f stop
Aperture ratio setting
An f-stop is a camera setting that controls how much light enters through the lens, expressed as a ratio of focal length to aperture diameter: f/2.8, f/8, f/16.
Lower numbers mean wider openings and more light; higher numbers mean narrower openings and greater depth of field.
She opened up to f/1.4 for the low-light shot.
