The muzzle velocity of a .223 bullet is about 1200 to 4000 feet per second depending on particulars. If the bullet whizzing past Trump hadn’t slowed much it would travel 18” on a picture taken with a shutter speed of 1/800th to 1/2600th of a second. Those are fast but not uncommon shutter speeds with modern digital cameras.
If that photo was taken at 1/8000th of a second as the graphic says, 18” of bullet travel would indicate 12,000 feet per second. 1/8000th of a second isn’t likely - .223’s don’t travel that fast. The camera didn’t have to be super special, just timely.
At 1/8000th of a second, captured only 30 times a second leaves a lot of time for a moving 2000 foot per second projectile to not be in frame.
“Mist” from the President’s nicked ear, however, might float in the bullet’s vacuum trail for an instant.
Now I want to know if it really WAS set at 1/8000th.
Remember too, that pic is the vapor trail that it momentarily created in passing.
