Photography
Magnification Ratio Calculator
Calculate the magnification ratio of a lens at a given subject distance β the ratio of subject image size on the sensor to actual subject size. Use it for macro photography planning to predict how large your subject will render and to choose between dedicated macro lenses, extension tubes, or close-up filters.

Photography
Hyperfocal Distance Calculator
Finds the closest focus distance at which a lens keeps everything from half that distance to infinity acceptably sharp. Essential for landscape and street photographers seeking maximum front-to-back sharpness.
