When we see something interesting and want to photograph it, the most basic composition is to focus on the center of the photo. This composition is not bad, but if you want to make the photo more attractive, you can try different composition techniques. One of the most classic composition techniques is the rule of thirds. When you turn on the grid line function, you will see that the camera cuts the top, bottom, left and right of the picture into three equal parts and 4 lines (2 straight and 2 horizontal). Focus on any one of the intersections, and the photo becomes more harmonious and attractive, and looks better than a photo that focuses on the middle.
