How to shoot with blurred background? Photographic skills help you get a sense of fantasy.

How to shoot with fuzzy background, fuzzy background shooting is now a favorite way for many photographers. But how to take good-looking blurred background photos requires some photography skills.

1. Jiao Xu

Jiao Xu means that the subject is out of the clear focus range of the photographic lens, and the image is blurred on the picture of the photographic work. Because this image is out of focus, it is called Jiao Xu. There are two types of focus defects: front focus defects and back focus defects. The so-called lack of front focus means that the scene in front of the focus is blurred on the screen with the focus as the center; The so-called lack of back focus means that the scene behind the focus is not clear on the screen.

There are two main ways to blur the picture when shooting:

One is to shoot with a large aperture. This is because the larger the aperture of a photographic lens, the smaller the depth of field. Focusing on the subject, the scenery far away from the subject is blurred. If the subject is in the middle position and focuses on the subject, the real subject, the scenery close to the subject and far away from the subject are all blurred; If the subject is in a panoramic or distant position, the subject is the focus, the subject is real, and the scenery close to the subject is blurred.

Second, the use of medium and long focal length photographic lens causes caustics, because the longer the focal length of the photographic lens, the smaller the depth of field, so the long focal length photographic lens can create a caustics effect.

In photography creation, if the telephoto camera lens is combined with the large aperture, it will be icing on the cake and achieve better caustics. The blade of grass uses a combination of large aperture and long focal length to make the objects outside the clear range behind the focus center form a blurred image, which makes the picture of this photographic work have obvious caustics effect and makes the grass with raindrops more prominent.

2. Things move in vain

When the camera lens shoots at a moving object, some images in the photographic picture become blurred due to the motion of the subject, which is called insufficient motion of the object. In photography, the combination of motion and static can also increase the interest of the picture. This trick is often used to shoot running horses, speeding cars and athletes' hands and feet in stadiums and gymnasiums to show the specific atmosphere of specific occasions.

3. Mirror Motion Defect

When an object rides on a moving object, such as a car, a boat, an airplane, a horse, etc. The phenomenon of blurred images caused by shooting ground scenes is called mirror motion virtual. Because these moving objects are very fast, when shooting with these objects, the foreground will move forward quickly and the foreground will move backward quickly. Only when the moving speed of the subject forward and backward is synchronized with the moving object, the subject is clear, and other unsynchronized ones will produce blurred lines in different degrees. In addition, zooming with a zoom lens (that is, zooming while pressing the shutter) will also produce a mirror illusion of radioactive blurred lines on the screen.

4. Insufficient double action

When shooting a moving subject, the camera lens moves with the movement of the subject, and the shutter button is pressed during the movement. This method will make the subject's image in the photographic picture clear, while the set-off image is fuzzy, leaving a sense of movement to the viewer visually.

The above three moves can also be collectively referred to as dynamic virtual. Therefore, motion blur is a blur phenomenon caused by the motion of the subject or camera when some scenes on the picture of a photographic work are shot.

In addition to the fuzzy phenomenon caused by the movement of people or things, some common natural phenomena can also be used flexibly to make your virtual tricks more endless.

5. insufficient clouds

In landscape photography, if clouds are used to cover up, the mountains and trees will be virtual and real, resulting in a Penglai fairyland-like artistic conception, which is also called cloud deficiency. As shown in the above picture, this photo is a picture of looming mountains and rolling clouds, which makes people feel like they are in a fairyland.

6. Insufficient dust

Although dust is quite annoying, it is essential to blur some scenes in the picture with flying dust. For example, when the air is full of dust due to Ma Benteng, speeding cars and strong winds, the effect of insufficient dust can be formed, and an atmosphere in a special environment can be created.

7. wind deficiency

Using some smaller plants to shake and tremble constantly under strong wind makes the images on the pictures of photographic works blurred, which is called wind deficiency. For example, under the strong wind, the branches keep swinging and the wheat seedlings in the wheat field roll.

8. Fog deficiency

Fog deficiency refers to the use of the aerial perspective effect of fog to give a hazy atmosphere to the photographic works, making them poetic and picturesque, thus arousing the association of the viewers. This trick is often used in landscape photography. Under the cover of fog, the medium and long-range subjects are illusory, hazy and mysterious.

9. insufficient light

Optical illusion is an illusory scene caused by light. Some subjects have a bright light path due to the transmission of light. Under the cover of the light path, the subjects are blurred, which makes the pictures of photographic works have a special charm effect. Just like the morning light, although the rising sun is not directly photographed, the light passing through the branches still shows the scene that the sun has just jumped out of the horizon to be radiant, giving people a feeling that everything is about to recover.

10. Mirror defect

Atomizing mirror: Using atomizing mirror to shoot objects that are not covered by fog can shoot foggy effect.

Halo lens: shooting with halo lens can eliminate some defects of the subject's performance, reduce the contrast and make the tone softer. Widely used in portrait photography, especially wedding photography. Do you know how those beautiful women with flawless faces come from in the advertising picture? Most of them use this weapon.

Halo mirror: shooting with halo mirror can make the central part of the picture clear and the surrounding areas blurred.
