摄影中的概念

 

 

 

 

 

快门速度

 

 

 

 

 

快门速度指快门开关所需的时间量。它控制光线通过光圈到达图像传

感器之前的光量。

 

 

 

 

 

通常，快门速度可手动调整。快门速度的测量单位称为“曝光值”

（EV），该值以 1 s、1/2 s、1/4 s、1/8 s、1/15 s、1/1000 s、

1/2000 s 为间隔进行标记，以此类推。

因此，快门速度越快，允许进入的光量越少。 同样，快门速度越慢， 允许进入的光量越多。

下图所示照片表示较慢的快门速度允许光有更多时间进入相机。这可 使移动中的物体增加运动模糊效果。反之，较快的快门速度允许光进 入的时间更少，并会更容易定住运动中的拍摄对象。
