What are the types of stabilization? When to use stabilization? Why do we properly stabilized and what is the best? These and other questions will find answers in our guide.

Image Stabilization. Well if it is wrong when it is not. Everyone knows what it is, but not everyone knows what that is exactly. In this short tutorial we will try to clarify this issue and describe the different types of stabilization and advise that will be the best. It should be recalled that we have to deal with the stabilization in the lenses or cameras. This is important because sellers often indicate that the camera is stabilizing, referring to the lens. Meanwhile, that, for example. Kitowy lens has a stabilization does not mean that it also has a camera – so you should check before buying.

types of stabilization

Digital stabilization. As the name suggests, in her case, the image is digitally stabilized. This may lead to a deterioration of image quality – if, for example., The camera uses "cropu" or the higher resolution makes the image below in order to properly wystabilizować image. This type of stabilization can be found in most of the low-cost models. Unfortunately, the disadvantage of this approach is that the effects are not the best use of the stabilization is often associated with the deterioration of image quality. Optical Stabilization. In her case, instead of running digital we have to deal with the work of optics. It is a solution for which we do not have to deal with the deterioration of image quality, so it is a much better option than digital stabilization. Sometimes, however, its strength is not too large, and therefore the effects are not much visible. The mechanical stabilization / 5-axis. This is the most advanced type of stability, however, is seen only on more expensive camera models – the most in bezlusterkowcach, very rarely SLR. Thanks to the special mechanism of the matrix camera is stabilized in a 5-axes (directions). It works as if we have suspended the matrix in several springs, which would isolate it from the vibrations of the body. It's just that this system is based on motors, mechanical, and so it is even more efficient. Dual IS. The term most commonly used by Panasonic, but becomes more and more current. They can be considered as a system of dual stabilization. In this case, stabilize the camera works with the stabilization in the lens. By combining both systems, image stabilization is even more fluid and unmoved. The solution it is being used in new models of Panasonic, but also Sony.

stabilization force

Value was determined, according to which measures the performance of stabilization in the camera or lens. This value I give the designation "EV". In theory it is a reference to the exposure time. So the strength 2EV will extend about two degrees of exposure strength 4EV four degrees of exposure etc. Usually yield stability varies from 2 to 5 EV. As in many other cases – the more, the better.

When you use the stabilization

Usually we associate stabilization function, which allows the screen vibrates less, is more stable. And indeed, that is for shooting. But what does it matter when you take pictures? Thanks to the use of stabilization, we can slightly extend the exposure time of the shooting hand. A longer exposure time results in the camera must be positioned securely – otherwise shake our hands will result in smearing and defocus the image. Therefore pictures with slow shutter speeds are usually done with a tripod. However, if stabilization is sufficiently powerful, you can slightly increase the exposure time, even when shooting handheld. Long exposure time gives us a clearer picture, but also allows for some interesting creative effects such as blur of light.

When recording a stabilization will not always help – may sometimes interfere. If you use the Steadicam, included stabilization in the lens may malfunction, which will result sometimes the presence of "jelly" in the image. A similar effect will take place when the vibrations are too much – when we run with the camera in his hand. Then the picture will be more stable in theory, but you can see it will be precisely the effect of "jelly" – it can be seen even in the above mentioned film sample. stabilization can give very good results, but remember, however, that it has some limitations. Never replace us Steadicam or a tripod, although in many cases will help a lot.
