现在你已经了解了这两个参数——快门速度和光圈大小，他们从本质上来说有同一个功能：控制进入相机的光线总量。
So you have these two parameters, shutter speed and aperture size, both of which do essentially the same thing: control how much light gets in.
这只适用于那些使用全功能相机的人，但是尽可能的使用最大光圈能够确保最大亮度，来让焦点尽量聚焦在前景上。
This will only apply to those using full cameras, but using the widest aperture available to you will ensure the maximum level of light, allowing the majority of focus on the foreground.
通过先进的电子光线控制(elc)的功能，可以在室内应用时使用固定光圈镜头。
Through advanced electronic light control (ELC) function, you can use in indoor applications fixed aperture lens.
