Is there any good way to "blur" photos with mobile phones?

There are two ways to blur photos with mobile phones. First, take blurred photos in the early stage; Second, the effect of repairing "blur" with mobile phone in the later stage.

1, pre-shooting, direct elimination of blur, with the following skills, as well as mobile phone settings:

(1) Set the camera of the mobile phone to a large aperture, and focus on the object or model to be photographed when shooting.

(2) If there is foreground, focus on the scene behind the foreground, and the foreground can be blurred.

(3) How to set the large aperture of the mobile phone: (see the figure below) Turn on the camera of the mobile phone. At the top of the screen, there is an icon similar to a shutter. You can set it with a click.

2. After the shooting is completed, you can retouch the picture through your mobile phone and adjust it to blur:

(1) Open the photo with mobile phone retouching software Snapseed.

(2) If the color is not suitable, use tools to adjust the picture and color it appropriately. Because there is more light in the photo, the highlights are reduced and the light is more obvious.

(3) Blurred: Blurred tools and lenses. There are two circles in the photo which are concentric. When the center of the circle is blue, you can adjust the size of the circle. Hold down two fingers and contract to the middle, so that the inside is small and round, just at the edge of the person.

(4) Finger sliding up and down in the picture: Because the original picture is dark, adjust the vignetting intensity to 0. Transition refers to the extent to which the range between two circles is blurred.

Four methods of shooting "fuzzy" background with mobile phone;

The "blurred photos" mentioned by the landlord should mean "clear subject and slightly blurred background", which can be realized from four aspects: shooting distance, equipment and later stage.

First, control the "distance" between the mobile phone lens and the main body;

When shooting with a mobile phone, the closer the lens is to the subject, the more blurred the foreground or background will be under the premise of clear focus.

While mastering the shooting distance, we should also pay attention to the focus position, which determines the blur position.

1- Left: Focus on "Far Bud" to blur the close-up.

2- Right: Focus on "nearby flowers" and the foreground is blurred.

Second, shoot the blurred background with the help of "external lens":

Similarly, mobile phone photography, we can also use external lenses to enhance the shooting effect.

Connecting a macro with a mobile phone is the same as the "camera close-up" shooting mentioned above, and at the same time, it can further shoot a lot of detailed pictures that are invisible to the naked eye. Of course, the background blur is more obvious.

It should also be noted that when macro shooting, the focus should be accurate, and the mobile phone will focus automatically, but before shooting, you should get used to clicking the focus position repeatedly with your fingers in order to further focus clearly manually.

When shooting some distant scenes, if you use the telephoto lens of your mobile phone, you can not only get a clear distant scene, but also get a good depth of field effect.

Shoot directly with the mobile phone (Figure 1), then use the mobile phone and telephoto lens (Figure 2). In contrast, (Figure 2) the background is blurred obviously.

When shooting with a telephoto lens of a mobile phone, we should pay attention to ensuring the stability of the mobile phone, otherwise it is easy to blur the picture. It is recommended to cooperate with a tripod when you first contact.

Three, use the mobile phone "portrait mode" shooting:

Nowadays, many mobile phones have "portrait shooting" mode, which can imitate the effect of "large aperture", but because it is intelligent blur, it is not real optical imaging, and some details will be blurred.

Comparing the three pictures, although the background of "portrait mode" is blurred obviously, if you carefully observe the surroundings of the subject, there will be the defect of "fuzzy failure". So the partners used it carefully when shooting.

Fourth, the vague background of post-production of mobile phones:

Finally, the post-production of "blurred background" through mobile phones is usually a way to save the background of the picture from being too messy and to remedy it later.

The specific method of making a mobile phone: click "Mobile Party Shooting", then click "Send Private Message", and reply to the keyword "Blacken Background" to receive the relevant method.

The shooting function of mobile phone is essentially the same as that of SLR camera, micro-single camera and card machine, but there are differences in structure and performance. If you want to achieve the same or similar blur effect as a SLR camera, the method used is roughly the same, so the method introduced below is also applicable to other cameras.

The so-called blur means that some elements in the composition picture are not allowed to be clearly presented, but only give a vague, illusory and vague feeling, so that some elements can be more prominent, clear and conspicuous. The essence is to use contrast means to further highlight the subject, express the theme and beautify the picture.

Fuzzy objects are generally fuzzy background, also known as fuzzy background; The future is vague; There is also the ambiguity of the periphery, the ambiguity of special positions and objects. But as far as shooting is concerned, only the background and foreground can be blurred, and other blurring needs to be realized by software later.

For example. If we are facing a steamed stuffed bun with steamed stuffed bun skin outside and meat inside, and the steamed stuffed bun skin is "translucent", we can vaguely see the translucent steamed stuffed bun skin in front and the translucent steamed stuffed bun skin behind, and the meat in the middle is the main body of the picture, and the meat stuffing body is clear and practical. This effect, which is usually called "empty foreground and empty background", will lead readers to focus on watching and appreciating steamed stuffed bun meat, while diluting and ignoring the observation of steamed stuffed bun skin; Is it possible to directly remove the steamed stuffed bun skin? No, because of the existence of steamed stuffed bun skin, it sets off the main body of meat stuffing and plays a role in setting off and comparing.

The task of blurring is to make the steamed stuffed bun look translucent.

How to blur the shooting picture? There are usually the following methods.

First, large aperture shooting. The aperture size not only determines the instantaneous light input of the camera, but also brings the imaging effect of large aperture (small value, such as 4.0, 2.8, etc.). ) and small depth of field; Small aperture and large depth of field. The depth of field is a bit like the longitudinal depth of meat stuffing mentioned above. Our ideal goal is to control the depth of field and the longitudinal depth in the range just before and after the meat stuffing, so that the meat stuffing is clear and the front and back sides of the meat stuffing are "translucent".

The aperture selection range of a mobile phone is similar to that of a camera. Generally, we can control it above 4.0, that is, the aperture is greater than 4.0 and the value is less than 4.0.

How to achieve the above goals with mobile phone shooting? Two ways. One is to use the "professional mode" of camera function to actively set a larger aperture; One is to turn on the "big aperture" function of mobile phone shooting.

If you use the first method, you need to pay attention to the coordination and balance between the aperture value and other parameters such as speed and sensitivity, because a good depth of field (or blur) is only one of the creative goals, and other parameters should also be taken into account. If the second method is adopted, priority will be given to shooting with as large an aperture as possible, and other parameters will be taken care of accordingly; As far as convenience is concerned, it is appropriate to select the "large aperture" function.

Second, shoot away from the background. In the same depth of field, the farther the background is from the subject, the more virtual the background image will be, and vice versa. Therefore, we must pay attention to this when composing and framing.

Fourth, post-software processing. This method mainly solves the problem that the surrounding and specific elements are further blurred.

The above four methods can be used together, and if they are well controlled, the effects of several methods will be superimposed, and an ideal picture will be obtained.

Is there any good way to "blur" photos with mobile phones?

There are two common ways to "blur" photos with mobile phones, one is free, and the other is expensive.

I'll tell you alone.

A "blur" method of shooting with a mobile phone without spending money.

There are two kinds of blur methods that don't cost money to shoot with a mobile phone. The first kind of pre-shooting, the second kind of post-repair.

I will tell you one by one.

1, taken earlier ↓↓↓↓

Blurring the background is actually enlarging the aperture. When the aperture is large, the background will naturally blur when it is deep and shallow. Some mobile phones can set the aperture value, while others can't. What shall we do? You focus on the subject. If you get closer, the subject will be photographed and the background will be photographed.

Now that the mobile APP is so powerful, who doesn't have a few photo retouching apps in their mobile phones?

Then come on! Fix it if you can't shoot it!

I'll just find an old APP——XX Xiu Xiu, and show it to you.
