=UTF-8&sa=N&tab=wv# </li></ul>
  18. 19. Aperture (f-stops) <ul><li>Aperture refers to the size of the opening inside the lens that the light must go through to reach the film. Aperture is measured in f/stops as indicated in the series below: </li></ul><ul><li>1, 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, 32, 45 </li></ul>
  19. 20. Aperture (f-stops)
  20. 21. Depth of Field <ul><li>Used to describe the region in front and behind the focus point that appears sharp in the final photograph. </li></ul><ul><li>It is controlled by lens length, subject distance, and aperture setting. </li></ul>
  21. 22. Depth of Field
  22. 24. Pg. 22-23
  23. 25. Shallow Depth of Field
  24. 26. Large Depth of Field
  25. 27. See the Difference
  26. 29. Depth of Field Preview <ul><li>A 'depth of field preview' button is one that closes down the aperture without engaging the mirror or shutter. </li></ul><ul><li>Using the DOF button, you can see what will be sharp in the final photograph. </li></ul>
  27. 30. Shutter Speeds <ul><li>The shutter-speed selector controls the length of time that the shutter remains open. </li></ul><ul><li>Understand that each progression represents half as much light as the preceding number. Common shutter settings are as follows: </li></ul><ul><li>1 second, 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125, 1/250, 1/500, 1/1000, and 1/2000 second. </li></ul>
  28. 31. Shutter Operation
  29. 32. Shutter Speed Pg.18-21 Use it creatively
  30. 33. Waterfalls Example
  31. 34. Shutter Speed and Sharpness <ul><li>When hand holding your camera, be sure that your shutter speed is fast enough to produce a sharp photo. </li></ul><ul><li>1/60 </li></ul>
  32. 35. Film Speed <ul><li>Film Speed Rating - ISO All film has a speed rating, whether digital or traditional. The ISO rating describes how quickly the film reacts to light. </li></ul><ul><ul><li>Film speed uses stops, just like shutter and aperture For example, going from ISO50 to ISO200 buys you 2 stops more light. </li></ul></ul>
  33. 36. Film Speed
  34. 37. ISO guidelines you can follow
  35. 38. Trade Offs in Exposure Settings <ul><li>Large and small apertures (small f/ratio numbers) are subject to lens unsharpness. </li></ul><ul><li>Aperture determines the depth of focus. </li></ul><ul><li>Long exposure times require a tripod, and will usually blur the photo if you photograph moving subjects. </li></ul><ul><li>Low film sensitivities (low ISO number) require longer exposures. </li></ul>
  36. 39. Exposure Calculator <ul><li>http://www.robert-barrett.com/photo/exposure_calculator.html </li></ul>
  37. 40. Flickr Favorites <ul><li>http://www.flickr.com/photos/seanettles/favorites/ </li></ul>
  38. 41. So What Does This Mean? <ul><li>Pg.24-25 </li></ul><ul><li>Blur vs DOF </li></ul>
  39. 42. Mode Dial <ul><li>Basic Zone (Pre-Sets) </li></ul><ul><li>Portrait Mode </li></ul><ul><li>Landscape Mode </li></ul><ul><li>Night Scene (portrait) Mode </li></ul><ul><li>Black and White Mode </li></ul><ul><li>Macro (close up ) Mode </li></ul><ul><li>Sports Mode </li></ul><ul><li>Creative Zone </li></ul><ul><li>P - Program </li></ul><ul><li>TV - Shutter priority </li></ul><ul><li>AV - Aperture priority </li></ul><ul><li>M - Manual </li></ul>
  40. 43. Mode Dial <ul><li>Basic Zone (Pre-Sets) </li></ul><ul><li>Portrait Mode Use this mode when you want a subject in the foreground in sharp focus. </li></ul><ul><li>Landscape Mode Use this mode when you want a wide-angle shot with the background in focus. </li></ul><ul><li>Night Scene (portrait) Mode Use this mode when you're shooting a subject at night. Illuminates the subject with the flash, while keeping the shutter open longer to provide more light for the background. Creates a balance. </li></ul><ul><li>Black and White Mode Use this mode to take pictures in black and white </li></ul><ul><li>Macro (close up ) Mode Use this mode for extreme close-ups. Blurs the background, narrow DPF. </li></ul><ul><li>Sports Mode For shooting scenes with lots of motion, which you want to capture without blurring . </li></ul>
  41. 44. Mode Dial <ul><li>Creative Zone </li></ul><ul><li>P - Program - Program mode is much like Automatic mode - the camera will still do most of the setup work for you -- but it allows you to manually override some settings </li></ul><ul><li>TV - Shutter priority - used for manual shutter speed </li></ul><ul><li>AV - Aperture priority - used for manual aperture </li></ul><ul><li>M - Manual - used for fully manual control This allows you to manually adjust both shutter speed and aperture for the same shot, as well as focus. </li></ul><ul><li>A-DEP = Auto depth of field* </li></ul>
  42. 45. Respond to Photograph <ul><li>Pg. 170-171 </li></ul>
  43. 46. Assignment <ul><li>Take a photo using the Creative Mode, and explain the effect on the exposure. </li></ul><ul><li>Reading </li></ul>http://www.flickr.com/photos/jnovek/2528932423/
