Wasn't aware of any new principles of high speed photography in the last thirty years. My point was that there's no reason to say that a measurement using high speed photography, with the big proviso that the test was properly set up, wouldn't be at least as accurate as a measurement by some guy with a hand held radar gun.marc71178 said:Because technology has moved on a tad since that day?
By properly set up, I mean that the camera is correctly positioned, it is being done with clear reference points to allow you to accurately measure the distance the ball has travelled from frame to frame, and you are using equipment where the time interval from frame to frame can be reliably calibrated. That would give you a distance/time measurement that would produce a highly accurate speed reading.
The radar gun is probably as effective, and certainly more flexible, but not necessarily more accurate.
