Dv Filming "eight Stable" Law Cautiously Film
With the popularity of DV, more and more friends with a small DV camera home wedding, birthday party or scenery and so on. However, most novice shooting DV clips of their images are different degrees of jitter conditions.
How in the short term to upgrade their camera, prevent picture shake it?
I. Stable self?? Hold good DV machine
Play DV and DC play the same hands are particular about the effort, as long as the hands holding the device steady enough, the screen will not shake up naturally. DV is now the main single hand held control, although the left hand do not adjust the focus when shooting, but the DV should be the same style as both hands, right wrist with his left hand to help to increase stability. If the standing shooting, the natural separation of the legs to about shoulder width, toes slightly out separately, stand firm, keep their balance.
DV for shoulder-fired, usually with both hands gripping film. Hold the camera with both hands, the eyes closely aligns viewfinder lenses, so they can keep the stability of DV machines.
II Stable support?? With a good tripod
Shoujin another great endurance time no matter how good it is not possible to maintain a fixed position. So take a long time in fixed-screen shooting, such as shooting weddings, birthday parties, concerts, stage, etc., be sure to use a tripod, its role is to support the equipment, maintain stability, while allowing your hands a break.
III Steady vibration?? Open Optical Image Stabilization
Present, many machines have the image stabilizer DV compensation. DV machine judder through the built-in sensor to perceived slight vibration, and the best resolution and focus to maintain the current situation, the camera's motor drive camera group, resulting in a completely opposite amplitude vibration, automatic offset external jitter unstable situation on the screen to compensate. Although the image stabilization function in the suppression of the image caused by shaking the machine instability, but this inhibitory effect is very limited, not universal, so stability is the benevolent hand.
IV Stable picture?? Use wide-angle shooting
DC The players all know, the longer the focal length when shooting an object, the smaller the angle, body shaking slightly transmission to the screen, shaking very powerful, is the so-called "lost tackled solely of a thousand miles" is the truth . With DV and DC is the same as in the use of telephoto shooting, the slight vibration will result in a larger screen jitter; the focus of wide-angle lens with a short film, due to a larger perspective, focus is relatively easy, even when shooting DV machine there shaking, the picture is not easy to perceive.
V. Stable composition? Shoot the right content
DV footage, its composition is very important, the picture composition instability can not properly convey useful information to the audience. Some of the more advanced DV machines in the viewfinder and LCD display guides can help us to maintain the level of DV machines. In fact, with or without auxiliary line, as long as the attention to use screen "horizontal reference line" (such as the horizon), "vertical reference line" (such as telephone poles, buildings), or the LCD viewfinder can be parallel to the border. In the lens when shooting at the target, fixed shooting, do not push the lens up and down in recent widening of about sweeping action or photo. Screen so as not to affect the stability, the screen changes.
Station if you can take panoramic point, the screen will be even richer.
VI Stability of the lens?? Caution zoom lens
General, unless the factors that can not close because of the site, This will be the screen using the zoom lens to adjust to the size you want. But remember not to stand still use the zoom zoom zooming take effect, which often cause picture distortion and jitter.
Therefore, the correct way is to zoom "shot? Stop? Zoom? Shot" if they are too awkward between the lens, consider the use of clips in the latter part of the transition effect of convergence. Novice at shooting and more fixed lens, can increase the stability of the screen, a screen then a screen to shoot pictures with different sizes of convergence, so as not to overlook the big picture suddenly small, zooming changing. For the expression of the same scene shot, might use different angles and distances will focus photography, the effect may be better.
VII Stable action?? Shoot good dynamic lens
Shooting sliding lens, the best choice for auto-focus, so that when the camera is in autofocus mode, without any high-speed auto-focus camera can adjust the focus to the best. In the push-pull process, the picture composition should always pay attention to maintaining the main structure of the central position of the screen, and shooting will not move up or down. In addition, the push and pull of the process must be slow, the faster the more prone to screen jitter situation.
There is also a dynamic lens, the body alone to complete the shooting small moving objects with different details of the static, dynamic film that must pay attention to maintain a constant speed, the distance between the lens and target. Also pay attention to the continuity of movement in order to maintain the continuity of close-up pictures.
VIII Stable switching time?? Master shooting time
For photograph opportunity is important, too fast often seemed very abrupt, did not understand before and after images to see; the other hand, if too much time switching lenses, the impact of watching enthusiasm, see annoying. Therefore, to master every shot was really careful pondering.
General, for the convenience of the audience to understand the screen, switch to another screen before the best shot to stay for a few seconds, the time under different circumstances stay is different; principle objective of the more recent shorter; Feature 2 to 3 seconds, in close-range 3 ~ 4 seconds, medium shot 5 or 6 seconds, panorama 6 ~ 7 seconds, a large panoramic 6 to 11 seconds, the camera with generally 4 ~ 6 seconds is appropriate. For example: close-static image generally 2 to 3 seconds; while shooting landscapes, the most appropriate shooting time is 10 seconds. If the shooting video, you need to run the speed element of choice the right time.
Stability of the screen is the key to a successful DV film. The audience, every shot can be balanced from start to finish, than casually shaking bumps more valuable.
