Low Shutter Speed的意思|示意

Conversely, you might use a slow shutter speed to compensate for low light conditions-the longer the hole is open, the more light gets in, right?

反过来说，你可以用慢速快门来补偿暗光条件。

By bringing the shutter speed low enough that available light registers on the image, you can retain most of the mood of a setting by not over-powering it with flash.

通过将快门速度降的足够低，并且闪灯不把背景打的过亮，你就能保留背景的大部分的细节。
