What is the sense of hierarchy in photographic photos?

The so-called layering mainly refers to the relationship between light and shade (black, white, gray) of the image and the relationship between the front, middle and long-term perspective.

Level is the abbreviation of tone and tone level. It is the brightness and color level of the scene displayed in the photo. Hierarchy is the basic factor that constitutes an image, and it is an important means to deal with photo modeling and composition to express emotions. There must be at least two levels to form an image. For example, a black-and-white photo has only two levels, while a backlit photo has very rich levels. There is a sense of hierarchy, which requires the color tone (black, white and gray) and color tone level of the picture to be varied and rich.

In addition, the sense of hierarchy also refers to the sense of space. For example, nearby objects are clear, and distant unimportant objects are virtual, which are divided into primary and secondary. Hierarchical, let people know which is close-up and which is long-term. If a photo gives you a very realistic feeling, rich colors and obvious three-dimensional sense, it means that the photo has a very good layering. For example, the close-up of flowers, taken with a small aperture, and the background of flowers are very clear, so the distance between flowers and the background is difficult to distinguish, that is, there is a lack of layering. In other words, if you shoot a large aperture, the background behind the flower is blurred, which is closer to the human eye's vision, highlighting the distance between the flower and the background, and the layering is immediate; If there is only one mountain or clear water in a landscape photo, it is difficult to highlight the magnificent atmosphere of the landscape. If the shooting includes close shot and middle shot, the distant scenery will be set off, and similarly, the sense of hierarchy will come out. Whether a photo is plain, attractive and layered is very important!
