The device also has a diopter adjustment built in, so people who wear glasses or contact can use it without wearing additional vision correction.

该设备还内置了屈光度调节功能，因此佩戴眼镜或接触的人无需佩戴额外的视力矫正即可使用它。

There's also an uncannyness that is inherent to split diopter shots.

- 分割 diopter 拍摄固有的有种诡异感。

So it's very important to have a kind of stable stand for it, and that they just borrowed from standard diopters, standard implements.

所以有稳定的底座非常重要，他们只是借用了标准屈光度和标准工具。

Diopter strengths are like most lenses measured in meters.

- 屈光度强度与大多数透镜样，以米为单位进行测量。

One of the earlier split diopter shots from 'Citizen Kane' was in fact a version of this, where two shots were composited together.

《公民凯恩》中较早的分裂双筒镜头实际上就是这种效果的版本，其中两镜头被合成在起。

But on the 1940 film, 'The Long Voyage Home', Toland used a different technique to achieve a similar effect using a split diopter to achieve this shot.

然而在1940年的电影《漫长的航程》中，德采用了不同的技术， 通过使用分光镜来达到类似的效果， 从而实现了这镜头。

In this shot, Burum uses a split diopter to keep the waitress in focus.

在这镜头中，Burum 使用了分隔透镜来保持女服务员的清晰对焦。

At their core, split diopters enable dynamic compositions along the Z axis of a frame rather than point an audience's attention to one subject, a split diopter creates multiple planes of action.

- 本质上， 分体式取景器能在画面的Z轴上实现动态构图， 而不是将观众的注意力集中在单主体上；它创造出多动作层面。

But first, let's look at how to use a split diopter.

首先，我们来看看如何使用分光镜。

This is because the diopter portion of the image will have a very shallow depth of field, and a higher stop will make it a little deeper so that focus issues can be more easily avoided.

这是因为图像中使用近摄镜的部分景深非常浅，而较高的光圈值会使景深稍微加深，从而更容易避免对焦问题。

The diopter isn't very strong, so its presence is subtle, but the actors still have to hit their exact marks to stay in focus.

分光镜的强度并不高， 因此其效果较为微妙，但演员们仍需精准站位， 以确保始终处于焦点之中。

The use of split diopters began to spread.

分隔 diopters 的使用开始流行。

As filmmakers have experimented with split diopter, variations on the shot have arisen.

随着电影制作人对分裂 diopter 进行实验，这种镜头的变化形式也随之出现。

In cinematography, diopter is technically a misnomer for a close-up adapter.

- 在电影摄影中，“屈光度”实际上是对近摄接圈的技术性误称。

In this scene from 'Manhattan', we see a rare example of a moving shot with complex blocking that uses a split diopter.

在《曼哈顿》的这场景中，我们罕见地看到了运用分光镜的复杂移动镜头，其布景设计精巧。

One of the most attention-grabbing techniques in DP's arsenal is the split diopter shot, which can add an entirely new layer to a frame.

在DP的众多引人注目的技巧中， 分光镜镜头堪称绝，它能为画面增添全新的层次。

The image of split diopter achieves varies based on the lens focal strength.

- 分光镜效果的图像会因镜头焦距强度的不同而变化。

While a one-half diopter will allow objects two meters away to be in focus.

而使用半屈光度（one-half diopter）的透镜，则能让两米远的物体保持清晰对焦。

With a plus one diopter objects, one meter away will be in focus.

使用正屈光度的透镜，米远的物体将处于焦点上。

In this shot from 'Come and See' a split diopter is used to illustrate the protagonist's devastation and put the audience on edge with him.

在这部《来吧，看看》的镜头中，使用了分裂 diopter 来表现主角的绝望，并让观众与他同感到紧张。
