BASIC OF PHOTOGRAPHY Iso

Shutter speed

Aperture

APERTURE A device that controls the amount of light admitted through an

opening. In photography and digital photography , aperture is the unit of measurement that defines the size of the opening in the lens that can be adjusted to control the amount of light reaching the film or digital sensor. The size of the aperture is measured in F-stop

SHUTTER SPEED In photography and digital photography the shutter speed is the unit of

measurement which determines how long shutter  remains open as the picture is taken. The slower the shutter speed, the longer the exposure time. The shutter speed and aperture together control the total amount of light reaching the sensor. Shutter speeds are expressed in seconds or fractions of a second. For example 2, 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. Each speed increment halves the amount of light.

ISO International Statdred Organization lower the ISO number,

the less sensitive it is to the light, while a higher ISO number increases the sensitivity of your camera. The component within your camera that can change sensitivity is called “image sensor” or simply “sensor”
