Hi
They used a wescam mount which is standard for areal photography but attached a 40x Canon Zoom lens with the 2x extender. I saw the film last week and was amazed how steady it was. I have used the 40x a few times and especilly with the extender on, if you just breathed at the lens it would shake. So it's really amazing footage they could get. They flew the helicopter with the wescam rig around the world to film whereever they needed it. They were shootong for 4 years! The budget by the way was 47Million? for the 13 episodes and the feature length version. So they really had the budget to do it right.
What I am interested in is how they did the timelaps of a landscape scenery where the vegetation is going through 4 seasons. They do it again and again on different locations I want to know what technique hey used. I am guessing a 35mm still camera on a rotating base plate attached to a computer or something. But I would like to know it excatly if anybody knows.
Best
