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!

ISO + Shutter Speed + Aperturebalanced togetherdetermine proper exposure “Sunny 16 Rule?”
How will I know I have reached exposure Nirvana? What’s Proper Exposure?
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
