By comparison, the house implosion at the end of "Poltergeist" was shot at 300fps.

I read somewhere that Dolby's "Rain" trailer is composed of actual slo-mo shots of water droplets colliding. I wonder what the frame rate was for that.

One of the pioneers of instrumentation photography was Harold "Doc" Edgerton of MIT, who literally invented the strobe:

This doesn't account for "wastage" involved in "running up" the camera and the film that gets destroyed at the end when the camera "tails-out". If you figure 25% waste (a wild guess) that would leave only 3 seconds of usable film. How do they really account for this? Do they splice in a length of "trash leader" at the beginning and end of the reel? OR do they just go with the waste factor in the camera and deal with it later?

I would imagine that if somebody wanted to film, say, an explosion and then play it back in somewhat of a normal pace they would have to do some sort of skip-frame editing/printing in order to "recompress" the film speed back to some semblance of normal speed.

Either that or the film would have to be played back at a different speed, based on the time expansion factor that you wanted to portray. What projector can run that fast? I know that projectors in studios and editing facilities can play back at fractional/multiple speeds but a expansion factor of 100 times would be BRUITAL... Let alone 300!

That shit is CRAZY FAST!

No??
