Steadicam is a brand of camera stabilizer mounts for movie cameras invented by Garrett Brown, introduced in 1975 by Tiffen. It mechanically isolates the operator's movement, allowing for a smooth shot, even when moving over any surface.
Before the camera stabilizing system, a director had two choices for moving (or "tracking") shots:
- The camera could be mounted on a camera dolly, a wheeled mount that rolls on tracks or leveled boards. This is time consuming to set up, and depending on the location, impractical in many situations.
- The camera operator could hold the camera in his hands. This allows greater speed and flexibility, but even the most skilled operator cannot entirely prevent shaking. Hand-held camera footage has traditionally been considered suitable mostly for documentaries, news, reportage work, live action, unrehearsable footage, or to evoke an atmosphere of authentic immediacy or cinéma vérité during dramatic sequences.
A Steadicam essentially combines the stabilized steady footage of a conventional tripod mount with the fluid motion of a dolly shot and the flexibility of hand-held camera work. While smoothly following the operator's broad movements, the Steadicam's armature absorbs jerks, bumps, and shakes.
The Steadicam was introduced to the industry in 1975 by inventor and cameraman Garrett Brown, who originally named the invention the "Brown Stabilizer". After completing the first working prototype, Brown shot a ten-minute demo reel of the revolutionary moves this new device could produce. This reel was seen by numerous directors, including Stanley Kubrick and John G. Avildsen. The Steadicam was subsequently licensed to and manufactured by Cinema Products Corporation, which later diversified the brand into a consumer line for DV cameras.
The Steadicam was first used in the Best Picture–nominated Woody Guthrie biopic Bound for Glory (1976), debuting with a shot that compounded the Steadicam's innovation: cinematographer Haskell Wexler had Brown start the shot on a fully elevated platform crane which jibbed down, and when it reached the ground, Brown stepped off and walked the camera through the set. This technically audacious and previously impossible shot created considerable interest in how it had been accomplished, and impressed the Academy enough for Wexler to win the Oscar for Best Cinematography that year.
It was then used in extensive running and chase scenes on the streets of New York City in Marathon Man (1976), which was actually released two months before Bound for Glory. It landed a notable third credit in Avildsen's Best Picture–winning Rocky in 1976, where it was an integral part of the film's Philadelphia street jogging/training sequences and the run up the Art Museum's flight of stairs, as well as the fight scenes where it can even be plainly seen in operation at the ringside during some wide shots of the final fight. Rocky was also released before Bound For Glory. Garrett Brown was the Steadicam operator on all of these.
The Shining (1980) pushed Brown's innovations even further, when director Stanley Kubrick requested that the camera shoot from barely above the floor. This prompted the innovation of a "low mode" bracket to mount the top of a camera to the bottom of an inverted post, which substantially increased the creative angles of the system, which previously could not go much lower than the operator's waist height. This low-mode concept remains the most important extension to the system since its inception.
A Steadicam rig was also employed during the filming of Return of the Jedi (1983), in conjunction with two gyroscopes for extra stabilization, to film the background plates for the speeder bike chase. Brown, who personally operated the shot, walked through a redwood forest, with the camera running at a speed of less than one frame per second. The end result, when projected at 24 frames per second, gave the impression of flying through the air at perilous speeds. In the Michael Crichton film Runaway (1984), a Steadicam rig was used to simulate the point of view of a futuristic smart bullet in flight while targeting specific individuals by their heat signature.
The operator wears a harness—the Steadicam vest—which is attached to an iso-elastic arm. This is connected by a multiaxis and ultra-low friction gimbal to the Steadicam armature which has the camera mounted at one end and a counterbalance weight at the other. The counterbalance usually includes the battery pack and a monitor. The monitor substitutes for the camera's viewfinder, since the range of motion of the camera relative to the operator makes the camera's own viewfinder unusable. In the film industry the armature and weight are traditionally called the sled, as they resembled a sled in an early model of the Steadicam. The sled includes the top stage where the camera is attached, the post which in most models can be extended, with the monitor and batteries at the bottom to counterbalance the camera weight. This is how the Steadicam stays upright, by simply making the bottom slightly heavier than the top, pivoting at the gimbal. This leaves the center of gravity of the whole rig, however heavy it may be, exactly at the operator's fingertip, allowing deft and finite control of the whole system with the lightest of touches on the gimbal. The skill of the operator is to keep the desired framing and composition by feathering his touch on the gimbal, while the rig and operator is in motion, and, indeed, when still.
The combined weight of the counterbalance and camera means that the armature bears a relatively high inertial mass which is not easily moved by small body movements from the operator (much as it is difficult to quickly shake a bowling ball). The freely pivoting armature adds additional stabilization to the photographed image, and makes the weight of the camera-sled assembly acceptable by allowing the body harness to support it.
When the armature is correctly adjusted, the operator is able to remove their hands from the Steadicam entirely and have the camera stay in place. During operation, the operator usually rests their hand on the camera gimbal and applies force at that point to move the camera. To avoid shaking the camera when lens adjustments must be made during the shot, a wireless remote operated by the camera assistant is used to control focus and iris.
For low-angle shots, the camera/sled armature can be rotated vertically, putting the camera on the bottom, and the sled on the top. This is referred to as low mode operation.
The newest generation is the Tango. The most modern body-supported camera-stabilization-system, its horizontal mechanism makes it possible to move the camera freely while staying horizontal. A Steadicam operator can change from low mode to high mode without any alteration. Dimensions are not limited to ups and downs, but also in depth and over or through obstacles.
The smallest, lightest Steadicam which can be used with a support arm and vest is the Merlin. It is light enough to be hand held with cameras weighing up to about 5.5 pounds (2.5 kg), and may carry cameras up to about 7 pounds (3.2 kg) when used with the arm. The Merlin may be folded up and carried in comparatively small spaces such as medium-size camera bags. In its lightest configuration, the Merlin weighs just 12.5 ounces (0.35 kg). Photographers who shoot with HDSLR cameras that combine still and motion photography most often work with the Merlin. Since the Merlin has no facility to carry a separate monitor, cameras suitable for it must have their own built-in monitors.
A smaller, lighter model was introduced in 2012, called the Smoothee. Its tubular frame can support Apple iPhones (4 through 5S) along with GoPro cameras that have the attached viewfinder monitor. Its target retail price was originally "under $200" and it may be purchased in consumer stores. Pre-weighted, balanced iPhone and GoPro adapters modularly allow interchange of cameras. An even smaller, camera-specific Steadicam Curve is available for the GoPro cameras (2, 3 and 3+) which is made of a single, curved slash of aluminum. Its target retail price is just $100, and it, too, is available in consumer outlets.
