A tripod is a three-legged support structure used to stabilize a camera or other device. It is used to prevent camera shake and achieve sharp images, especially in low-light conditions or when using a telephoto lens.
Tripods come in a variety of shapes and sizes, and can be made of different materials such as aluminum, carbon fiber, or wood. They typically have adjustable legs that allow them to be set up on uneven surfaces, and some models also feature a center column that can be extended to increase the height of the tripod.
