What does isolation of the camera accomplish? Most hand-held shots suffer from a distinct jerkiness. This is because the camera is subject to all of the movements of the operator -- including the undesired shocks and bounces that accompany each footstep. In the human body, the muscles, joints, tendons and ligaments absorb a large portion of these shocks; what the body does not absorb, the muscles of the eyes and the image processing of the brain corrects for, turning a bumpy ride into a smooth flight. . These undesired shocks of walking consist of two elements: 1) quick movement of the entire camera by a small amount, and 2) rotation of the camera itself (tilt, pan, and roll). Successful isolation will significantly reduce the size of both types of movement -- and the Steadicam is designed and manufactured for successful isolation. Isolation from whole-camera movement This is the work of the **Articulated Arm**. The articulating arm absorbs the up-and-down movements of the operator, taking advantage of the mass of the camera, as well as the mass of the **sled**, **post** and **gimbal** parts of the Steadicam. What is Steadicam well suited for? Moving camera shots in tight quarters. [Where a dolly would bang into walls, door jambs, or trees] Shots over rough ground, particularly where one needs to look straight ahead or behind. Where one needs to continue on beyond the practical distance that can be accommodated with track. Where any other technique for moving the camera would be impractical for external reasons, such as the load-bearing abilities of the floor or the rigidity of a dock or bridge, etc. for any moving camera shot where the quality of the move contributes to the emotional qualities of the scene, such as the "hardness" of accelerations/decelerations, pans, etc., and the momentary control over the balanced/unbalanced nature of the composition as actors enter or are let out of the frame.
