SHUTTER SPEED
The shutter blocks all light from exposing the film UNTIL you press the button. Then it quickly opens and closes, giving the film a brief flash of light.
Longer shutter speeds = more lightshorter shutter speeds = less light
APERTURE
• Before light reaches film, it must pass through an opening called an "Aperture". The aperture is like a pupil. You can control the
aperture by setting the "Aperture Opening", also known as an F-Stop
• lower numbers = slower films = need more light = longer exposures
higher numbers = faster films = need less light = shorter exposures
Wide-angle lenses allow more of a picture to be captured (need focal point) while telephoto lenses tighten the scene and isolate the subject (but affect the depth of field & increase camera shake)
