《01控制反射玻璃》 =====本中英双语字幕由CGSUB.com独家制作发布===== A big issue that filmmakers have a love-hate relationship with is reflections. 那人又爱又恨的一个大问题的思考。
【更多中文字幕请访问CGSUB.COM】 It's like this crazy hot and cold relationship where sometimes we want reflections around and other times we want them to get lost. 就像这个疯狂的冷与热的关系，有时我们需要思考在其他时间我们希望他们迷路了。
【作品只能交流学习，不得用于任何其它用途！】 【字幕唯一发布站CGSUB.COM】 So with this complex love-hate relationship with reflections in mind, one of the very first accessories I would get with any camera is a circular, polarizer filter. 所以这种爱恨交织的复杂的反射在心的关系，一个非常配件我会得到任何相机是一个圆偏光过滤器。
After the ubiquitous ND filter, which is already built into many cameras. 无处不在的ND滤光片后，已集成在许多相机内部。
I think the circular polarizer filter is a close second for all around practical usefulness and production value bang for the buck. 我想圆偏光过滤器是一个接近第二周围所有的实用性和降压生产价值爆炸。
Polarizers have several uses, but the most common is to cut down reflections. 偏振片有多种用途，但最常见的是减少反射。
And no matter what situation you're in, there are almost always reflections of one type or another on car windshields, glasses, windows, water, even on faces. 无论什么情况，你在思考，几乎总是有一种或另一种在汽车的挡风玻璃，玻璃，窗户，水，甚至在脸上。
Well a polarizer filter is the one thing that can deal with all those issues quickly and effectively and help you control the level of reflection in almost any scene. 一个偏振滤光器是唯一能处理所有这些问题，快速有效地帮助你控制几乎在任何场景反射水平。
So let's take a closeup look at the handy circular polarizer filter in one of the most common scenarios and that's shooting through glass. 所以让我们方便的圆偏振滤光器特写看起来在一个最常见的情形，是透过玻璃拍摄。
Let's start with the standard window scene. 让我们用标准的窗口现场开始。
Here's our scene without a polarizer. 这是我们的现场无偏振片。
As you can see, we don't see much of our actor's performance here. 正如你所看到的，我们看不到我们的许多演员的表演在这里。
Instead we mostly see the reflection in the glass outside of the office. 相反，我们主要看到反射在办公室外面的玻璃。
So things like the expression on their face, wardrobe, and important props in the scene are all much harder for the audience to see. 所以这样的事情在他们的脸上，表达的衣柜，并在场景中的重要道具，都很难让观众看到。
Now if you don't have a polarizer filter, you can try things like different camera angles, or maybe a large flag or other types of rigging to block light from hitting the window, but either of these solutions would be more time consuming, and it's still hit or miss as to whether it would even work to cut out a good deal of the reflection. 现在，如果你没有一个偏振滤光器，你可以试着像拍摄角度不同， 或者可能是一个大的标志或其他类型的操纵光线打到窗，但无论这些解决方案会耗费更多的时间， 和它仍然击中或错过对是否会努力缩减一个好的反射。
So we're going to do what we gotta do, just like the pros, and bust out a circular polarizer. 所以我们要做我们要做的，只是一样的利弊，并摆出圆偏振器。
Once your polarizer is on the lens, look through the viewfinder as you slowly spin it and you will instantly see the value of the polarizer as it significantly reduces the level of reflection, so that we now see our actor clearly on the other side of that glass window. 一旦你的偏振器的透镜，观察取景器，当你慢慢旋转，你会马上看到偏振片的值显着降低水平的反映， 所以，我们看到我们的演员清楚的玻璃窗的另一面。
Now, another common scenario that calls for a polarizing filter is car shots. 现在，另一种常见的情况，需要一个偏振滤光器是汽车的镜头。
Driving shots are a nice way to keep things dynamic onscreen, with motion and changing light and backgrounds. 驱动镜头是一个很好的方法来保持动态屏幕，运动和变化的光和背景。
【本字中文幕由 ACELY 翻译制作】 【请认准唯一发布站www.CGSUB.com】 However, not unlike the office scene I just showed you, many people go to shoot their car scenes only to discover that all they're really shooting is the reflection of the sky and trees above, and very little of the actors behind the glass. 然而，不像我刚才给你办公室的场景，许多人去拍他们的车的场景，却发现他们真的拍摄是天空和 树上的反射，和非常小的玻璃后面的演员。
Again, a circular polarizer is just the solution. 再次，一个圆形偏振器只是解决方案。
The beauty of this type of polarizer is that it's not an either or choice of reflection or no reflection. 这种类型的偏光片之美在于它不是一个非此即彼的选择反射或不反射。
Instead it allows you to control the degree of reflection. 相反，它允许你控制的反射程度。
Those leaves and sky reflecting on the windows are often a beautiful and complementary visual element to the story. 那些叶子和天空反射在窗户上往往是一个美丽的和互补的视觉元素的故事。
They also help to aid the sense of motion. 他们也帮助援助的运动感。
So many times you'll find that sweet spot that allows some reflection Just not enough to obscure your actor's performances. 很多时候你会发现甜蜜点，允许一些反射不足以掩盖你的演员的表演。
Remember, there's not a right or wrong way, per se. 记住，没有正确或错误的方式，本身。
Just a right or wrong level of reflection for the particular visual story you're trying to tell in any given scene. 只是一个正确的或错误的反思水平为特定的视觉你想讲的故事在任何给定的场景。
Sometimes that will mean a full focus on the reflections in the scene. 有时，这将意味着在场景中的反射全聚焦。
And other times it may mean eliminating those reflections. 有时这可能意味着消除那些思考。
It's your thing so do what you want to do. 这是你的事，做你想做的事。
The important thing to take away is that only a circular polarizer allows you the choice to easily control reflections on glass. 重要的是要带走的是只有一个圆极化器允许你选择容易控制反射玻璃。
And to be clear, removing reflections is not something that you can do in post. 要清楚，去思考是不是你可以做后。
They don't have an app for that, at least not yet. 他们没有这样的一个工具，至少目前还没有。
So a polarizer is a vital tool to have. 所以一个偏振器是有一个重要的工具。
When you need to manage reflections in glass surfaces. 当你需要在玻璃表面的管理的思考。
But controlling reflections is just the most popular use of polarizers. 但控制反射偏振器是最流行的使用。
In future segments I'm going to show you how a polarizer can also be a handy tool. 在未来的片段，我要告诉你一个偏振片也可以是一个有用的工具。
To help you control the look of water and the sky. 为了帮助你控制水的外观和天空。
