Cost-effective camera stabilizer selection guide
As video cameras become more compact and the performance of mobile or motion cameras becomes more powerful, we are also increasingly confident in the professional production of these devices, and it is worth considering that we should purchase them as camera stabilizers.
The company is located in:
While the camera stabilizer market is in a period of drastic change, traditional mechanical camera stabilizers and emerging electronic camera stabilizers coexist. Before buying your camera stabilizer, you must know that no matter what type of camera stabilizer, there are some common The basic factors can affect the final stability.
Lens selection
The wider the viewing angle, the less noticeable the jitter of the picture. Most sport cameras have a widest viewing angle of at least 120 degrees, ensuring that everything you want to capture is included in the picture no matter where it is fixed. And if your hand is a large-size sensor camera or full-frame video camera, to obtain a 120 degree angle at least 10mm focal length lens is required. Whether the 10mm lens or sports camera will make the picture fisheye deformation, if the shooting scenery is not a problem, but if you shoot people will have strange distortion. Therefore, the ideal focal length camera stabilizer photography 18mm to 24mm, the focal length of the screen to stabilize and avoid distortion to find a balance between. If you use a sports camera, you can also set a narrower angle of view (such as 90 degrees).
Composition
Sounds like composition has little to do with the stability of the picture, but this is not the case. When using a camera stabilizer with a beat or wrap around, close-up close-ups often do not get good results because any displacement is magnified when the subject in the shot is too large, and the looser shots fit into the wider shots Can take more background) will have a better effect. This is also true when looking for reference objects. For example, parallel railings are ideal prospects to support the range and fluency of movement, but they are more likely to be counterproductive if technology is not in place. A single grid of railings such as Graduations generally make it easier for viewers to "measure" the jitter of the operator's pace.
Center of gravity settings
Whether it is a mechanical camera stabilizer or an electronic camera stabilizer, it is important to adjust the camera to the proper center of gravity. Conventional mechanical camera stabilizers, bow-and-rod, or full-fledged dual-damper Steadicam, can cause rotation or skewing of the balance bar if the center of gravity of the camera is not in position. As for the electronic camera stabilizer, the camera center of gravity deviations over the General Assembly to increase the burden on the motor, causing motor jitter, leveling, or even reduce the life of the camera stabilizer. The user needs to develop a habit of carefully adjusting the center of gravity and balance according to the manufacturer's instructions before each use, after changing the camera or installing accessories that affect the balance (such as extra batteries, microphones, headlights, etc.) Need to re-adjust.
Posture and pace
camera stabilizer core operating skills is the posture and pace, the most basic is to use the body to filter a layer of vibration, such as squatting, broken step, his hands bent, try to keep the stability of the camera stabilizer during exercise. Mechanical camera stabilizers often require painstaking training to adapt and master the technology. Although electronic camera stabilizers are easy to use, triaxial designs often can not filter vertical vibrations and require some practice to achieve truly smooth and smooth images. In addition, no matter what camera stabilizer is extremely costly exercise, to find their own comfortable posture is also very important.
