Shutter speed increments

“

- In the first part of this series, we went over a lot of numbers related to shutter speed and aperture. Numbers can be confusing to a lot of people, but I hope you weren't overwhelmed, because the exposure calculations that we've been talking about are really very simple when you remember that a stop is a doubling or halving of light. So when you see shutter speeds listed as 1/250, 1/500, 1/1000, 1/2000, when you recognize those as doublings, it becomes pretty easy to realize that going from 1/250 to 1/500 means cutting the amount of light in your exposure in half. Now there's one odd shutter speed in the whole stop shutter speed list. Here are the traditional whole stop shutter speeds. 1/60, 1/125, 1/250, 1/500, 1/1000, 1/2000. That jump in there from 1/60 to 1/125. That's the only one in the list that's not a perfect doubling. Doubling 1/60 should result in 1/120, so is there some significance to 1/125 of a second? Some reason it's not a perfect doubling? No. For all practical…
