๐ท Shutter Speed Calculator
B is the slower (brighter) shutter speed
* Enter a fraction like "1/125", or a number of seconds like "2" or "0.5".
Enter two shutter speeds โ as a fraction like "1/125" or a number of seconds โ and see the difference between them in stops (EV). Useful for adjusting exposure compensation or manual camera settings, so you know exactly how much brighter or darker a change will make your shot.
How to use
- Enter the two shutter speeds you want to compare, as a fraction like "1/125" or a number of seconds like "2".
- The equivalent value in milliseconds for each, and the stop (EV) difference between them, are shown automatically.
FAQ
What does "stops (EV)" mean?
A stop (or EV, exposure value) is a photography unit where 1 stop means doubling or halving the amount of light. Slowing the shutter speed by 1 stop lets in twice as much light.
Does this support formats other than "1/125"?
Yes โ besides fraction notation like "1/125", you can also enter a number of seconds like "2" or "0.5" (decimals allowed).
Can this calculate stops for aperture (f-stop) or ISO too?
No โ this tool is dedicated to calculating the stop difference between shutter speeds only.
