A small camera sensor on the left hand side of the camera's body is set up to capture the videographer's hand as he/she cranks an imaginary arm. Simulating the first film cameras, the crank speed would regulate how fast the picture is captured. Crank slowly and you get fast-motion pictures. Crank quickly and you can get slow-mo. Simple motion tracking and a wide-angle lens is all that is required. A display on the LCD screen would show you how over/under your speed is. Software control would also allow for freewheeling and speed regulation to make changes in speed smooth. For those who don't understand the physics of film cameras, a reverse speed mode would allow you to crank slowly for slow mo and fast for fast motion capture.-- Cedar Park, Mar 28 2012 You mean like this? http://www.youtube....watch?v=ZeUfvrPlVGIHand Cranking an Arri D-20 [ytk, Mar 28 2012] The camera should be concealed in the supporting hand.-- pocmloc, Mar 28 2012 Why can't the camera have a real crank?-- hippo, Mar 28 2012 Sounds like a wind-up to us.-- 8th of 7, Mar 28 2012 [hippo] because there's no room with the LCD screen sticking out on modern digicams. //brainstorm// The camera sensor might be located on the end of the LCD screen.-- Cedar Park, Mar 29 2012 random, halfbakery
