Joseph Francis's Comments

It's actually pretty cool right on Google Earth. You can sort of descend into the cone, and when you are done with that you can take a virtual tour of the 3D-modeled Pompeii ruins.

The image is transmitted to the screen by means of a rotating prism, so the film never stops, it just rolls past a hunk of specially shaped glass. This is how very high speed film cameras also work, as I understand it.

In a moviola the film stops intermittently in the gate, where it is held still for a beat. The spool out and uptake reels never stop, but loops of slack on either side of the gate back the intermittent motion within the gate possible. I high speed camera couldn't operate in this way, it would be too stressful on the film.
