Master these 6 skills, the mobile phone can also freely control the depth of field and take moving photos

The so-called depth of field, in layman's terms, is the clear range before and after the subject in the photo. For example, in the photo above, most of the elements from the foreground to the background are clear, which is the large depth of field. In the picture below, only the subject's flowers are clear, which is a small depth of field. Depth of field has a very important influence on the visual effect of photos. By understanding its principle and mastering its rules, you can use depth of field as a creative element in photography activities and control its imaging characteristics to achieve a certain visual effect.

1. Controlling the depth of field through the aperture

The aperture of most mobile phone lenses is fixed, and the so-called aperture adjustment is done through the camera It is simulated by the internal algorithm, but it can also achieve the effect of controlling the depth of field. The larger the aperture, the smaller the depth of field, and the smaller the aperture, the larger the depth of field. For example, on a Huawei mobile phone, open the camera, select "large aperture", and click the icon indicated by the arrow in the figure below, an adjustment slider will appear, and the aperture value can be adjusted between f0.91-f16. It should be noted that the smaller the f-number, the larger the aperture, and the larger the f-number, the smaller the aperture. The iPhone can control the size of the aperture through the portrait mode (below). After turning on the camera, select portrait mode, click "f" in the upper left corner, a scale will appear next to the shutter button on the right, and you can adjust the aperture value within the range of f1.4-f16 by sliding it up and down. In addition, for photos taken in portrait mode, the f-number can be readjusted when using this camera for post-editing. The picture below is the effect of shooting in portrait mode. Another point to note is that no matter what brand of mobile phone, after all, it is the aperture effect simulated by the algorithm, so try to control the subject within 2.5 meters to achieve better results. In addition, the greater the contrast between the subject and the background, the more accurate the algorithm's recognition will be, and the more natural the effect will be.

2. Control the depth of field through the camera distance

The so-called camera distance is the distance between the lens and the subject. The closer the camera distance, the smaller the depth of field, and the farther the camera distance, the greater the depth of field. The picture below is the effect of taking the phone close to the flower. Some mobile phones also have the function of macro shooting, of course, it can also be achieved by configuring an external macro lens. The picture below is the effect of the macro lens, because the shooting distance is closer (2-8 cm), the depth of field will naturally be smaller. The picture below was taken with the microscope lens of OPPO Find x3. Because the camera distance is as close as a few millimeters, the depth of field becomes smaller. By the way, this photo is a close-up of a butterfly's wing.

3. Control the depth of field through the distance between the subject and the background

The previous item said the distance between the lens and the subject, here it says Say the distance from the subject to the background. The further the subject is from the background, the smaller the depth of field will be.

4. Control the depth of field through the focal length of the lens

The longer the focal length of the lens, the smaller the depth of field, and the shorter the focal length, the greater the depth of field. With a telephoto lens, you can take a small depth of field effect with a blurred background. In the picture above, I attached a telephoto lens to the phone, and the picture below is the result. Of course, if your phone itself has a telephoto lens, you can, but try not to use digital zoom.

5. Combined use

If conditions permit, the lens should be as close to the subject as possible, and the subject should be as far away as possible Background, in this way, the small depth of field effect of background blur can be more significant. Even if you use a telephoto lens or a large aperture (/portrait mode), you must combine the distance control to get the most prominent small depth of field effect.

6. Using the principle that the depth of field is longer than the depth of the foreground

In photography practice, photographers should make full use of the characteristics of depth of field , Back depth of field, generally can make full use of the depth of field through focus selection. For example, when shooting a close-up of a half-profile portrait, you need to focus on the eyes close to the lens. Because the back depth of field accounts for 2/3 and the foreground depth accounts for 1/3, the near eye is clear, and the other eye will be relatively clear. If you focus on the eye farther from the lens, the eye close to the lens may be out of the depth of field, and it will appear very blurred, which will waste the depth of field. You can compare the effect of the two photos above. The same is true. When taking group photos of the front and rear four rows, the focus should be selected on the second row, so that the full depth of field can be used, so that everyone can be relatively clear in the photo. It's not that a photo with a smaller depth of field is a good photo, you have to be flexible and control it according to your needs. The blurring of the background should be just right, neither so blurry that people cannot understand its specific connotation, nor clear enough to cause visual disturbance to the subject.
