Shutter Speed

• Definition: Shutter speed is the amount of time that light is able to shine through the inside of the camera lens.

• When you change the shutter speed, depending on the setting the digital sensor is exposed to light in different amounts of time. With a slower shutter speed, you get more motion blurs in the photo, but with a faster shutter speed, you get freeze action with no blurs at all.

• In order to balance out the light meter when doing shutter speed, the aperture needs to be changed and ISO should be changed only when needed. For a faster shutter speed, you need to have a lower f-stop, for a slower shutter speed, you need to have a higher f-stop. 

Aperture

• Definition: Aperture is the amount of light that is able to shine through the inside of the camera lens. The amount light that shines through variates depending on what settings we use.

• When you change the aperture, the size of the opening of the lens changes depending on the setting. With a lower f-stop you get a very shallow depth of field (blur), but with a higher f-stop, you get a larger depth of field (clear).

• In order to balance out the light meter when doing aperture, the shutter speed needs to be changed and ISO needs to stay constant. For a lower f-stop, you need to have a faster shutter speed, and for a higher f-stop, you need to have a slower shutter speed.
