Photography
Depth of Field Calculator
Estimates the total depth-of-field range in millimeters from focal length, aperture, and subject distance, assuming a full-frame sensor. Use it when choosing settings for portraits, landscapes, or macro shots.

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.
