Measured in f-stops such as f/1.8, f/4, or f/16, aperture determines both exposure and focus characteristics. A wide aperture (low f-number) lets in more light and produces a shallow depth of field, creating background blur and subject separation. A narrow aperture (high f-number) allows less light but keeps more of the scene in focus. Aperture also influences lens sharpness, diffraction, and overall image character. Cinematographers adjust aperture not only for brightness but also to control visual storytelling, isolating subjects or revealing environments. Because aperture affects both exposure and aesthetic style, it is one of the most creatively powerful camera settings.
