Exposure Triangle
The three main elements that include the Exposure Triangle would be Shutter speed, Aperture, and ISO.
Shutter speed
determines how long the shutter stays open as the picture is taken. Shutter speeds are in seconds or fractions of a second. Each speed number halves the amount of light of2, 1, 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125, 1/250, 1/500, 1/1000, 1/2000, 1/4000, 1/8000 .
Aperture
an open, hole, or a gap.
A space thru which light passes throught that one spot.
ISO
photographs is the sensitivity of your image senor or film inside your camera. This measure of sensitivity is expressed as ISO speed and it's kind of a big deal when your light is less than ideal.
