Under those conditions photographers shoot with a fast exposure time and small aperture. That makes it impossible to capture faint objects in a dark background, such as stars.───在这种情况下拍摄者会使用很短的快门时间并调小光圈，这样就不可能拍摄到黑色背景上那些很暗的物体，如星星。
Telescopes with small (sometimes called "fast") focal ratios do, however, produce brighter images of extended objects on film, and thus require shorter exposure times.───小(有时候称“快”)焦比的望远镜确实能够在底片上呈现出更亮的图像，因此需要的曝光时间可以更短。
