Stop motion/Talk

Changed the wording a little just because the original confused me on first reading--sounded like someone taking individual snapshots and then somehow transferring them to a strip of film. Maybe it's just me.

I put in the bit about Willis O'Brien just because I like the guy.

Not to be contentious, but your revision (while better) is still not as precise as it might be: every camera does in fact "expose single frames," but continuously, at the rate of 24 frames per second. I'd change it to "can expose a single frame at a time, at command rather than continuously," or something to that effect--but I'm not sure that that is in fact the way it works.
