How to control the depth of field when taking pictures? It is enough to master these three points.

Especially for beginners of photography, fuzzy background is very effective. In the field of photography, this effect is called "shallow depth of field", and it is not difficult to shoot this effect. Depth of field refers to "the range of clear imaging before and after the focus". How to control the depth of field when taking pictures? It is enough to master these three points, and I hope it will help everyone.

Influence of One Distance and Different Distance on Depth of Field

How to effectively control the depth of field? Different distances affect the depth of field. This distance is the distance between the subject and the background. If you want to highlight the portrait, you often have to blur the background to highlight the portrait. You just need a small depth of field. At this time, the subject needs to stay away from the background. If you want to shoot the iconic background, you need a great depth of field.

Distance between two shots, close-up and long-distance portrait

This distance is the distance between the camera and the subject, and the depth of field is controlled by adjusting the distance between the camera and the subject. The principle is similar to the imaging principle of our mirror. The farther the camera is from the subject, the shallower the depth of field is, but it should be noted that it cannot be less than the minimum focusing distance of the lens, otherwise the camera will not be able to focus, resulting in blurred photos; On the contrary, the farther the camera is from the subject, the deeper the depth of field we get.

Three apertures, the large aperture on the left and the small aperture on the right.

How to control depth of field in photography? Aperture can control the amount of light entering the camera and the amount of scenery seen through the aperture. The large aperture is closer because of the influence of light imaging, while the small aperture can see many clear pictures in the distance. This is similar to the principle of small aperture imaging, and we can accommodate more things when we look far away.
