1 The cognitive function of photography.

The instantaneous documentary nature of photography enables his works to reproduce social life in a real image, reflecting the essence of the times and the ideological sense of the characters.

Love, expand people's life horizons. Many landscape photographs reflect famous rivers, mountains, historic sites, cemeteries, and related tourist attractions.

Natural and cultural landscapes.

and photographic works on folklore themes to help people understand the customs and natural environment of different regions.

And. Lifestyle customs. The main purpose of the modern advertising art site is to promote the product intuitively and make people have more about the product.

Specific understanding. The cognitive function of photographic works of art is mainly to help people understand the things reflected and life through the works.

step to improve people's ability to understand real life.

2 Educational features of photography.

Photographic artworks not only accurately reflect the objective real life, but also reflect the photographer's attitude and evaluation of life. When we.

When appreciating photographic artworks, they will also be imperceptibly influenced and educated by the author's tendencies and attitudes.

The educational function of photographic works of art is in a dialectical unity relationship with the aesthetic function and entertainment function, which is what people often call "edutainment."

Yu Le". The educational function of photographic art is not to educate in the form of ear and face, but to be educated in aesthetic appreciation. In a sense.

Above speaking, aesthetics itself is also education, that is, aesthetic education.

3 The aesthetic function of photography.

Photographic works of art can give people a sense of beauty and aesthetic pleasure. Without beauty, there is no art of photography. In terms of content, photography.

The product reflects the photographer's aesthetic evaluation of life and the life itself with aesthetic value and essential significance. In form, photography.

The work expresses an artistic image that conforms to the laws of beauty, meets people's aesthetic needs and can give people a sense of beauty.

Beauty is not abstract, beauty is linked to truth, and there is no beauty without truth. It's really not all beautiful, but it's really the foundation of beauty.

Beauty and goodness are also linked. The image of beauty is always reflected in the photographer's moral concept and social ideals. For this reason, excellent photography.

Cinematic art is always a combination of truth, goodness, and beauty. Without true and good works, there is no beauty to speak of; There is no beauty, photography.

The work loses its artistic appeal.

The aesthetic function of photography is universal. In some works, the cognitive or educational role may be more prominent, while some works.

The aesthetic role of the product is more prominent. Of course, those works that can integrate the three roles of cognition, education and aesthetics are more reasonable.

I want to work. This is the pursuit of photography companies, and of course profit is the main thing.

Answer: The role of photography: 1. Recording facts with images is its main function.

2. Beautiful photographic works give people a happy mood and bring beauty enjoyment. 3. ** (excluding the later splicing manual processing**) as the original factual evidence, it is given a specific meaning by law. 4. ** (excluding the later splicing manual processing**) is a witness to history.

Photography is not only an art, but also a technique, and a vehicle for conveying and sharing information.

The meaning of photography, simply put, is to record history, let history freeze in a moment, and make the moment eternal. From the day it was born, photography has given it the mission of recording. Recording landscapes, current affairs, relatives, and life, for people who like photography, the meaning of photography is to shoot beautiful things to share with everyone and make life better.

Typical portraits are shot with a DSLR camera, and the lenses used (i.e., the focal lengths of the lenses you mentioned) are usually between 70mm and 200mm, or even professional prime portrait lenses. These lenses are of high quality and most of them have large apertures. In addition, people's shooting conditions and photographic accessories, rigorous metering and depth of field**, etc., are all professional requirements ......Therefore, it may be difficult for us to shoot the same effect due to the limitations of many factors.

Or try a bust or a close-up if you try to use the portrait mode on your camera, and try a bust or close-up if possible. If the scenery behind the character is possible, try to stay away from the back of the character, and keep the distance so that the background is out of focus as much as possible.

In addition, if you choose a telephoto (i.e., the greater the optical zoom factor of your camera), your relative maximum aperture will be smaller (because it is not a constant lens), so it will not be conducive to the appearance of short depth of field, and it is not conducive to blurring the background, so it is more difficult to shoot that effect.

But you can't use macro mode to shoot portraits, otherwise the ** that comes out is almost unsuccessful for portrait photography. Of course, if you want to close-up the freckles and sweat pores on the other person's face, it is excepted. Because the focus range of macro mode is generally about 2 to 10 cm (for DC cameras), and we are generally shooting portraits are unlikely to bring the machine in front of others, if the camera is slightly farther away, it will come out of a blur, a work without a clear point, no distinction between the background of the subject, all out of focus and blurred, that is a waste film.

The role of photography is to bring you joy.

Photography is a very happy process, when you get up early before dawn in order to shoot the sunrise, after climbing and trekking to wait for the sunrise, when the sun comes out the moment you press the shutter, all the hard work before will disappear, photography can also change the way of looking at things.

Logical definition of the art of photography:

1. Photography is a typical definition of traditional existential logic, which is given from the principle that photography is a process that goes through layers of separation, first of all, the dichotomy between process and result, photography occupies the process, then the dichotomy between plane and three-dimensional, photography occupies the plane, then the real scene and the virtual thing, photography occupies the real thing, and then the optical principle and sensory impression, and photography occupies the optical principle.

2. After this process of continuous separation of species, the definition of photography is derived. If the separation is occupied by the opposite side of the mind, another definition may be such a face: xx is the process of making virtual objects appear or reflected in the plane from the sensory impression, and the xx in this definition can logically be called painting.

Hello dear. The role of photography: Photography is first and foremost a skill, but also an art, and the subject can leave a lot of precious and beautiful memories.

Photographers can also exercise good aesthetic ability, and when observing the beauty in life, they will be more sensitive and meticulous. The joy of photography lies in the pleasure of body and mind, and in the resonance between the subject and the mind. Feeling the beauty of life, the beauty of detail, and then improving one's aesthetic and artistic temperament, will make people more calm, immersed in the beautiful life, capture beauty, capture memory.

2. Cultural exchanges.

Between regions, between nations, between countries, and between countries, economic exchanges between cultures are needed, so there is a saying that culture sets up a stage and economy and trade sings. Photography, using the cultural landscape and customs presented by the works, as well as the visual effects conveyed through artistic means, gives people a good impression, so as to bring people closer, so photography has a powerful cultural exchange function.

3. Economic development.

Basics of Photography:

The larger the aperture (the smaller the number), the more light will enter and the brighter it will be, on the other hand, the wider the aperture has a shallower depth of field and a more dreamy background for shooting portraits. The smaller the aperture (the larger the number), the less light will enter, the ** will be darker, the background will be clearer with a small aperture, and the scenery will be guaranteed to capture the whole picture.

The higher the shutter speed, the more you will be able to freeze the fast action and capture the effect of solidification. The lower the shutter speed, the less sharp the captured action will be, and the more hazy the subject will be with long exposures. <>

Briefly describe the main functions and functions of the camera?

1. The main components of the camera include: imaging element, anechoic chamber, imaging medium and imaging control structure. Imaging elements can be imaging.

It is usually a lens set made of optical glass, which is called a lens in imitation. Small holes, solenoid coils, etc., all play the role of "lenses" on specific equipment. The imaging medium is responsible for capturing and recording key images.

2. Hello! After the lens light is focused on the film, the photosensitive agent on the film changes with the light, and the photosensitive agent film is imaged by the developer liquid, I hope it will help you, hope.

3. The camera structure includes: imaging element, anechoic chamber, imaging medium and imaging control structure.

The usefulness of the camera.

The purpose of the camera is that for those who like to take pictures, they can record their favorite scenery as an appreciation. For a painter, the camera is inseparable from the body to shoot good works and good words. Admire.

A camera is an optical device used in photography that uses the principle of optical imaging to form an image and record images with a negative. In modern social life, there are many devices that can record images, and they all have the characteristics of cameras, such as medical imaging equipment, astronomical observation equipment, etc.

Camera. The function is to undertake the optical image, and the image into the corresponding data (the digital camera is an electronic sensor to convert the optical image into electronic data, the film camera is the film sensitive) imaging components.

The camera structure includes: imaging element, anechoic chamber, imaging medium and imaging control structure.

The optical part of the camera is mainly composed of a lens, an aperture, a shutter, and an image sensor. The role of the lens is to imaging, the combination of aperture and shutter is used to control the time, and the image sensor is to convert the image composed of light into an electrical signal (in digital machines).

The viewfinder of modern cameras also has a range measurement and focusing function. In order to adapt to different light and dark subjects, in order to obtain the correct amount of light on the film, the length of time and the intensity of the light entering the lens must be controlled.

The optical part of the camera is mainly composed of a lens, an aperture, a shutter, and an image sensor. The role of the lens is to imaging, the combination of aperture and shutter is used to control the time, and the image sensor is to convert the image composed of light into an electrical signal (in digital machines).

The camera consists of a lens, a photosensitive material, and a control mechanism. The image processing system mainly refers to the data conversion and storage system of the camera, covering hardware and software. The lens part, including the lens group and barrel, as well as the drive motor inside the lens, also includes the aperture system.
