Can someone explain why the falling snow in this photo looks like dashed lines instead of continuous lines? I like the photo but this artifact spoils it. I would have thought falling snowflakes would look like longer lines than this- not frame to frame of course, but the dashes just don't look right.
It was taken with a Panasonic GX7 and Olympus M 12-40 zoom. No flash, ISO 3200, 1/20 sec, f2.8, and +1/3 EV exposure compensation, using mechanical shutter, not electronic shutter. The only significant thing in post was to soften the glare from lights, but in any case that didn't make any difference to the appearance of the snow, either in the raw or as an exported jpg. The temperature would have been below zero (celsius) but not by much so I doubt that had anything to do with it.
Thanks!
John.
