The relationship between the three elements of photography

Do you know what are the three elements of photography? Photography is an instrument to record our life, but how to record every bit of our life beautifully? Let's take a look at the relationship between the three elements of photography. I hope to share more beautiful life.

The relationship between the three elements of photography 1 1. Exposure: exposure refers to the amount of light that enters the lens and shines on the photosensitive element during photography, which is controlled by aperture, shutter and sensitivity. It also means that something is exposed or exposed.

Second, focusing: focusing refers to adjusting the focal length when using the camera, which is called focus in English. Generally, digital cameras have various focusing modes, namely, automatic focusing, manual focusing and various focusing modes.

Third, composition: photographic composition is a "theory" that people sum up from a set of practical experience based on successful photographic works. Photographic composition can help beginners get started quickly.

Equipment used

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.

Photography classification

Still life photography: Compared with portrait photography and landscape photography, it photographs 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. 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.

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.

Portrait photography: 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 primary 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. 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 relationship between the three elements of photography 2 1. Shooting angle: it can be understood as shooting location+viewing angle, and it can also be understood as the photographer's decision on style and way of seeing the world.

2. Shooting process: This refers to the "decisive moment" of the thing itself, which is a collection of photographer's skills and creativity. Specifically, on the one hand, the subject's own conditions determine the shooting opportunity, such as the change of light in landscape photography, the display of smile and eyes in portrait photography; On the other hand, the photographer's skill and creativity also affect the performance of the picture at this moment.

3. Post-production processing: refers to the processing after the photo is taken. Film digital has its own post-production processing method. These processes can be regarded as the expansion and perfection of the photographer's own creativity. These three elements can also be distinguished in chronological order.

Three-element rule of picture effect My own three-element rule: a good photo is determined by one-third of the picture composition, one-third by the lighting effect and one-third by the shooting technology. Composition: a method of arranging picture elements in a picture. There are many concepts here, in addition to the classic composition such as trisection, there are light and shade contrast, tone contrast, line application, negative space and so on. Light effect: Light is the most important shooting condition for photographers. I know it's hard to ask for light for a photographic subject like battlefield documentary photography, but I demand a lot from myself in this respect. Shooting technology: the photographer's shooting technology, including lens focal length, aperture, optimal exposure, post-production processing and so on. It's complicated, but it's essential and must be mastered.
