Aperture and Aperture Priority

In the context of photography, the term "aperture" refers to the opening of the lens through which light passes. It is represented by an f-number or f-stop value, such as f/2.8, f/4, f/5.6, and so on. The aperture controls two main aspects of an image: the amount of light that enters the camera and the depth of field.

Aperture settings are typically adjusted using the camera's manual or semi-manual shooting modes. Here are some common aperture settings:

Wide Aperture (Low f-number, e.g., f/1.8, f/2.8): Selecting a wide aperture allows more light to enter the camera, resulting in a brighter exposure. Wide apertures are commonly used in low-light situations or when you want to create a shallow depth of field, with a blurred background and a sharp subject in focus.
