aperture can be looked at as the almost ‘pupil’ of the camera: it sets the amount of light able to go into the camera.
the maximum the fstop in the aperture, the more light let in, like an f/1.2, and the minimum fstop, such as f/22, the least amount of light let into the camera and photograph.
also, the larger (actually speaking, ‘smaller’) the aperture, the blurrier the background is.
the aperture size of f/6.3 isn’t all that large, so it wouldn’t be that great for indoor photography, unless you’ve got some wicked strobes.
