What are the common faults of digital cameras?

The principle of digital camera recording images on film by using the chemical changes of silver bromide is different from that of ordinary camera. The sensor of digital camera is photosensitive charge coupled device or complementary metal oxide semiconductor. Let's take a look at the common faults of digital cameras.

Expanding reading: common composition skills of digital cameras

Triangular composition can be divided into horizontal trisection and vertical trisection. It refers to dividing the picture into three equal parts, each of which can be placed in the center of the subject, which is suitable for expressing the subject with multi-form parallel focus. It can represent not only large spaces and small objects, but also small spaces and large objects. Triangular composition is concise and can clearly express the theme, which is one of the composition rules commonly used by photographers. For example, when shooting landscape works with the horizon, in order to avoid the rigidity of the whole picture caused by the horizon in the middle of the picture, the photographer should consider putting the horizon in one third of the picture. When shooting portraits, photographers should also avoid arranging characters in the middle of the picture, and should put them on the three-point line of the picture as much as possible, so that the visual sense will be stronger.

1. Jiugongge composition

Jiugongge composition, also known as tic-tac-toe composition, actually belongs to a form of golden section. Jiugongge composition is to divide the picture into nine blocks on average and arrange the main position at any of the four corners of the central block. In fact, these points are all in line with the "golden section law" and are the best positions in the picture. Jiugongge composition can make the picture change, dynamic and more dynamic. Of course, these four points also have different visual senses. The upper two points are more energetic than the lower one, and the left one is stronger than the right one. But the point is to pay attention to visual balance.

2. A-shaped and triangular composition with strong sense of stability

A-shaped composition refers to arranging the structure of the picture in the form of a word in the picture. A-shaped composition has a strong sense of stability, and the pictures taken by this composition form have upward impact and strong visual guidance. It can be used to express this form of tall natural objects and objects themselves. In the process of shooting, if the subject to be shown is placed at the junction of the top of A, it can play a mandatory visual guidance role.

triangular structure

Triangle is a balanced and stable morphological structure, and photographers can apply it to photographic composition. Triangle composition can be divided into regular triangle composition, inverted triangle composition, irregular triangle composition and multiple triangle composition. Regular triangle composition can create a sense of overall stability of the picture, giving people a powerful and unshakable impression; The inverted triangle composition gives people a sense of tension caused by openness and instability; Irregular triangle composition can give people a feeling of flexible jumping; The composition of multiple triangles can show vivid dynamics, which is more common in shooting valleys, waterfalls and mountains.

In the process of triangle composition, there is another situation in which the triangle situation in the picture is used to highlight the main body. This triangle composition is a way of visual perception, which consists of shapes and shadows. If it is a naturally formed linear structure, the main body can be arranged at the center of the hypotenuse of the triangle at this time, but the effect is best when there is only a panoramic view. In addition, triangle composition can be used for photography of different scenes, that is, it can be used not only for distant and middle scenes, but also for close-up people and close-ups

3. Increase the presence of mouth components.

Mouth composition is also called frame composition. Generally, this composition is mostly used in the foreground, such as using doors, windows, mountain passes, frames, etc. As a way to express the theme and clarify the prospect of the environment. This form of composition is more in line with people's visual experience, and the audience can watch through the door or window, which can produce a stronger sense of realistic space and a certain perspective effect.
