To learn photography, you must first answer a question. What is photography? What is the art of photography? Photography is a combination of light and shadow, a painting of light, a combination of technology and visual observation, and a combination of technology and art. Photography is a conscious, thoughtful, thoughtful and exquisite work of art.

Baidu Encyclopedia's explanation of photography is that the word photography comes from Greek, which means "painting with light". Photography refers to the process of recording images with some special equipment, that is, the process of exposing photosensitive media through the light emitted or reflected by objects. This definition must have been summed up by a science and engineering man, because he explained the technical principle of photography from the perspective of science and technology, but ignored the artistic characteristics of the content of photographic works.

Photography is a kind of instantaneous art and also a kind of visual art. Photography is a modern plastic art that combines science and technology with art. It is a visual art style that photographers use cameras as creative tools, use photography techniques and skills according to their own creative ideas, and take pictures of people or scenery according to the aesthetic laws and characteristics of photography, and then post-process them in darkroom or software, thus creating visual artistic images, reflecting human social life and natural phenomena, and expressing the author's emotions, emotions and thoughts. It is also the visual artistic style that artists refine and refine social life.

The art of photography expresses the image in real life, which has the characteristics of directness, truthfulness, concreteness, vividness and distinctiveness, and makes people know and be infected from photographic works. This is the specialty and advantage of photography. Photography has the following aesthetic characteristics:

Documentary is the unique essential feature of photography, and it is also the independent basis that distinguishes it from other plastic arts. Calligraphy, painting, sculpture, architecture and other art forms can't record people or scenery in a short time, only photography can. A large number of photographic works that we come into contact with in our life are mainly characterized by documentary.

A black-and-white photo, in which a little girl is holding a pencil and looking at the front with big eyes ... This photo named "I want to read" has promoted the development of Project Hope and changed the fate of millions of children from poor families.

Everything in the world is constantly developing, changing and moving, and photography can only shoot a fragment, a detail and an instant in the process of things' development and movement. Real life is rich and colorful, changing rapidly, many precious moments can be met but not sought, and opportunities are fleeting, so creative opportunities are very important. Whether a work is successful or not, immediate discovery and grabbing play a decisive role.

Henri cartier bresson, the "father of modern news photography", founded the theory of "decisive moment". Especially through snapshots, in a very short fraction of a second, the decisive things are summarized and expressed with powerful visual composition. In photography, the smallest thing can also be a great theme. Bresson put forward the most famous "decisive moment" in the history of photography. He believes that everything in the world has its decisive moment. He captures the moment of ordinary life with the photographic style of decisive moment, grasps the appearance and connotation of things in a very short time and makes them eternal.

Bresson inadvertently captured this photo in Monroe, and from this moment of solidification, people saw Monroe's natural beauty and refined demeanor.

This photo is a representative work of Bresson's snapshot art. The figure of the jumping man in the foreground is just similar to the figure of the jumping girl in the poster advertisement behind him, echoing each other and setting each other off. This shooting moment is also a "decisive moment" in Bresson's mind.

The Boy (1958) is a famous work by Bresson. A boy walked home with a big bottle in each hand, as if he had completed a glorious and arduous task. The characters in the photo have very natural and true feelings.

In the process of its own development, photography constantly draws lessons from other plastic arts and gradually forms its own unique plastic forms and typical methods. Photographers refer to their artistic ideas, images shot with high photographic modeling skills, and pictures (photos) made through a series of darkroom production (film photography period) or digital post-processing (digital photography period) as "photographic works of art".

Composition, light and tone are the three main modeling methods of photography. They give people a rich sense of form, such as space, three-dimensional sense, texture, movement, rhythm and so on.

Composition is the first step in the success or failure of photography, in order to express the theme of the photo, arrange the people or things on the screen, as well as their companions and environment, and finally achieve the purpose of highlighting the theme. Common composition methods include nine-grid composition, horizontal composition, frame composition, diagonal composition, curve composition, trisection composition and so on.

Jiugongge composition divides the picture into nine blocks with three lines, and the four points on the central block are the golden points of the picture, which will make the picture more perfect when arranging the main body.

Horizontal line composition. The horizontal line symbolizes tranquility, broadness and broadness, which can produce the same feeling in the picture. Sea level and horizon are obvious horizontal lines.

Frame composition is to frame the subject with objects in the foreground, which can not only give the photo a sense of depth, but also help to highlight the subject.

Diagonal composition can express movement, strength and direction, and usually has a strong sense of movement and symmetry.

Curve composition is usually beautiful, romantic, elegant and changeable, and the viewer's eyes are easily attracted by this line, resulting in unexpected ringtones. It is very suitable for human body photography and landscape photography with curve characteristics.

Triangular composition refers to dividing the picture into three parts horizontally or vertically, and the main body is located on the bisector, which has the advantage of concise composition.

Light and shadow are the soul of photography. Whether it is natural light or artificial light, mastering their characteristics is a compulsory course to control light. Light has four main characteristics: color temperature, direction, quality and contrast.

Color temperature is mainly used to distinguish the colors of light sources. In a clear and cloudless sky, in the absence of direct sunlight, the standard sunlight is about 5200~5500K, the color of incandescent lamp is warm white, and its color temperature is 2700K, while that of daylight fluorescent lamp is 6000 K..

When shooting in natural light, because the color temperature of light is different in different time periods, the color of the photos taken is also different. For example, when shooting under a clear blue sky, the color temperature of the light is high, and the photo is cold; But if you shoot at dusk, the color temperature of the light is low, so the photo is warmer. When shooting with artificial light, there are also different types of light sources, and the colors of the photos taken are different.

The direction of light. According to the position of the light and the shooting object, the direction of the light can be divided into forward light, backward light, oblique light, semi-backward light, top light, bottom light and so on. Only on the basis of understanding and familiarity can we skillfully and accurately use these light positions.

1. Fairness: the illumination direction of light is consistent with the shooting direction of the camera. The color saturation of the scene is good, the picture is transparent and the color is bright. However, there is a lack of three-dimensional sense and shaping sense, so different depth of field can be used to deal with the reality of the picture and highlight the layering of the main scene.

2. Backlight: The illumination direction of light is opposite to the shooting direction of the camera. The edge of the scene has obvious light outline, and the picture has obvious contrast between light and dark, thus producing silhouette effect. But the subject will lose details because of underexposure. Try to use a hood or sun hat when shooting to prevent the lens from entering the light.

3. Oblique light: The irradiation direction of light forms an included angle of 45 degrees with the shooting direction of the camera. Oblique light is a kind of light widely used in landscape photography. The light receiving surface forms a bright part, and the backlight surface forms a shadow part. This kind of light is very suitable for expressing the layering and three-dimensional sense of the scene.

The quality of light. It depends on the size of the light source and the distance to shoot the object. Small light sources cast shadows with clear edges behind objects, and large luminous bodies cast soft shadows. When it is far enough away from the object, it becomes a point light source. According to this feature, light can be divided into hard light and soft light.

Different light qualities have different physical characteristics, which also endow light with emotion. Strong light increases the contrast between the backlight surface and the light receiving surface, and the contrast between light and dark is strong, highlighting the outline of the subject. The light of hard light is more concentrated, the transition is fast, and the contrast is strong, which is suitable for strong pictures and for showing the strength and rigidity of men; Soft light is soft, the main body has no obvious light receiving surface, backlight surface and projection, and the soft light picture is delicate, which is suitable for expressing women's femininity.

Contrast of light is also called contrast. Generally speaking, in photography, the light reception ratio of the dark part and the bright part of the photographed scene. In photography, it is the contrast between light and shade of the picture. If the contrast is large, the visual tension of the picture is strong; Small contrast is soft and gentle. What many photographers call hard tone is Gao Fancha, and soft tone is low contrast.

The light ratio control of landscape photography can only wait for time or weather, adjust the shooting angle or change the light ratio through gradient filter. But in portrait photography, manual intervention is often used to control the light ratio. In outdoor portrait photography, the light ratio can be reduced by the reflector, or improved by the absorber (black).

Tone refers to the light and shade of a photo. Most of the light-colored parts of the photos are high-profile. The overall photo is dark, and photos with more dark parts are relatively low-key. Normal photos that are not bright or dark are all in the middle tone.

Tone refers to the color components of the whole image, and which color is emphasized is that tone. Tone is easy to be emotional. Just like China Red, it is a positive color in China people's emotional philosophy. Tones are divided into cool tones and warm tones, red, orange and yellow are warm tones, blue is cool tones, and black, purple, green and white are intermediate tones.

Since the birth of photography, science and technology have been the basic elements of the development of photography. The history of photography is the history of the parallel development of technology and art, and other art forms are not so strongly dependent on science and technology. For example, in the field of music and fine arts, erhu musical instruments were shaped in the Tang Dynasty, and had quite high playing skills in the Northern Song Dynasty. After the invention of paper in Han Dynasty, painters painted on paper with a brush, which gradually evolved into the present Chinese painting.

Since Daguerre's silver plate photography, from wet plate to dry plate, from black and white to color, from silver salt film to digital, from SLR to non-reverse, every technological innovation has brought convenience and change to photographers' creation. With the development of software technology and AI intelligent computing technology, the photography function of mobile phones will be more advanced and intelligent in the future, and the only limitation is the photographer's imagination.

I hope everyone can take wonderful photos with their mobile phones.
