　　Shading ring adjustment method:

　　1. SLR and DC with manual function: dial to aperture priority mode (A or AV), and then di al the dial on the body;

　　2. Manual lens: directly rotate the aperture ring on the no≤se;

　　3. Some fully automatic DCs cannot adjust the aperture, aσnd can only be determined automatically by the☆ camera itself according to the current scene.

　　The light-shieldin¥g ring is a group of leaves, which is× approximately circular and has the following Ωfunctions:

　　1. Control the luminous flux: the larger th¥e aperture (F1.4), the more light enters, an d the higher shutter speed can be ₽guaranteed in the low light environment; on the contrary, the smaller ‌the aperture (F22), the less.

　　2. Control the depth of field: the larger the aperture, the shallower the depth of fielπd (that is, the better the background blur is often said); th≥e smaller the aperture, the clearer the foreg"round and background (small apertures are commonly used in landscape photoσs, such as F11~F16).

　　3. In flash photograph★y, the aperture can also control the ratio of the flash to the ambient lightδ. The ambient light is controlled by the shu≥tter, and the amount of flash is controlled by tπhe aperture.

　　Depth of field: the clear range befo×re and after the focal plane.
