Ever need to get your camera lower then what you can get with a tripod? Of just don't have an extra hand to hold the camera? Here is a handy item to solve your problems and a few sample pics.
It can be used to as a ground plate and the camera angle is adjustable by rotating the camera on the mounting screw. The ground is seldom level but if it is I just put a rock or something under one side to level it up.
For hands free camera use just mount the camera on the edge and add a neck strap and bungee to hold it firmly in place.
