How many subjects does photography have?

Theme: Still life photography, as opposed to figure photography and landscape photography, takes inanimate, artificially movable or combined objects as the performance object. Mostly take industrial or handmade products, natural inanimate objects and so on as the shooting theme.

On the basis of truly reflecting the inherent characteristics of the subject, the subject is represented as a photographic work with artistic beauty through creative ideas and photography means such as composition, light, tone and color. It's called still life photography.

Still life photography has a vast world in material selection. After selecting materials, we can deal with these objects at will, because objects are inanimate and can move from multiple angles at will to achieve our creative intention.

Still life photography has two advantages: first, the deepening process of further understanding of artistic vision. When some ordinary objects are taken into fascinating photos, it is actually a process of in-depth study and observation of these objects. Secondly, shooting still life can gain more practical photography knowledge.

For photographers, the difficulty of still life photography lies in its unique picture composition. When arranging the subject, we must choose the shooting angle, be creative in using light, and then apply the practical photography knowledge and basic principles learned from still life photography to daily photography.

2. Portrait photography

Subject: Portrait photography is different from ordinary portrait photography. Portrait photography takes the description and expression of the specific appearance and manner of the subject as its main creative task. Although some portrait photography works also contain certain plots, they mainly show the appearance of the subject. Moreover, a considerable number of portrait photography works only illustrate the image of the subject, without specific plot.

Figure photography focuses on the events and activities that the subject participates in, and its main task is to show the specific plot, rather than showing the appearance and behavior of the subject with vivid images. The important difference between them is whether they describe the appearance of the characters in detail.

Whether it's a single person or a group of people, whether it's a snapshot in a scene or a pose in a photo studio, whether it's a plot or not, as long as it's a photo that mainly shows the specific appearance and mental state of the subject, it belongs to the category of portrait photography.

Those photographic works that mainly show the activities and plots of the characters and reflect a certain theme of life, but the appearance of the subject is not very prominent, whether it is close-up or whole body, can only belong to the category of character photography. Of course, in a broad sense, portrait photography is about people and also belongs to character photography.

Portrait photography takes the description and description of the appearance and manner of the subject as its performance task, and the characters should have distinctive looks. Can be divided into three categories: photography indoor portrait, indoor specific environment portrait, outdoor portrait. Portrait photography needs both form and spirit.

Step 3 record photography

Subject matter: Documentary photography refers to photo photography that takes recording as the first purpose and reflects the true image of objective things.

Photography was born for recording. Its powerful vitality after its birth lies precisely in its recording function. This is incomparable or irreplaceable by other technologies or arts. So, broadly speaking, photography is recording. The result of recording photography is an image recording work.

Accordingly, video works include video news works and video documentary works. The purpose of recording photography (perhaps not the only one, but it is the primary purpose) lies in recording; The premise is to respect the objective truth; Object is the representation of objective things; The recording method is to reproduce the image by photography. Recording photography can be divided into news photography and documentary photography according to the different ways of recording images and the different values pursued.

4. Artistic photography

Theme: With the development, people continue to add artistic elements to photography and begin to produce artistic photography. The difference between it and documentary photography lies in the artistic level, but there is no absolute boundary.

For example, let's take a photo as an ID card or leave a souvenir. Generally, the photos taken by the photo studio have at most some information or record value. However, 50 years later, Mr. Zheng Jingkang's portrait of Mr. Qi Baishi is still one of the 20 best portraits in the world.

The difference lies entirely in the artistic level. The effect of artistic photography is more beautiful, because it requires not only technology, but also the time, place and angle of shooting.

5. Photo photography

Theme: Photo photography has always been an important form of portrait photography with its beautiful picture language and beautiful design connotation.

/kloc-In the second half of the 9th century, British photographer Randa filmed a work predicted as "a new era of photography is coming"-"Two Roads of Life". When photography was still despised at that time, this work was highly praised by Queen Victoria for its inspiring theme and oil painting composition.

It can be said that Lanzhou University has contributed a lot to the development of photography. Since then, photo photography has gradually become an important genre of photography.

6. Commercial photography

Subject: Commercial photography, as its name implies, refers to photography activities for commercial purposes. In a narrow sense, it is commercial photography, and in a broad sense, it is a type of photography that publishes goods or writes stories. This type is an extremely important one in current photography activities. This kind of photography exists for commercial interests, and shooting according to the requirements of enterprises is relatively restrictive.

7. Ink photography

Like traditional ink painting, ink photography works appearing on the market now can be divided into landscapes, flowers and birds, and artistic conception according to the subject matter, which corresponds to landscape painting and flower-and-bird painting in Chinese painting; According to the technique and artistic conception, it can be divided into abstract and concrete, which corresponds to the freehand brushwork and meticulous painting of Chinese painting.

Although it is inevitable to use Photoshop and other software to post-process the ink-wash photos, this does not mean that the original photos can be distorted at will. Good ink and wash photography works should modify the original photos as little as possible, which tests the photographer's composition and ability to capture light and shadow.

8. Holography

Subject: Holography refers to a new photography technology, which records all the information of the amplitude and phase of the reflected wave of the object being photographed.

Ordinary photography records the strong light distribution on the surface of the object, but it can't record the phase information of the reflected light of the object, so it loses its three-dimensional sense. Holography uses laser as the illumination source, and divides the light emitted by the light source into two beams, one of which is directly directed at the photosensitive plate, and the other is reflected by the subject and then directed at the photosensitive plate.

When the human eye directly looks at this photosensitive film, it can only see interference fringes like fingerprints, but if it is irradiated by laser, the human eye can see the three-dimensional image of the original object through the film. Even if only a small part of the holographic image remains, it can still reproduce the whole scene.

Holography can be applied to nondestructive testing, ultrasonic holography, holographic microscope, holographic storage, holographic film and television and many other aspects in industry.
