Not sure, but I think I've heard somewhere that some cameras are set to take several pictures AFTER the button is pressed to help account for things like shut eyes or to help capture better moments than in initial button press?
Yes. That is certainly a thing you can do. It's called Burst mode. But it suffers the same framerate problem as a regular continuous camera. Most Burst modes are in the 10 fps range or so. Some go as high as 60 fps. I don't think there are any "high speed" burst mode cameras, because that would be kinda pointless. You want a lower framerate because reality doesn't usually move fast enough to get a meaningfully different picture 1/10,000th of a second later.
Unless of course, you are trying to take a picture of a bullet, in which case you would just use a regular high speed camera, or fake the picture.
