Both calculators run independently β change the inputs on either side to compare results.
Exposure Equivalents Calculator
Find equivalent camera settings that produce the same exposure value when you change aperture, shutter speed, or ISO. Useful any time you want to swap depth-of-field or motion blur without altering overall image brightness.
Equivalent Shutter Speed
0.4 s
At 0.1 s and longer, motion blur is unavoidable handheld. Use a tripod and remote release; subjects moving during a 0.4 s exposure will streak.
The equivalent shutter speed comes from the reciprocity formula; these bands reflect the photographic rule that handholding usually requires faster than about 1/60 s (0.0167 s).
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.
