Understanding Camera Aperture: f/2.8 to f/11 Visual Guide #3260623 (License: Personal Use)

This diagram displays four standard aperture values-f/2.8, f/5.6, f/8, and f/11-with corresponding iris shapes showing how the opening narrows as the f-number increases. Each representation uses a classic multi-blade diaphragm design typical of DSLR and mirrorless lenses. The progression visually demonstrates the trade-off between light intake and depth of field in photographic exposure.

Used in photography tutorials, camera manuals, or beginner guides to explain exposure triangle concepts; matches user intent to understand how f-stops affect image brightness and focus range.
