How can themeparks snap a crystal clear picture of you on a rollercoaster going 70mph
In: Technology
To further the other comments – if the location where they choose to take the photo is lit primarily by the flash (and I’ve not seen a roller coaster photo where that is not the case) then the duration of the flash effectively becomes the shutter speed (because the image is lit by the flash – and the camera can only capture an image while the flash is “on”).
Flashes can have *extremely* short durations (1/1000 down to 1/20000 of a second) this means that they are really good at stopping motion.
