这在任何光圈和焦距上都适用，只不过光圈越小、焦距越短，景深越大，你能够拍摄的清晰长度就越大。

This works for all apertures and focal lengths, but the smaller the aperture and the shorter the focal length, and the greater the distance you shoot at, the greater the depth of field.

最简单的办法是选用最小的光圈设定（镜头上显示的最大的数字），光圈越小，你所获得照片的景深就会越大。

The simplest way to do this is to choose a small Aperture setting (a large number) as the smaller your aperture the greater the depth of field in your shots.
