夜间摄影与白天摄影受到同样条件的约束——即光圈，快门速度，感光度——不过它对于这些参数的控制都要达到极致。

Night photography is subject to the same set of constraints as daylight photography - namely aperture, shutter speed and light sensitivity - although these are all often pushed to their extremes.

这门课同样适合那些懂得IS O感光度、光圈、快门速度、白平衡等摄影知识并能用自己的数码单反或桥梁相机设置这些参数的同学。

It is ideal for those who have an understanding of ISO, aperture, shutter speed, white balance and how to change these on your digital SLR or bridge camera.
