Photo Terms

ISO - Film speed (the measure of a photographic film's sensitivity to light) is designated by a single, almost universally-accepted common system developed by the International Organization for Standardization which uses the initials “ISO” before the film-speed number - e.g. ISO 100.

EXPOSURE VALUE - The Exposure Value (EV) system, which originated in Germany in the 1950s, was created to be a simple-to-use substitute for the shutter speed/aperture combination, using a single number instead of two.
DIAPHRAGM - A ring or plate with a hole in the center that controls the amount of light entering the camera. An adjustable diaphragm in a lens controls the size of the hole, or aperture, thereby permitting more or less light to pass through the lens to the film.
SPEED - A measure of the sensitivity to light of a photographic emulsion (combination).
DEPTH OF FIELD - The range of distance in a scene that appears to be in focus and will be reproduced as being acceptably sharp in an image. Depth of field is controlled by the lens aperture, and extends for a distance in front of and behind the point on which the lens is focused.

DEPTH OF FIELD - how much of the picture is in focus. The higher the aperture, the whole picture is in focus. The lower the aperture, the background will be blurred. If you take pictures close, you’ll have a small depth of field. If you take pictures far away, you’ll have a large depth of field. Pictures taken with telephoto lenses have a small depth of field

KELVIN DEGREES: you can change the setting based on what type of light you’re in. 5200 degrees is normal light. Tungsten light is 3200 degrees. The higher the degrees are, the bluer the picture is.
LIGHT METER: a meter in your camera that tells you the amount of light that is entering your camera. If you want your picture to be brighter, you change the light meter to + numbers. If you want your picture to be darker, you change the light meter to – numbers.

-Two different settings: one for pictures taken w/out flash, and another when using the flash
