Photography
Exposure Value Calculator
Computes the Exposure Value (EV) at ISO 100 from aperture and shutter speed, giving a single number that represents the total light reaching the sensor. Use it to compare exposure settings or match lighting conditions across scenes.

Optics
Depth of Field Calculator
Compute the total depth of field for any camera and lens combination using focal length, f-number, focus distance, and circle of confusion. Use it to plan sharp focus zones before a shoot.
