Inertial augmentation and balance
An operator can arrange the major components of the Steadicam to change the sled's inertial character. Expanding the sled increases angular inertia, and compressing the sled reduces angular inertia.
Moving the components around gives the rig a different feel — from slow and elegant to quick and light — similar to handheld shooting.
The most useful technique to change the sled's angular inertia is to extend or compress the central post and/or to place the monitor and battery closer or farther from the central post.
The other technique is to add mass to the sled. Heavy cameras and monitors make for slower and more ...
