In days long gone when I shot a lot of drag racing, I frequently tried to time 
shots. I soon learned that if I saw it in the viewfinder, I didn't get it. The 
mirror, of course, has to be up at the opportune moment.

Another interesting aside: When airbags were a big deal in cars, every 
manufacturer wanted to show them opening. We shot them with a camera that did 
two thousand frames per second. That's right, 2000/second. The camera screamed 
for each three second shot. It was air cooled and powered by a ten horsepower 
motor. The "tripod" was huge. It must have weighed close to 1000 pounds and it 
was bolted to the camera on all four sides and secured to anchors embedded in 
the concrete floor of the studio. Needless to say, the film sometimes broke. 
Every time that happened it meant another $500 or so worth of film went in the 
trash can. The machine gun approach can work, but it's expensive <vbg>. Lots of 
fun.
