Why is everybody so keen to have the photographer standing on the skids instead of having him/her properly attached to the existing and approved seat by the approved seat-belt?
A professional photographer combined with a professional pilot should be able to cope with the limitation in moving space.
Furthermore, keeping the camera inside the helicopter will allow for better exposure times and if it brakes it will be covered by insurance. A camera dropping from a helicopter obviously wasn't carried inside the helicopter thus is not covered by insurance
