# data[].attributes.body
Aperture priority, often abbreviated A or Av on a camera mode dial, is a setting on some cameras that allows the user to set a specific aperture value while the camera selects a shutter speed to match it that will result in proper exposure based on the lighting conditions as measured by the camera's light meter.
