exposure time

基本解释

This means that exposure time can be extremely short even in poorly lit conditions.
这意味着，即使在光线并不足的条件下，曝光时间仍然可以极短。
You pick the exposure time you want—short or long—and the camera will do the rest, like set the aperture.
你可以选择你想要的曝光时间——短或长——其他的事情（例如设置光圈）则交给相机来做。
It has a wide-aperture lens to capture as much light as possible, and the technology requires no clunky auto-focus mechanism. It adjusts exposure time automatically.
它的大光圈镜头可以摄入尽可能大的光量，所用技术并不需要笨重的自动对焦系统，曝光时间也是自动调节。

Now, why is the time less on second exposure?
为什么再次免疫花费的时间少呢?
