Basic Exposure Controls

SHUTTER SPEEDS

APERTURE / F-STOPS

ISO SENSITIVITY


ISO Setting - Controls the sensitivityof the sensor

ISO Sensitivity

-Lower number for brighter situations

(100, 200iso)

-Use a higher number for darker situations

(400, 800, 1600iso)

Higher number = more sensitivity = grain and noise in digital files


Higher the number, more grain and artifacts

ISO Sensitivity


  • Aperture – controls the amount of light coming thru the lens

  • Little opening, “Big Honking Hole”!

  • Designated in “f-stops” f2.8, f4.0, f5.6, f8, f11, 16, f22

  • -Smaller opening for brighter situations

  • (f8, f11, f16, f22)

  • -Wider opening for darker situations

  • (f2.8, f4. f5.6)

  • Aperture orf-stops


    Aperture orf-stops

    -Smaller opening for brighter situations

    (f8, f11, f16, f22)

    -Wider opening for darker situations

    (f2.8, f4. f5.6)


    Aperture also determines the depth of field

    Or, what’s in focus from front to back

    Aperture orf-stops


    Shutter Speedscontrols how fast the shutter opens and closes

    Designated by shutter speed dial or menu; 60th, 125th, 250th, 500th

    -Faster shutter speed freezes action (500th, 1000th, 2000th, etc)

    -Slower shutter speed for highlighting motion (30th, 60th, etc)


    Shutter Speedscontrol how fast the shutter opens and closes

    @ f 16

    Designated by shutter speed dial, menu: 60th, 125th, 250th, 500th

    Shutter speed also freezes or blurs the action!

    1/30th or less


    ISO + Shutter Speed + Aperturebalanced togetherdetermine proper exposure

    “Sunny 16 Rule?”


    How will I know I have reached exposure Nirvana?

    What’s Proper Exposure?


    What’s All The Crap In My Viewfinder??

    But I’m using the GREEN setting…

    Scene Modes


    Scene Modes

    Let your camera make the decisions!

    Lady = Portraits

    Mountains = Landscapes

    Flower = Macro Photos

    Runner = Action Photos

    Star – Night time Photos

    Others: “Food”, “Candlelight”, “Fireworks, “Snow”, “NightShot”, “Performance”, etc…


    Scene Modes

    M = Manual Mode

    AV = Aperture Priority

    TV = Shutter Priority (Canon)

    S = Shutter Priority (Nikon)

    P – Evil, evil Program Mode


    Scene Modes

    Aperture Priority – You set the Aperture and the camera selects

    the ISO Sensitivity and Shutter Speeds for proper exposure

    Shutter Priority – You set the Shutter Speed and the camera selects

    the ISO Sensitivity and Aperturefor proper exposure
