改变感光度来符合拍摄时的环境光线

基础知识，铁三角关系。

光圈越大，进入相机的光越多，同样的感光、快门速度，照片就越亮。

Many years ago, I worked for my parents who own a video production company. Because it is a family business, you inevitably end up wearing many hats and being the czar of many different jobs. I mainly managed projects and worked as a video editor. On production, there were times that I was called on to work as an audio tech and was made to wear headphones on long production days. In those days, having a really good set of headphones that picked up every nuance of sound was essential to making sure the client got what they needed.
