Ball heads provide stability and mobility for photographers on the go. Combined with a stable tripod a solid ball head can help dampen out vibration for sharper photographs, especially for larger enlargements. Sharper photographs and videos make for smaller, higher quality multimedia for the Web.
A ball head sits atop a tripod to provide support for cameras and camcorders. Ball heads provide more flexibility than 3-axis "pan-tilt" heads, they're faster to use and lighter in weight. Aiming and leveling can be done in one fluid motion, a feat that would take multiple steps with a pan-tilt head.
Ball heads come in different shapes and sizes designed to support different types of cameras. Like tripods they are rated by the amount of weight that they can support. The features to look for are ball diameter, multiple secure contact points to the ball, variable tension control, height, and rated support weight. The larger the ball and the more secure the mechanism, the more solid the ball head.
