What is Gimbal? How does it Work?

Gimbals have revolutionized the world of photography and videography, allowing for smooth and stabilized footage even in the most challenging conditions. Whether you’re a professional filmmaker or an amateur enthusiast, understanding what a gimbal is and how it works is essential.

In this article, we will delve into the world of gimbals, exploring their functionality, applications, and benefits.

What is Gimbal?

A gimbal is a revolutionary device that enables you to capture stabilized, smooth footage from your camera while in motion. The two most common types of stabilization are 3-axis and 2-axis. 3-axis stabilizers counteract all three motions: up/down (yaw), left/right (pitch), and forwards/backwards (roll), making them the preferred choice for professionals aiming to eliminate camera shake.

2-axis stabilizers, on the other hand, only compensate for vertical motion, suitable when panning or tilting movements on a tripod are not involved.

How Does a Gimbal Work?

Gimbals work on the principle of maintaining the camera’s orientation in space, regardless of the movement of the operator or the mounting platform. They achieve this through the use of sophisticated sensors and motors. The sensors, such as gyroscopes and accelerometers, detect the camera’s movement in real-time. The motors then make precise adjustments to counteract those movements and keep the camera steady.

The three axes of rotation in a gimbal system are:

  1. Pan: This axis allows the camera to rotate horizontally from left to right or vice versa. It enables capturing sweeping panoramic shots.
  2. Tilt: The tilt axis allows the camera to move up and down. It enables vertical movements and smooth tracking shots.
  3. Roll: The roll axis allows the camera to rotate from side to side. It helps in keeping the camera level even when the mounting platform tilts or rolls.

By actively stabilizing the camera on all three axes, gimbals ensure that the footage remains smooth and steady, eliminating the effects of hand movements or vibrations.

How to Set Up a Gimbal?

Gimbals are versatile, and compatible with DSLR cameras, mirrorless cameras, smartphones, and GoPros. Here’s a step-by-step guide to setting up your gimbal:

  1. Camera Ready:
    • Ensure your camera is ready for the shoot, with correct settings and a fully charged battery.
  2. Camera Setup:
    • Mount your camera securely on the base plate, ensuring it is tightly fastened and aligned correctly.
  3. Calibration:
    • Calibrate the weight distribution, adjusting pitch arms for a 3-axis gimbal to ensure perfect balance.
  4. Activate Functions:
    • Follow the gimbal’s instructions to activate specific functions, such as Yaw Follows for dynamic tracking shots.

Gimbal vs. Steadicam

While Hollywood often uses Steadicams for smooth footage, gimbals have become the go-to for budget-conscious filmmakers. Steadicams are more complex and expensive, tailored to the specific needs of large-scale productions. However, the technology behind gimbals draws inspiration from Steadicams, making them an ideal choice for aspiring cinematographers.

2-axis Gimbals vs. 3-axis Gimbals

Understanding the difference between 2-axis and 3-axis gimbals is crucial. While 3-axis gimbals offer superior stability by stabilizing tilt, pan, and roll axes, 2-axis gimbals are lighter and consume less battery power. Your choice depends on your specific needs, goals, and budget.
