How to Mount a Quick Release to Camera Rig

The Giottos M621 Quick release provides a solid, adjustable attachment of the camera. It even has bubble levels. Compared to the Manfrotto quick release, The Giottos works better with DSLRs because the sliding plate is centered with the base. The Manfrotto has a ~5mm offset, which I believe is designed to work with video cameras. The Canon video camera that I use has the tripod mount screw offset from the center of the lens.
