Concepts in Photography

Shutter speed

Shutter speed refers to the amount of time it takes to open and close

the shutter, and it is an important factor in the brightness of a photo, as

it controls the amount of light which passes through the aperture before

it reaches the image sensor.

Usually, the shutter speed is manually adjustable. The measurement

of the shutter speed is known as the “Exposure Value” (EV), which is

marked in intervals of 1 s, 1/2 s, 1/4 s, 1/8 s, 1/15 s, 1/1000 s, 1/2000

s, and so on.

Shutter Speed

The numbers indicated on the camera are the denominators of

exposure values, which means that the higher the number, the less light

will be let in. Likewise, the smaller the EV number, the more light will be

let in.

As the photos below illustrate, a slow shutter speed allows more time

to let light in, so the photo becomes brighter. On the other hand, a fast

shutter speed allows less time to let light in and the photo becomes

darker and more easily freezes subjects in motion.
