Underwater Depth of Field Simulator

Visualize in real-time the depth of field of your underwater photo setup. Adjust focal length, aperture, sensor, and subject distance to optimize your settings before diving.

Underwater, the refractive index of water (1.33) narrows your field of view and magnifies subjects by approximately 33 percent behind a flat port. Depth of field shrinks accordingly. This simulator computes exact optical hyperfocal distances and depth of field based on your focal length, aperture, subject distance, and sensor format.
