Document Summary

Amount of light falling on digital sensor to create image. Controlled by 4 factors: 1) available light, 2) iso, 3) shutter speed, 4) f-stop. Underexposed = too low iso or too high shutter or too high f stop. Overexposed = too high iso or too low shutter or too low f stop. Iso 100), less / ner grain (vice versa) Standard is iso 200, ideally shoot at lowest possible. Iso 800 or higher may begin to show grain / noise. If sunny, low; if cloudy, medium; if dark, high. Amount of time camera"s shutter is open. 1/3s vs. 1/500s) more light that is let in = brighter photo (vice versa) 1/500s or 1/1000s better for freezing fast action. Rule: shutter speed should be: 1 / lens length or if not full frame, 1 / lens length x 1. 6. Focal ration adjusted in equal steps / stops to denote amount of light being let through lens.
