Photographers normally use a tripod (three-legged stand) to hold a camera steady.
A tripod is a three legged stand, usually made to be broken down simply or carried to a different location. It is used as a base to position a camera, telescope or even an easel. A drawing would show a three legged stand, each leg pointing out.
A camera stand with two legs is commonly referred to as a "tripod." However, technically, a tripod has three legs; a two-legged camera support is typically called a "monopod." Monopods provide stability and support while allowing for greater mobility and are often used by photographers and videographers for easier handling.
