  • 1. Know your Camera Essential Settings *Adapted from Travis Feil’s presentation
  • 2. Photoshop can t do it all…  It is true that Photoshop can do amazing things.  However, the more you know before you take the shot, the better your pictures will turn out.  Advanced cameras like the ones we use can take great pictures in the fully automatic mode, but your pictures will be better if you adjust settings manually.  There are three basic features you should master in order to take great pictures. Finding the correct balance of these three features will help you achieve great photography.

  • 15. Glossary Time  Exposure: –  Refers to the correct lighting of all objects in a photograph.
  • 16. Underexposure  Too dark  Lacks definition  Details lost
  • 17. Overexposure  Too bright  Lacks details  Definition lost  Overblown
  • 18. Proper Exposure  Just right lighting  Defined details
  • 19. Glossary Time  Metering: –  Using the camera s metering scale to determine correct exposure. –  Your camera tells you the settings to use!
  • 20. Glossary Time  ISO: –  The camera s sensitivity to light. –  Also known as film speed for those who have actually used real film. –  Useless info in case you re curious: ISO is from International Standards Organization originally ASA from American Standards Association. They just made sure all film, no matter where it was made or purchased, was properly labeled.
  • 21. Glossary Time  ISO:
  • 22. Glossary Time  Shutter speed: –  The speed at which the camera s eye opens and closes.
  • 23. Glossary Time  Shutter speed:
  • 24. Glossary Time  Aperture: –  The size of the eye in the camera. –  Most commonly known as F-Stop
  • 25. Glossary Time  Aperture:
  • 26. Each Word Matters  So far we ve defined –  Exposure –  ISO –  Shutter Speed –  Aperture  Now let s see how they affect pictures.
  • 27. ISO  Sensitivity to light.  Displayed as a whole number: 100 –  200 –  400 –  800 –  1600 –  3200 –   Lower numbers mean –  less sensitive = less exposure = less light = darker pictures  Higher numbers mean –  more sensitive = more exposure = more light = brighter pictures

  • 29. ISOWhat s theISO on thiscameraright now?
  • 30. ISO  DOES affect image quality. –  Higher ISO = grain and noise  Will probably remain the same for the whole shoot unless lighting changes.  Use the lowest setting possible.  Set it and forget it.
  • 31. ISO  To properly expose an image in… …bright, natural light, use ____ ISO. …dimly lit situations, use a ____ ISO
  • 32. ISO  To properly expose an image in… …bright, natural light, use LOW ISO. …dimly lit situations, use a HIGH ISO
  • 33. ISO  On a bright sunny day, an ISO of 1600 will probably make my pictures turn out… …completely white (over exposed) …completely dark (under exposed)
  • 34. ISO  On a bright sunny day, an ISO of 1600 will probably make my pictures turn out… …completely white (over exposed) …completely dark (under exposed)
  • 35. ISO  Ina dimly lit classroom, an ISO of 100 will probably produce an image that is… …completely white (over exposed) …completely dark (under exposed)
  • 36. ISO  Ina dimly lit classroom, an ISO of 100 will probably produce an image that is… …completely white (over exposed) …completely dark (under exposed)
  • 37. Shutter Speed  The speed at which the eye blinks.  Whenyou push the shutter release button, the internal eye opens and closes to let light in and create an image.  The amount of light that gets in affects exposure.
  • 38. Shutter Speed
  • 39. Shutter Speed  Usually appears as a fraction but might be a whole number on the screen. Refers to a fraction of 1 second. 30 (30 seconds - slow blink ) 4 (4 seconds) 1/80 (one 80th of one second) 1/250 (one 250th of one second) 1/500 (one 500th of one second) 1/4000 (one 4000th of one second - fast blink )
  • 40. Shutter Speed  Think exposure… –  If I leave the eye open for 30 seconds, my image will be… …brighter (over exposed) …darker (under exposed)
  • 41. Shutter Speed  Think exposure… –  If I leave the eye open for 30 seconds, my image will be… …brighter (over exposed) …darker (under exposed)
  • 42. Shutter Speed  Think exposure… –  If I only leave the eye open for 1/1000 of 1 second, my image will be… …brighter (over exposed) …darker (under exposed)
  • 43. Shutter Speed  Think exposure… –  If I only leave the eye open for 1/1000 of 1 second, my image will be… …brighter (over exposed) …darker (under exposed)
  • 44. Shutter SpeedWhat is the shutter speed on this cameraright now?(Ignore thered box -that isn t it.)
  • 45. Shutter SpeedWhat is the shutter speed on this cameraright now?
  • 46. Shutter Speed  In addition to exposure… –  A slower shutter speed (lower number) can create blur in the action. –  A faster shutter speed (higher number) freezes quick action. –  1/60 can capture good still frames. –  1/500 will stop a tennis racquet in swing.
  • 47. Shutter SpeedVERY Slow shutter speed - people haveto stand still. A tripod should be used to preventthe subject from being blurry.1/60 orLower=tripod
  • 48. Shutter SpeedFast shutter speedstops action.
  • 49. Shutter SpeedFast shutter speed stops action.
  • 50. ISO + Shutter Speed  Thinkabout the relationship between the 2 settings we ve discussed. –  If you increase ISO, your picture will become lighter or overexposed. –  You can increase shutter speed to balance that and make your picture darker…back to what it needs to be for proper exposure. –  It s like a teeter-totter.
  • 51. ISO + Shutter Speed  Thinkabout the relationship between the 2 settings we ve discussed. –  If your ISO is low, your image will be darker. –  You can decrease shutter speed to let in more light and make the image brighter.
  • 52. ISO + Shutter Speed  Lower shutter speed creates blur of the Benton player.  Low shutter speed lets in too much light.  ISO must be adjusted down to compensate.  IS0 = 200  Shutter Speed = 1/200
  • 53. Aperture (F-Stop)  The size of the eye that blinks.  This setting is backwards or counterintuitive. The lower the F-Stop number, the bigger the eye. –  F3.5 = big eye –  F21 = little eye  The bigger the eye, the greater the exposure (more light gets in).
  • 54. Aperture (F-Stop)  Appears as an F-Number combination  The lower the number, the bigger the eye. –  F 3.5 (big opening, lots of light, more exposure) –  F6 (medium opening, medium light) –  F 11 (small opening, little light)
  • 55. Aperture (F-Stop)
  • 56. Aperture  Think exposure… –  If I have a big eye (low F-Stop), my image will be… …brighter (over exposed) …darker (under exposed)
  • 57. Aperture  Think exposure… –  If I have a big eye (low F-Stop), my image will be… …brighter (over exposed) …darker (under exposed)
  • 58. Aperture  Think exposure… –  If I have a small eye (high F-Stop), my image will be… …brighter (over exposed) …darker (under exposed)
  • 59. Aperture  Think exposure… –  If I have a small eye (high F-Stop), my image will be… …brighter (over exposed) …darker (under exposed)
  • 60. Aperture  What is the aperture setting on this camera right now?
  • 61. Aperture  What is the aperture setting on this camera right now?
  • 62. Aperture  An F4.0 will let in… –  Lots of light –  Little light
  • 63. Aperture  An F4.0 will let in… –  Lots of light –  Little light
  • 64. Aperture  In addition to exposure, aperture affects depth of field. –  Shallow Depth of Field = subject in focus but background blurred.   Small F-Stop number –  Greater Depth of Field = All objects in focus   Larger F-Stop number
  • 65. Aperture  Lower F-Stop (3.5) = blurred background
  • 66. Aperture  Lower F-Stop (3.5) = blurred background
  • 67. Aperture  Higher F-Stop (16) = all in focus
  • 68. Aperture  Higher F-Stop (16) = all in focus
  • 69. Aperture + ISO + Shutter Speed  Think about the relationship of all the settings together… –  If I want to blur a background, my F-Stop must be low. –  This causes a bigger eye which lets in more light and may cause my picture to be over exposed. –  There are 2 adjustments I can make to solve the problem…   Decrease ISO   Increase Shutter Speed
  • 70. Aperture + ISO + Shutter Speed  Think about the relationship of all the settings together… –  If I want a crisp foreground AND background, my F-Stop will be higher. –  This causes a smaller eye which lets in less light and may cause my picture to be under exposed. –  There are 2 adjustments I can make to solve the problem…   IncreaseISO   Decrease Shutter Speed
  • 71. Aperture + ISO + Shutter Speed  Each setting change affects exposure.  Each setting change affects the other settings.  Ifyou understand what each one does, you can take better pictures.
  • 72. Making Pictures v. Taking Pictures  First, consider your lighting conditions: the type of light you re shooting in, the direction its coming from, etc.  Set your ISO to the lowest possible setting for those conditions.  Visualize the image you want and set the camera for those priorities.
  • 73. Aperture + ISO + Shutter SpeedConditions: dimly lit tunnels.RequireshigherISO1600
  • 74. Aperture + ISO + Shutter SpeedDesired shot: Bulb in focus, background blurred.RequiresExtremely slowshutter speedBulb settingor 1/4
  • 75. Aperture + ISO + Shutter SpeedCompensation: with such a high ISO and slow shutterspeed, the image is WAY overexposed.To balance,increaseF-StopEye is smallerless lightgets in!
  • 76. Aperture + ISO + Shutter SpeedConditions: very sunny day, outdoorsLow ISO - noneed for an overlysensitive camera200
  • 77. Aperture + ISO + Shutter SpeedDesire shot: selective focus backgroundRequires lowF-Stop -3.5Causes image tobe over exposedbecause the eyeis so large
  • 78. Aperture + ISO + Shutter SpeedCompensation: increase shutter speedDecrease the timethe camera isexposed to light1/1000Balances the effectsof large aperture
  • 79. Aperture + ISO + Shutter SpeedConditions: outdoors inlow shadeMedium-range ISO600
  • 80. Aperture + ISO + Shutter SpeedDesired shot: Blurry background,focus on the subjectRequires low F-Stop to blurbackground. F5.6Requires medium shutter speed toensure subject (young child) is in focusEven though she was moving. 1/400
  • 81. Aperture + ISO + Shutter SpeedCompensation: if F5.6 with a1/400 shutter speed does notexpose properly, adjust ISO.
