Shouldn't this just be called a "long take"? It makes as much sense as the current name, except it's actually the real term and people might have picked it up before. (I certainly had, without having watched much behind the scenes stuff.)

There's an epic shot in Gone With the Wind where Scarlett is looking for a doctor to assist with the birthing of Melanie's baby, and runs out into the street. A passing soldier incredulously informs her that there are no doctors available... at which point the camera starts pulling back, to reveal that there are dead soldiers nearby. Then it pulls back, and back, and back, and you realize there are HUNDREDS of dead or dying soldiers in the streets of Atlanta, which is why there are no doctors available to help with a birth.

I'm not sure which category this shot should be placed in (the oner, epic tracking shot, long take...???)

Any ideas? I can't find it mentioned anywhere, and it's really one of the most technically impressive shots of the movie.
