2. 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.

3. Fast shutter speed
Is used to freeze a movement.
We can see the drops of water freeze.

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

5. ISO
 ISO is the International Organization for
Standardization.
 It’s the camera’s sensitivity.
 There are high ISO and low ISO.

6. 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.

7. 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.

8. Aperture
 The aperture is the size of the opening in the
lens when a picture is taken.
 There are large and small aperture.

9. 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.

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