EV setting: denotes all combinations of a camera's shutter speed and relative aperture
Diaphragm: a thin opaque structure with an opening (aperture) at its center, objective is to stop the passage of light, except for the light passing through the aperture
Speed setting: common term used to discuss exposure time, the effective length of time a camera's shutter is open, The total exposure is proportional to this exposure time, or duration of light reaching the film or image sensor.
Depth of Field: the portion of a scene that appears acceptably sharp in the image
Aperture: the aperture of an optical system is the opening that determines the cone angle of a bundle of rays of light that come to a focus in the image plane
Kelvin degrees: measure of the temperature of color. A flash is- 5500 degrees. You can change the Kelvin degrees on your camera to show different types of light that you wish to see
Sensor: The type of device used in digital camera and camcorders to capture an image. The 2 most common types are known as CCD (charge-coupled device) and CMOS (complementary metal oxide semiconductor)
