How to set the aperture and shutter for SLR photography?

When shooting portraits, if you are looking for a clean picture in which the subject (figure) is prominent, then shooting with a lens with a large aperture and a long focal length will get the ideal effect. As far as the body and lens you have now are concerned, using the aperture at the 55MM end of the lens to 5.6 is the best blur effect.

Of course, taking a portrait should not only blur the background, but also grasp your own feelings if you want to take a good portrait. Look at the good films taken by experts, and you will understand how to take good portraits. Sometimes the background needs to be blurred, and sometimes it needs to be clear before and after, depending on the subject you want to shoot.

The scenery is the same. In many cases, it is necessary to be clear before and after, so try to use a small aperture, such as the aperture setting of F8.0~F22. The choice of focal length mainly depends on the scenery you take. Of course, sometimes you need to take some sketches, so you need to open the aperture to blur the background.

In fact, the setting of aperture and shutter can't be explained clearly in one or two sentences. This is a book.

Since you are a novice, you can buy some books on the basic knowledge of cameras and read them first to understand what aperture is and what shutter is, and then you can know what combination to use in what occasion. It is recommended that you take photos with files (aperture first), that is, manually set the aperture and let the camera automatically set the shutter according to the metering results.
