What is Aperture?

Aperture is ‘the size of the opening in the lens when a picture is taken. When you hit the shutter release button of your camera a hole opens up that allows your cameras image sensor to catch a glimpse of the scene you’re wanting to capture.

The aperture size that you choose, impacts the size of that hole. The larger the hole the more light that gets in – the smaller the hole the less light.

Aperture is measured in ‘f-stops’. You’ll often see them referred f/2.8, f/4, f/5.6,f/8,f/22 etc. Moving from one f-stop to the next doubles the size of the iris opening in your lens (and the amount of light getting through).

What Is Depth of Field

- Low aperture setting or F Stop, creates more ashallow depth of field, which makes it ideal for shooting portraits or when you are trying to isolate a subject.

- If you would like the image to be in focus in it's entirety, such as photographing landscapes, you need to choose a smaller aperture, which creates a deep depth of field where everything in the shot is in focus.
