Who can tell me what photography is all about? What are the skills?

The essence of photography is to draw pictures with light.

Through the various reflected light of the object, a picture is drawn on CMOS.

Photography can be divided into two categories: composition and lighting.

The so-called composition refers to the choice of elements in this photo, where to put them and how to put them. The composition method is complicated, such as trisection, central spiral, symmetry, diagonal and so on. The logic of composition may be contradictory, such as trisection and symmetry. For example, in the same portrait photography, it is generally advocated to divide the photos into three parts, which is the so-called three parts, but sometimes it is better to put them in the middle of the picture. For example, people walk under dim street lights, or because the background is a symmetrical road, the choice of composition is somewhat similar to the dispute between Confucianism and Taoism in metaphysics. There is nothing better, but in this painting, you prefer that expression.

As for the use of light, it is the performance intensity of each element in the photo. Derived blur (realized by large aperture or telephoto) is essentially the choice of light and shade for each part of the photo. Generally, backlit portraits are an unconventional way to use light. In conventional photos, it is hoped that the subject will protrude. In the case of forward lighting, the brightness of the subject is balanced with that of Beijing, but this photo is moderate. In backlight, the brightness of the subject is forced to brighten by manual focusing and spot metering (or soft light plate). In this case, the hair will generally be brighter, with a feeling of gold plating, which is more prominent.

Basically all skills can be classified as composition and lighting. The above is just a simple example, and the detailed words can't be expressed in a few words.
