One thing I've always wondered about the landings is why the camera zooms out and tilts up as the lunar lander blasts off from the moon. Seeing how there wasn't a cameraguy to follow the rise of the craft, how did it do it?
For Apollo 15, 16 and 17 the camera was on the Lunar Rover. With 15 the camera was carried on the MESA like the eariler missions and then taken from that and placed on a tripod before being transfered to the Rover, for 16 and 17 the camera was on the Rover from the start.
The TV camera mount had the ability to rotate 360° and tilt up and down, all under the control of a guy named Ed Fendell. He was seated in Houston and his whole job was to control the camera so that the Geologists could ask to see various things (it gets really tedious when the camera keeps pointing at rocks when you'd rather be watching the crew let me tell you.)
The idea behind the lift off was that the LRV was parked a certain distance from the LM and that about 1.5 seconds before the lift off, Ed would start the camera up and along a predetermined path at a predetermined rate. This had in fact been practiced a number of times so tbhat he would get it right. However, as with all things, just because it was well practiced doesn't mean that it worked out.
On Apollo 15 the camera was damaged and they weren't able to pan the camera up to follow the take off. On Apollo 16 the crew accidently parked the LRV too close to the LM and while the take off was filmed, the LM's ascent module quickly heads out of sight through the top of the frame. Finally on the last attempt, Apollo 17, everything worked as planned, and they got good footage of the LM taking off. So it only took them three tries, but they got it.
Apollo 11 does have a lift off film, but this, like the landing film, was taken with the DAC which was set into a bracket over the LMP's window.
Hope that helps.
