So a one foot trace would mean the camera's shutter speed was 1/3000 of a second more or less or if video, 3000 frames a second. Pretty fast unless you are doing slow motion photography in a controlled environment. Why would a reporter be using such a fast shutter speed at this sort of event.SNIP...Mr. Mills was using a Sony digital camera capable of capturing images at up to 30 frames per second. He took these photos with a shutter speed of 1/8,000th of a second — extremely fast by industry standards...
...“If the gunman was firing an AR-15-style rifle, the .223-caliber or 5.56-millimeter bullets they use travel at roughly 3,200 feet per second when they leave the weapon’s muzzle,’’ Mr. Harrigan said. “And with a 1/8,000th of a second shutter speed, this would allow the bullet to travel approximately four-tenths of a foot while the shutter is open.” SNIP
Four tenths is ~ 4.8 inches. Looks longer than that in the photo.
