It's not always accidental to take a good photo. Some rules can help you take an unusual photo, and the rule of dividing the country into three parts is the most effective.
(Try to put the main interest point of the photo at or near the intersection of one of the horizontal lines and the vertical line, so that the photo taken is beautiful and dynamic)
Imagine a grid on your photo, in which two lines horizontally divide the photo into three equal parts, while the other two lines vertically divide the photo into three equal parts. Now, put the subject at the intersection of one of the horizontal and vertical lines. Then put the horizon on one of the horizontal lines-that's the rule of composition by trisection. Just put the key picture factors into rules. As long as the key factors are placed at these intersections, almost all of them can get a strong composition.
(If the subject is vertical, place it in the left or right third of the picture. If you are shooting portraits, the position of your eyes is best on one of the horizontal lines. )
Of course, some digital camera users don't have to imagine it out of thin air like this, they can put the rule grid of trisection on the display screen when composing a picture.
(Putting the horizon on one of the three horizontal lines can create a more balanced composition. )
We tend to put the subject in the middle of the photo, or put the horizon on the center line of the picture when shooting scenery. It can't be said that this is wrong, but such a composition is difficult to attract people's attention. If you move the subject away from the center or move the horizon up or down, your photo will be full of vitality immediately.
(Of course, any rule can be broken, and some photos can't simply apply the rule of three-point composition. )
Note:
1. There are many rules to follow, so it is not necessary to stick to this one. If you think your photos will be better composed in a slightly different way.
2. In order to better understand the composition rules of the trichotomy, you can observe some photos you like and imagine putting a grid on them.
3. Sometimes you can cut your photos (use software such as lightroom, photoshop) to make a composition, which is more in line with the rule of three-point composition.
