Light skills in artistic photography

In daily photography, photographers usually spread the media through light and shadow, and achieve better artistic modeling effect through the combination of light. With the existence of light, photos can easily express the photographer's thoughts and feelings, but also can render the surrounding environment and atmosphere. The following are my lighting skills for artistic photography, hoping to help everyone.

Where there is light, there will be shadows. Using light as a medium to render different shadows under the light, photographic works will present amazing artistic conception and style, just like two similar things, with different lighting effects, the similarity will disappear. When the light and position in the photographic works are isomorphic with the audience's thinking consciousness, the photographic works created will bring people awe and unspeakable mystery.

1 photography art

Photography is an expression of the real art media through the lens, which is also a unique technical feature of photography. From this point of view alone, the photographic medium itself cannot interpret itself. Because of this, this kind of art media has always played a decisive role in our impression of photography. The media contributes to the "authenticity" of photography itself, which is reflected and expressed through photos. In the photos we see every day, the authenticity is obvious. Photograph is an acceptable visual form and the construction of truth. Photographers use photos to interpret the true meaning. At the same time, photography also strongly shows a strong desire to see the truth first. A photograph is a concrete expression of truth in an image. Up to now, photography technology has continued and differentiated in its related fields through various forms. At the same time, photography also has historical, cultural, aesthetic and cognitive connotations. The authenticity of photos is expressed in the form of photography, which shows the audience strange, mutually exclusive or attractive forms-scientific or artistic, highlights or documentary, digital or analog pictures.

The principle of authenticity of photography constitutes the reflexive and referential characteristics of photography itself, and the essential feature of photography, in the words of philosopher Sheila, is that photography lies in the process of generating and spreading the real model of building things. Therefore, the way to explain whether things are true or not will eventually be strengthened in the form of pictures and then spread to the audience. The history of photography is actually the historical accumulation of visibility and authenticity of things. It attempts to combine the objectivity of Talbot's "pen of nature" with the external subjectivity of daily life. Photographs are a true portrayal of recorded history. In the history of photography, photography is not only an interpretation of truth, but also an objective cognitive attitude, which is also the unique charm of photography. Even though the historical era of photographic records has disappeared, the photos recorded at that time can bring a visual reality to future generations.

2 The influence of light on life and shooting

2. 1 Light affects the overall shooting effect.

From a physical point of view, the brightness of the object we see is determined by the light shining on the surface of the object and the reflection ability of the object itself. For example, a black swan hair, although its reflection ability is very weak, if placed in strong light, the brightness value of swan hair will be much higher than that of white paper in weak light. Facts have proved that the subject will show different brightness under different light. It is precisely because of the strong influence of subjective and objective light that the subject will show different results. When shooting, the brightness value will change due to some or minimal factors. Therefore, the brightness value directly affects the overall effect of the subject, and the brightness value is relatively generated.

2.2 Seasonal variation of light in photography

As we all know, the position of the sun changes from sunrise in the morning to sunset in the evening, so the light shining on the object will also change its angle with the movement of the position of the sun. Due to the change of angle, the shadow balance and texture of the object surface will change as a whole because of the movement of light. Generally speaking, the best illumination angle of the subject is about 45 degrees above the subject, and the time period is about 10 ~ 14. Because photometry is also used, the shadows will be different with different angles. High-angle shadows are shorter and low-angle shadows are longer. We must choose the lighting angle carefully, because there is only one lamp a day. This requires photographers to carefully observe and study the subtle changes in different climates, environments, time, directions, seasons and angles, and even the emotional effects of the pictures presented by photographers in the lens, so as to better use light to express ideas and themes.

2.3 Distinguish between soft and hard light

If we distinguish light from light quality, light can be divided into "soft light" and "hard light". The so-called "strong light" refers to direct light, which usually refers to sunlight or artificial light without other objects or clouds, such as flashlights, floodlights and detection lights. Under the irradiation of direct light, the contrast between the shadow part and the light receiving part of the subject is large, the shadow is thick, the bright part is clear, the contrast of the picture is strong, and the three-dimensional sense is strong. On the contrary, for other subjects, such as petals, skin and so on. When the difference between light and shade is too large, it will give people a very rough feeling. When shooting, the flash will generally shoot the photographer's exaggerated shadow, which makes the picture lack of aesthetic feeling and too stiff. The so-called "soft light" is a kind of light that does not produce soft and obvious projection, such as light blocked by clouds or light on cloudy days. The light projected by soft paper or reflected by reflector also belongs to soft light. Because the light is neither direct nor reflected from the same direction to the object, the shadow is light, the contrast is small, and the contrast of colors is soft. Like the sun covered by clouds, cloudy days with high visibility mixed with scattered light are considered as the best "photo day".

2.4 changes in light in the photographer's world

An excellent photographer has a very deep understanding of the requirements and treatment of light. They know the characteristics of light and the effect of light can directly affect the audience's feelings about life. Photographers usually use the combination of light and shadow to create and express the atmosphere of emotional plots in their works, so that the works they create are more tense and expressive. Light brings life and vitality to photos, but also brings infinite charm, giving people a far-reaching poetic mood and a beautiful melody like music. Photographer ansel adams's Thunderstorm in Yosemite Valley has fascinated countless people: dense clouds indicate the coming of a storm, and the scene in the middle is steep hills, rocks and forests, which can't help but remind people of the picture of "a dead vine, a faint crow, a small bridge and a mobile family". What's more, the layers of light and shadow are progressive, further strengthening the gloomy atmosphere before the rainstorm. The close shot is a touch of sunshine on the big fir tree, which constitutes the strongest sound in the magnificent mountain and river music, just like entering a magical realm, with a solemn and magnificent symphony music in my ear. This is the most perfect interpretation and embodiment of Adams' photographic art style, and it is also the result of Adams' lifelong savings and brewing. Adams would often travel long distances over mountains and concentrate on observing the changes in the situation at the top of the mountain and the light and shadow of the jungle in the canyon. These subtle changes are in his eyes, and finally constitute his amazing perfect picture, which is beyond the reach of anyone who lacks creative preparation or even artistic accomplishment.

3 lighting performance of light in photography

Light is a narrow band that the human eye can feel. People usually have no clear boundaries for visible light. Generally speaking, the visible spectrum contains light with a wavelength of 400 mμ ~ 700 mμ, and the human eye can only see colors in the range of 400 mμ ~ 700 mμ, because only a small range of light energy can stimulate the optic nerve in the eye. Because light travels in a straight line, we can see our own shadow when there is a moon on a sunny day or at night. Without light, there is no color. The reason why green peppers turn green in people's eyes under the irradiation of light is because the corresponding wavelength of green peppers is exposed in the light. Therefore, only in the correct shooting, the subject can correctly restore the color, texture and level of the object, and achieve the perfect visual effect in people's eyes, which is also the fundamental requirement for photographers to use light correctly in the shooting process.

Light source plays an important role in the process of object restoration. Due to the difference in performance and color temperature between light and sunlight, the color temperature of light is only 3200 kilowatts, while that of sunlight is 5400 kilowatts. So under the irradiation of sunlight and light, objects will appear in various colors. For example, people see red substances as bright red in the sun, but they are purple in the light. This is because the light source is different, so the degree of color reproduction is different. So the soul of photography is light. Without light, the artistic sense and texture of photography cannot be discussed. Only by facing up to the light, grasping the changes and laws of the light, understanding the artistic effects brought by the light in photography, and finally skillfully using it in photography creation, can you become a handy "good helper" when shooting.

4 the role of light in artistic photography

Li Bai, a poet in the Tang Dynasty, wrote "Until, hold up my cup, I ask the bright moon, bring me my shadow, and make the three of us", which vividly outlines a picture of light and shadow. Li Bai, the bright moon and the shadow make readers "see at a glance" and feel nearby. This artistic conception comes from the loneliness and lofty sentiments of the poet Li Bai, from the background of man, moon and shadow, and from the contrast between the bright moon and the light and shadow of the world.

Light and shadow in the real world are like twins and dancers. They are inseparable and interdependent almost every day. From day to night, from morning to dusk, shadows exist with the existence of light, such as the silhouette of light, the reflection in water, the projection of sunlight, the reflection on the mirror and so on. Where there is light, there is shadow. The performance of light in reality is too realistic, which often forms an absurd imagination and dream in people's minds. In this case, light and shadow become a means of mischief. Light is the culprit, and shadow is an accomplice. Their perfect combination constantly diverts people's attention and disturbs people's correct judgment of real things. At this time, light and shadow have become a feeling in people's hearts and a lonely and detached existence.

Photographer Qi said: "Photographers are actually masters of light and shadow", "Photography itself paints through visual and inner light and shadow". From this, we can easily see the important role of light and shadow in the shooting process. In the world of light and shadow, "putting all your eggs in one basket" is like a different feeling that Venus brought to the world after her broken arm. It is precisely because of Venus' broken arm that it has a different kind of beauty, leaving people with infinity.

5 artistic expression of light in photography creation

The visual image of photography is produced by recording the truth on the two-dimensional plane with the help of the change of light and shadow. Photographers convey their experiences, emotions and ideas through pictures. From the aesthetic field, artistic conception is a symbolic artistic aesthetic experience, and the aesthetic artistic conception is the conscious embodiment of China people's self-aesthetic consciousness, which bears the imprint of history. The practical experience of art proves to us that a series of plastic arts such as photography and painting can create artistic conception. Artistic conception, as an artistic noumenon, has penetrated into various works of art, gradually becoming a unique internal structure and aesthetic implication in art, and has its unique aesthetic concept and creative law in various arts.

Light is an invisible energy, which allows us to see the surrounding forest clearly and make photography a reality. Some light is invisible to the naked eye, and some light can be perceived by human eyes, which are closely related to photography. This light is called "visible light". Light waves of different wavelengths make up different light, and the visible spectrum of each wavelength will present an alternating color. This principle urges us to explore the vision of the outside world. Photographers form their own artistic modeling through light, which determines the expression effect of pictures. Because of the light, photographers have formed different artistic styles.

In fact, the form of light can be controlled by the outside world. For example, in the work "Unsafe Life", a little girl is marked with white spotlights around and inside, representing some evil force. It tells people that what the little girl feels in this gloomy environment is not the longing and happiness of life, but some danger in life. The range that people can see with the naked eye is much wider than that recorded by the camera. The acceptable dynamic range of human visual system is 100000: 1, so that people can see black words on white paper at night and during the day. Only under the illumination of light source will the photosensitive materials used in photography change chemically. Light can not only illuminate the object, but also convey the information of the object being photographed, which plays an important role, just as the shape, color, quantity, volume and light and dark configuration of the object can be vividly expressed through light.

How to use light correctly in photography

In order to play its due role, photosensitive materials must be photographed by light source. In the process of photography, the function of light is not only to illuminate the subject, but also to convey the information of the subject. Therefore, light plays an important role as a medium and a bridge in photography. For example, the volume, quantity, texture, shape, color, spatial depth and shape of the subject, as well as the picture atmosphere, level and sensitive configuration of the subject, can perfectly realize the artistry of the subject through the cooperation of light. Therefore, the photographer can not only observe the light from the appearance of the object, but also skillfully use the light from a deeper artistic conception. When shooting the same object, different angles of light will make the picture very different. Therefore, it is the instinct of every photographer to master the feeling of light and the effect of light and shadow, cultivate the sensitivity to light and shadow, and be good at using it. The artist's skill in depicting lifelike objects depends on his hands. Therefore, light is the soul of photography, the process of photography needs light, and the artistic essence of things also needs light. Only by correctly and skillfully understanding and using light, grasping the changing law of light and its unique artistic effect, and effectively studying and using it in artistic photography creation can we reach the highest state of cherishing light as gold and using light as god.

Light plays a very important role in the expressive force and artistic modeling of artistic photography, and is the soul of photography. Photography technology needs light, and to achieve better artistic effects, light is indispensable. Only by adjusting and making good use of the light. The creativity of photography can achieve better artistic effect. In daily photography, photographers usually use light and shadow to spread the media. Through the combination of light to achieve better artistic modeling effect, with the existence of light, photography can easily express the photographer's thoughts and feelings, and at the same time can render the surrounding environment and atmosphere. Where there is light, there will be shadows. Using the medium of light to render different shadows under the light, photographic works will present amazing artistic conception and style. Just like two similar things, with different light effects, the similarity will disappear. When the light and position in the photographic works are isomorphic with the audience's thinking consciousness, the photographic works created will bring people awe and unspeakable mystery.

The problem of using light in shooting works is flexible and varied. Photography is a combination of light and shadow, and light is the soul of photography. Many excellent feng shui photographers in China not only learned and mastered professional photography skills, but also had high artistic accomplishment before shooting many excellent works. "The creative basis of film and television art is photography technology. The update of photography technology has promoted the change of more innovative ideas, and the change of new ideas has promoted the change of various works of art. Technology and art go hand in hand." We usually say that artistic accomplishment includes skills such as painting, literature, chromatics, optics, etc. Therefore, to understand the true connotation of photography, we must change and contrast light and shade to bring psychological feelings to the audience. Therefore, when shooting works of art, we should not only have clear thinking, but also mobilize the use of light modeling and modeling consciousness to express the objective image in an abstract form, so as to create more excellent and amazing photographic works.
