Shutter speed

...

“Runners coming!”

“Quick, shoot them!”

“Aw heck, they came out all blurred.”

“What can you expect shooting on 1/60 second? Try 1/6400.”

“Wow, got 'em!”

Speed mattered more in the days of film. Shoot at too fast a shutter speed and not enough light hit the film. Go from 1/125 second to 1/250 second and half as much light entered the camera. So you needed to open the aperture by an f stop, eg f4 to f5.6.

Digital cameras these days shoot fast but still retain the ability to capture light when shooting in Tv (time value mode) since the aperture is automatically adjusted.
