Nikon D90 18- 105, how to adjust the depth of field to make the photographer look good.

This kind of lens with large zoom ratio has poor ability to control the depth of field, and the effect may not be ideal.

But you can always try to get a shallow depth of field with your own strength:

1 Open the aperture to the maximum, you can open it to f2.8, never use f4.0；;

2. Adjust the focal length to the longest 105 mm. If the scene is incomplete, the photographer should try to retreat.

If possible, try to shorten the distance between the photographer and the subject.

If the above three items are available at the same time, better depth of field (mostly shallow depth of field) can be obtained.

If the photographer needs a large depth of field, it will be much easier, and the above three things can be done backwards; And if the aperture is reduced to f 16 or less (such as f22), the depth of field effect will be much greater.
