LECTURE : 

Exposure : Shutter speed, Aperture and ISO.
is the act of exposing the image sensor to light. By adjusting the amount of light, you can make a photograph of a bright sunlit scene look dark, or a shot of a dark interior look bright.

Shutter speed is a measurement of the time the shutter is open, shown in seconds or fractions of a second: 1 s, 1/2 s, 1/4 s … 1/250 s, 1/ 500 s, etc. The shorter the time the image sensor is exposed to light, the darker the resulting photograph.

Aperture (expressed as an f-number) controls the brightness of the image that passes through the lens and falls on the image sensor. The higher the f-number, the darker the image projected on the image sensor.

ISO is a camera setting that increases or lowers the amount of light in a photograph. It’s always best to take advantage of all the natural light you can get your lens on, but sometimes darker conditions call for a higher ISO.
