ABSTRACT:
A camera riser has a centering ring that engages an inner surface or diameter of the raised ring on a camera head. As a result, camera riser can automatically and securely center most camera heads. This saves time in setting up the camera. Even if the castle ring holding the camera head onto the camera riser becomes loose, the camera head remains centered on the head. The centering ring may also be used to center two or more risers joined together.
