Both amateur photographers and professional camera users are well aware of the difficulties that arise in the process of shooting directly from the hands. Firstly, there is a high chance of obtaining a blurry picture, and secondly, even in the absence of a clear turbidity effect, it is more likely that the frame will not be sharp enough. Eliminate these troubles helps the stabilizer for the camera, which may have different designs, but serves one purpose - to create optimal physical conditions when fixing the frame.
The purpose of the stabilizer
Use this technology should be in cases where there is a risk of image quality distortion due to unintentional movement of the device. Optical stabilization compensates for angles of movement and eliminates camera shake in order to prevent blurry images at slow shutter speeds. It is important to understand that the presence of this function in the camera practically does not entail negative operating factors, so it certainly will not be superfluous. Another thing is that in some cases, the stabilizer for the camera does not save the situation, and can often be replaced with an ordinary tripod. Although to obtain high-quality images, it is still recommended to combine different methods of stabilization and reduction of the effects of jitter.
Camera Stabilizer
In the traditional version, the optical stabilization module is integrated into the lens of the device and represents a whole set of functional components. In particular, this complex is formed by a movable optical element in the form of a lens, which can be included in the optical system of the lens. The stabilizer also includes angular velocity sensors that record the parameters of the camera’s vibrations, which allows the system to adjust the optimal characteristics of the balancer. An important part, which also provides a camera stabilizer, is the electromagnet. Thanks to this detail, the optical element is moved based on readings from the above sensors. The microcircuit is responsible for coordinating the individual components of the system: the overall quality of the stabilizer’s work largely depends on its function.
Varieties of systems
High-level stabilizers are usually divided into two types - Nikon VR systems and IS modules, developed by Canon specialists. Often the end results of both systems have similar quality - especially in the eyes of lay people. An important feature of these systems is the ability to improve the quality of shooting in low light. A radical departure from this principle of integrated anti-vibration concept was the manual stabilizer for the camera, which in essence is a more ergonomic version of the tripod. Typically, such devices, called steadicam, are used to equip cameras, but recently, camera users have increasingly acquired them.
Another direction is the stabilization system used in SLR cameras from Sony and Olympus. In this case, the stabilizer for the camera is not built into the lens, but into the matrix base of the device. The advantages of such solutions include the compatibility of the module with almost all lenses, since the system interacts not with optics, but with the filling of the main device.
Modes of operation with a stabilizer
As a rule, there are two modes in which the camera uses the stabilizer function - frame and continuous. The best quality allows you to get the first single mode, because in the process of using it, the camera, roughly speaking, “freezes” until the moment the picture is taken. But the continuous format of the stabilization system can be justified if you need to take several photos during a dynamic shooting in a short period of time. To improve the quality of such shooting, it is recommended to use accessories for the camera in the form of the same manual stabilizer. The main correction module will eliminate significant and sharp deviations, and the tripod initially minimizes them. But even with such support, you should not count on creating high-quality images.
How to make a stabilizer with your own hands
It is almost impossible to implement an integrated module for the lens or camera matrix with your own hands, but it makes sense to try the technology for creating the same steadicam. In essence, a simple stabilizer should be obtained, leveling the effect of camera shake. The work will require a main metal rod, on which equipment will be mounted to hold the camera, bearings, as well as devices for manipulating the mechanism.
So, the essence of the design will be to reduce the vibrations transmitted to the camera by hand during the shooting process. The main component of the system will be the base damping vibrations. It is formed by a set of weights, the mass of which can be varied, and a system of bearings fixed at the points of rotation of the chamber relative to the axis of the rod. So that a homemade stabilizer does not fail at the right time due to a miscalculation in the power structure, reliable locks of its individual parts should also be provided. Since both the boom and associated equipment will not be subjected to severe loads, you can be limited to conventional mounting brackets. In addition, it is important to supplement the design with ergonomic handles, as during long-term shooting, fatigue from holding can increase the amplitude of oscillations.
How much does a camera stabilizer cost
The simplest steadicam models can be purchased for 1.5-2 thousand rubles. This can be a universal device that is suitable for almost all camera models. In the middle price segment, higher-quality and ergonomic designs with a cost of more than 5 thousand are offered. It makes sense to pay attention to the integrated stabilizer for the camera, which will consist of an integrated module, manual damping equipment and a floor rod. Such kits already cost about 10-15 thousand.
Conclusion
In choosing a stabilizer, a lot depends on the shooting conditions. If we are talking about “field” conditions and a dynamic photo hunting format, then you can not do without an integrated module in the matrix or camera lens. However, in a home or studio environment, external accessories for the camera in the form of the same rod or steadicam will also help. Here, much will depend on the organization of filming. Also, the shutter speed will affect the quality of pictures - the period of time during which the device focuses on the subject without corrections. The longer it is, the higher the chance of getting a high-quality image even without the use of stabilization systems.
