正如我们前面所提到的,平移是像移动 我们的头从左向右和背面。 平移可以用来跟踪对象,因为这使得它的方式在整个帧。 或者,它也可以用来重定向观众的注意力,露出新的信息。 倾斜是象移动了头部上下移动。 这种技术可以用于使观察者进入现场,强调重要性或意义 的主题的,露出来的信息到 现场,或揭示的对象的垂直尺寸。

我们经常看到平移和倾斜,被一起使用。 由于平移和倾斜模仿的运动 人的脖子,我们常常用它们来创建或重新创建 人物的角度来看,也叫过氧化值,或建立一个 意义上说,行动屏幕被别人发现。 当平移和倾斜,但同样重要的是 我们策划拍摄时考虑了相机的高度。 因为它将决定从那里观 ​​众观看我们的主题的观点。 一个简单的例子,看看这个。

相机的高度约为女孩的眼睛水平。 当我们倾斜向下或向上,结果是截然不同的。当倾斜时,它看起来像有人在看她的鞋子,然后她的脸。 当倾斜下来,好像有人看 建筑,突然发现有个女孩在等人。 平移用长镜头拍摄主体,增加了感知速度日 情绪,可以给人的印象是被摄对象被跟踪或监视。 摇摄,往往被视为摄像头编辑。

因为我们可以从受A到受B和回答 不中断现场的完整性。 通过这样做,我们可以添加一个图层现实主义,和 给人的印象,这种情况是发生在实时。 非常快锅也可以用来作为场景之间的过渡。 还有别的东西要考虑。 在水平或者垂直的速度,可以 在很大程度上影响对观众的感知效果。 缓慢平移或倾斜迫使观众参加的所有视觉信息场景的,因为它进入的帧。

快速平移或倾斜可以迷惑观众, 并摇晃他们的注意力集中到了新的起点。 为了捕捉真正平滑的运动,它是 必不可少的正确安装和制衡的三脚架。 我们需要微调紧张,所以三脚架做繁重的我们, 如果我们拥有的奢侈品挡住了我们的镜头,我们应该练习 动作多次,之前连 滚了摄像头,并相应地调整张力。 一般来说,我们希望用更少的张力设置三脚架的头 对于接近或快速移动的物体,并增加张力的动作迟缓。

额外的张力常常帮助,如果出于任何原因, 我们很难保持稳定的投篮, 有时出现这种情况有充分暗箱操作相机。 更多的,往往不是我们想要的平移和倾斜,以平稳和流畅,当然,除非该故事要求的相机抖动。

 

As we mentioned before, panning is like moving our head from left to right and back. Panning can be used to follow a subject as it makes its way across the frame. Or it can be also used to redirect the viewer’s attention to reveal new details. Tilting is like moving our head up and down. This technique can be used to bring the viewer into the scene, emphasize importance or significanceof the subject, reveal to details into the scene, or reveal the vertical size of an object.

We often see pan, and tilts being used together. Because the pan and tilt mimics the motion of the human neck, we often use them to create or recreate a character’s point of view, also called POV, or establish a sense that the action on screen is being observed by others. When panning and tilting, it is also important to consider the height of the camera when plotting our shots.As it will determine the perspective from where the audience views our subject. A quick example, check this out.

The camera’s height is about the girl’s eye level. When we tilt down or up, the results are drastically different. When tilting up, it looks like someone is looking at her shoes and then her face. When tilting down, it seems like someone is looking at the building and suddenly discovers there is a girl waiting for someone. Panning a subject with a long lens, increases the perceived speed of th emotion and can give the impression that the subject is being followed or watched. Panning, is often considered as in camera editing.

Since we can go from subject A to subject B and back to A. Without interrupting the integrity of the scene. By doing this, we can add a layer of realism, and give the impression that the situation is happening in real time.Very quick pans can also be used as transition between scenes. And there’s something else to consider. The speed of the pan or tilt, can greatly influence the perceived effect on the viewer. A slow pan or tilt forces the viewer to take in all the visual information of the scene as it enters the frame.

A fast pan or tilt can disorient the viewer, and jolt their attention to a new point of focus. In order to capture truly smooth movement it is essential to properly set up and counterbalance the tripod. We need to fine tune the tension, so the tripod does the heavy lifting for us. If we have the luxury blocking out our shots, we should practice the movement multiple times, before even rolling the camera, and adjust tension accordingly. Generally speaking, we want to set the tripod’s head with less tension for close or fast moving subjects, and increase the tension for slow movements.

Additional tension often helps if for any reason, we find it difficult to keep the shot steady. Sometimes this happens with fully rigged cameras. More often than not, we want panning as well as tilting to be steady and fluid, unless of course, the story calls for camera shake.
