Whether you are working with film or digital photography, the factors in correct exposure are the same. The variables include (1) the amount of light coming from the scene being photographed, (2) the shutter speed setting, and (3) the f-stop setting, which controls the size of the aperture.
The amount of light is pretty easy to understand. On a bright sunny summer day there is an abundance of light, and at night light is minimal. Without understanding of how to set your camera for an ideal exposure, your photograph may be washed out (overexposed), or too dark (underexposed.)
I once attended a photography class by Monte Nagler in Birmingham, Michigan, at which he explained that proper exposure is like filling up a bucket of water from a faucet. Thanks for the visual explanation, Monte!
