1, the size of the mobile phone image sensor determines that the image quality cannot be compared with that of the camera, so it is best to shoot under the best lighting conditions;

2. The volume and aperture size of the mobile phone lens determine that the depth of field effect can't be compared with that of the camera, so it is necessary to avoid heavy composition;

3. The rich ecosystem of the mobile phone system determines the biggest advantage of the mobile phone-instant sharing, rich and powerful late stage, so we should make more use of late software to make up for the shortcomings of the mobile phone image quality;

4. The interactive mode of mobile phone and the viewing mode of social software determine that the vertical composition shooting method is the best.

5. Post-depth-of-field algorithm, beauty effect, and how to repair net red face with Mito Xiu Xiu are not discussed in this paper.

Line composition

Include guide line patterning, symmetric patter

Use the guide line of spiral stairs to attract the audience's visual center of gravity. The skill of shooting is to put the lines of spiral stairs on the edge of the composition, and naturally you can get a picture of lead wire composition.

As the name implies, the subject is placed in the middle of the picture. This composition is very suitable for regular photos showing the main structure, and the balance of the picture can be just right by using the symmetrical composition rule.

Scenes using this composition method are mostly used to express nature. In this kind of shooting, we often use vertical composition mode, which is also mentioned in the premise at the beginning of the article. We try to make use of the sky to occupy two-thirds of the composition and keep it horizontal to ensure the balance of the center of gravity of the picture, so that we can get one-third of the composition photos, one-third of which emphasizes that the ground occupies one-third.

Square combination (1: 1 combination)

Square composition is the easiest composition method to master. It was first born in the 120 medium format 6X6 camera in the film age, and the original camera in iPhone also has this composition mode. One advantage of using this composition mode is that at present, the preview mode of many social software pictures is 1: 1, so if you take a picture with a square composition, the published effect will be the preview effect of others, which is very helpful for basin friends who often wander in social circles.

Square composition is a bit similar to the symmetrical composition mentioned above, because the frame of the photo itself is 1: 1, so symmetrical composition is the most suitable way to express the subject, which is common to buildings, objects and portraits.

It is no exaggeration to say that 60% of the photos in my mobile phone are composed of squares, because then you can take photos by picking up your mobile phone without thinking too much about composition. It is most stable for beginners to learn to master block composition first, and then gradually master other composition methods. After mastering the square composition skillfully, you can also use some simple skills, such as multiple exposure and mirror composition in the above case, to add a life to the mediocre picture.

Other situations using square composition are not described one by one.

Take portraits in the simplest and cleanest way.

When fans hold up their cameras to take portraits, they will say that the aperture is large and there is no brain blur, so this article will not discuss the depth of field. After all, the current mobile phone can't create the same shallow depth of field effect as the camera lens in physics, and the following algorithm will not be discussed in this paper, so what I want to emphasize is how to take a beautiful portrait with the mobile phone when it is difficult to distinguish between true and false.

The first way is to focus on the environment and highlight the light and shadow effect.

The weather is good, the light is transparent, and the light ratio is large. While ensuring the image quality of the mobile phone, it can also create a light and shadow atmosphere. Photos like this were taken with iPhone 7Plus in an abandoned factory. The weather in the afternoon is fine, and the sunlight shines into the dusty factory building through the window, which naturally forms the Tindal effect, so taking a silhouette against the light at this time has a different texture.

In exchange for an extremely simple and clean picture, it is suitable for depicting big scenes and nature. In addition, it can also highlight the human posture in the details of the building in the architectural scene with structural rules.

The style of iPhone has always been very real. Although the white balance is warm, the details of image quality are still very rich, and there is a lot of room in the later stage. To solve this problem, what we need to do later is to greatly adjust the exposure and contrast to make the picture look cleaner.
