It's using a light meter and measuring the light in the scene and trusting that you're getting what you want.

这是使用曝光计测量场景中的光线，让你能够拍出预想的画面。

I dropped two light meters, I switched out a wrong lens and I punctured her mounts.

我摔了两个测光器 换错了一个镜头还弄坏了她的镜头转接环。

But we can't do that, our eyes aren't cameras or light meters or that little eyedropper tool in Photoshop.

但我们不能那样做，我们的眼睛不是相机或测光表或 Photoshop 中的小吸管工具。

Sure. Just a minute. Let me take my camera out of my backpack. Let's see. Turn it on, point, check the light meter, and, and...huh?

没问题。稍等一下。让我把相机从我的背包里拿出来。我看看。打开电源、取景、检查光圈和… … 和… … 呃？
