What is Aperture?
Aperture is a camera setting that's together with shutter speed and ISO. What this setting does is it allows how much light it lets in, this is important for shutter speed as it needs a fast shutter speed for most pictures.
The smaller the aperture is, the greater distance it'll focus on.
The larger the aperture is, it'll be out of focus for further objects.
