I am making a crane(jib) whatever you call it and I have a concept for the crane itself but not for how I will actually move the camera. I heard wires work but I can not seem to grasp teh concept.* It is a heaver camera by the way*
On a real camera crane you would press the up and down button that moves the wrist part of it. ( I drove a forklift). If you are doing to yourself you'll have to rely on the elbow movements. I might think about renting a Genie lift. And letting someone be your hands in the thing. Unless you know how to build a fully articulating hydraulic ball-joint?
