what is aperture in camera
Aperture is an opening within the lens of a camera that limits the amount of light that enters the camera to make an exposure, it can be adjusted so as to change the depth-of-field. The size of this opening can be expressed in various ways such as f-stop or T-stop. It is one of three photographic components (along with shutter speed and ISO) that affect exposure. The other two components are generally referred to as the "exposure triangle". The size of aperture affects not just the amount of light entering the camera , but also how much the lens acts to shape that light, since a small aperture produces a wide depth-of-field (DOF), and a large aperture makes the subject very sharp and in focus.

It is equal to f/2.8 or f/32 where "f" stands for focal length and "n" stands for one over that number. In 3
