Aperture

Aperture

Aperture, or f-stop, refers to how big the hole will be for the light to pass through when the shutter is open and the picture is snapped.

Lower f numbers correspond with larger holes.

The important thing to remember is this: the higher the f number, the more things in front of and behind the subject will be in focus, but the more light you will need.

The lower the f number, the more things in front of and behind the subject will be out of focus, and the less light you will need.
