Aperturelab is a photographer's pocket workbench. Work out depth of field and the hyperfocal distance from your focal length, aperture and subject distance, solve the exposure triangle to keep your exposure constant when you change one setting, run a long-exposure timer with reciprocity, and keep a log of your favourite shots and settings. Fully offline, no accounts, no ads.
