Basic Exposure Controls

SHUTTER SPEEDS

APERTURE / F-STOPS

ISO SENSITIVITY


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


Iso sensitivity1

Higher the number, more grain and artifacts

ISO Sensitivity


Aperture or f stops

  • 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

    -Smaller opening for brighter situations

    (f8, f11, f16, f22)

    -Wider opening for darker situations

    (f2.8, f4. f5.6)


    Aperture or f stops2

    Aperture also determines the depth of field

    Or, what’s in focus from front to back

    Aperture orf-stops


    Shutter speeds controls how fast the shutter opens and closes

    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 speeds control how fast the shutter opens and closes

    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!

    Shutter speeds slow shutter speeds exaggerate the action

    Shutter SpeedsSlow Shutter Speeds Exaggerate the Action

    1/30th or less


    Iso shutter speed aperture balanced together determine proper exposure

    ISO + Shutter Speed + Aperturebalanced togetherdetermine proper exposure

    “Sunny 16 Rule?”


    What s proper exposure

    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

    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 modes1

    Scene Modes

    M = Manual Mode

    AV = Aperture Priority

    TV = Shutter Priority (Canon)

    S = Shutter Priority (Nikon)

    P – Evil, evil Program Mode


    Scene modes2

    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
