  SHUTTER, APERTURE AND ISO BASIC

  In relation to light, what does the shutter speed determine?

- The shutter speed determines the amount of light that hits the image sensor.

  What is the shutter speed general used to control?

- It is used to control the movement.

  What effects can different shutter speeds create?

- It can be used to freeze motion or blur images.

  Explain the difference between large and small aperture.

- The larger the opening on the aperture the more light that hits the image senor. This means that the smaller the opening on the aperture the less light that will hit the image senor.

  What is depth of Field?

- This means how much of the image is in focus.

  What affects does a small aperture and a large aperture have?

- The smaller the aperture the more detailed the photo will be. The larger the aperture the less in focus to photo will be.

  Explain the relationship between ISO and light sensitivity.

-          The ISO determines how sensitive the light sensor is
What is ‘noise’ grain?

-          If there is noise grain on the photo this means that the image looks grainy

 Explain what‘each element does not work in isolation‘ mean?

-          This means that the ISO, aperture and shutter speed need to work together.

Explain the Exposure Triangle.

-          Low shutter speed + small aperture = correct exposure

-          Fast shutter speed + large aperture = correct exposure
