Shutter speed

The shutter speed is the amount of time that the shutter is open or is the length of time that the image sensor sees the scene.

The shutter speed is measured in seconds.

Fast shutter speed

Is used to freeze a movement. We can see the drops of water freeze.

Slow shutter speed

Is used to make a movement blur. We can observe a foot blur, when someone is running.

ISO

ISO is the International Organization for Standardization.

It’s the camera’s sensitivity.

There are high ISO and low ISO.

High ISO

With a high ISO, 1600 in our case, the photo less illuminated because of the sensitivity of the camera. The photo is less clear.

Low ISO

With a lower ISO, 100 in our case, the photo is more illuminated because of the sensitivity of the camera. The photo is more clear.

Aperture

The aperture is the size of the opening in the lens when a picture is taken.

There are large and small aperture.

Large aperture

When we use a large aperture more light gets in and the background gets blur. On the other hand, the foreground is focus.

Small aperture

We have used a small aperture to focus all the things of the picture.
