Explain how you would set the correct ISO
ISO means: The cameras sensor`s sensitivity to light.
You should always try to shoot with the lowest ISO settings possible. This makes a photo with higher resolution, and less noise. If you are in a situation with low light you need to bring the ISO up. This adds noise, but allows you to shoot pictures in less light.
Low ISO – better image quality – needs more light – wider aperture – slower shutter speed
High ISO – more noise in the image – needs less light – smaller aperture – faster shutter speed.

Explain how you would change the aperture
The aperture is what is shown as f on your camera. The lower(smaller) the f-number the wider the opening.
A small aperture enables you to get a sharp focus point, and a shallow depth of field (blurry background).
Larger number – smaller lens opening -less light gets through – you need a slower shutter speed. If you want more depth of field you need a smaller aperture which means a higher number. (big equals more)

A big aperture enables you to get a good focus throughout the photo. This way you dont get the blurred background.
Lower number – bigger lens opening – more light gets throuh – you can use a faster shutter speed.
Explain how you would change the shutter speed
The shutter speed is the amount of time shutter is open, and allows light to pass through.
A slow shutter speed lets you get a sense og motion in the photo. (Waterfalls) This increases the depth of field.
If you want some parts of the photo to be sharp, and some to be blurry you have tho follow the object with the lense.

A fast shutter speed stop motion, and allows us to freeze the object.
