1/16,000th sec? What for?

Ever see a pic of a plane as it breaks the sound barrier?

Yes, it's one of my rotating desktop pix:

Hi, 1/16,000 is not necessarily a shutter speed that you might use but it may be a shutter speed you need to attain a certain exposure at a given aperture. For instance it is not unusual to have a shutter speed of 1/60th at F22 at ISO100 on a bright day but if for a shot you wanted to use your lens at its max say f1.4 then the shutter speed for the same exposure would be 1/16000. Even more difficult on some Nikons which have a low ISO of 200. Hope this helps, Chris.

That makes sense. Thanks, Chris.

Nope. Not 1/10,000,000th (of a sec) exposure.
The rapatronic camera has "an exposure time of as little as ten nanoseconds". That is 10 x 1,000,000th of a sec = 1/100,000th of a sec.

My apologies - I misread it and was reading how long after the blast the photo was taken.

No apologies are in order here.
It's pretty quick in any math!
