Camera Iris Diagram - Understanding Aperture Mechanics in Photography #1630486 (License: Personal Use)

This black-and-white schematic depicts a classic six-blade camera iris diaphragm, where overlapping blades pivot to widen or narrow the central aperture. The design illustrates the mechanical principle behind exposure control in lenses-allowing precise regulation of light entering the sensor or film plane. Such diagrams are widely used in optics education and camera manuals.

Used on photography tutorial pages, optics educational sites, or camera repair guides; serves users seeking to understand aperture mechanics, lens design, or exposure fundamentals.
