Day after day, year after year, what is your definition of life?

Photography refers to the process of recording images with some special equipment. Generally, we take photos with mechanical cameras or digital cameras. Sometimes photography is also called photography, that is, the process of exposing the photosensitive medium by using the light reflected by the object. Someone once said an incisive language: the photographer's ability is to transform the fleeting ordinary things in daily life into immortal visual images.

Take pictures, make movies or TV. Zheng Ze's Poem Invited by Photography in Renzi Autumn Temple: "Photography travels in a lifetime, either left or right." The first chapter of Hong Shen's film drama performance: "Drama can't reflect life as accurately as photography does to scenery. Photography is an applied science of photography developed with the formation and development of traditional photography technology. Based on photographic optics, photographic chemistry and electronic technology, it has formed a unique shooting system in long-term practice.

still-life photography

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. It's called still life photography.

Documentary photography

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.

artistic photography

With the development of the times, 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.

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

Generally speaking, people take pictures with visible light, and cameras are the most commonly used. Because of different scenes and uses, cameras have many classifications. Generally speaking, a camera must have several basic components to ensure the exposure process, including: photosensitive medium, imaging lens, exposure time control mechanism, film cassette, storage medium, electronic photoreceptor and electronic storage medium.
