Photography is divided into several categories, each with its own characteristics.

Still life photography, as opposed to figure photography and landscape photography, takes pictures of inanimate objects (this concept of inanimate objects is relative, such as fish and shrimp caught from the sea, melons and fruits picked, etc. ) and man-made objects that can move or combine freely as performance objects.

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.

2. Portrait 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.

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 still mainly show the appearance of the subject, and a considerable number of portrait photography works only explain the image of the subject without specific plots.

Step 3 record photography

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

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

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, which requires not only technology, but also the time, place and angle of shooting.

5. Photo photography

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

6. Commercial photography

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 brushwork 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 need to modify the original photos as little as possible, which tests the photographer's composition and ability to capture light and shadow.

8. Holography

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. 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.
