Aperture

The setting on a camera's lens which controls how much light comes into the camera. Aperture settings can usually be set to F-stop values ranging from F1.4-F22. The higher the aperture value, the smaller the opening is, and vice versa, which affects the depth of field in photos and how much light reaches and illuminates a subject or scene in a photo.
