Have you learned the rare photography skills summarized by photographers?

Basic photography skills P: Program TV: Shutter Priority AV: Aperture Priority M: Manual Auto: Auto SCN: Night Shutter: Shutter is a device that blocks light from hitting the front of the camera. Generally speaking, the longer the shutter time range, the better. Low second is suitable for shooting moving objects. A camera emphasizes that the shutter can reach116000 seconds at the earliest. Aperture: Aperture is a device used to control the amount of light entering the photosensitive surface of the fuselage through the lens. We use the f value to represent the aperture size. The complete series of aperture values are as follows: f 1.0, f 1.4, f2.0, f2.8, f3.2, f3.5, f4.5, f5.0, f5.6, f6.3, f7. 1. The smaller the aperture, the larger the aperture. Exposure compensation: the exposure compensation ranges are -2.0,-1.7,-1.3,-1.0, -0.7, -0.3 and +0.3,+1.0 and+. Generally speaking, the smaller the brightness contrast of the scene, the more accurate the exposure, otherwise the deviation will increase. How to apply? Generally speaking, in a white environment, the luminosity is low and needs to be improved, and vice versa. For example, when the photographed white object looks gray in the photo, increase the exposure. When shooting a snow scene, the background light is particularly strongly reflected by the snow, and the photometric deviation of the camera is large. Increase the exposure, otherwise the snow will turn gray. When shooting a black object, reduce the exposure when you look at it in the photo to make the black more pure. Depth of field: based on the photographer with camera, the distance from the focus to the near allowable circle of dispersion is called the foreground depth of field, and the distance from the focus to the far allowable circle of dispersion is called the back depth of field. The spatial depth that can be seen clearly at the same time is called the imaging spatial depth of the eye, that is, the depth of field. 1, lens aperture: the larger the aperture, the smaller the depth of field; The smaller the aperture, the greater the depth of field; 2. Lens focal length: The longer the lens focal length, the smaller the depth of field; The shorter the focal length, the greater the depth of field; 3. Shooting distance: The farther the distance, the greater the depth of field; The closer the distance, the smaller the depth of field. Aperture priority: Aperture priority is to manually define the size of the aperture, and then use the camera's metering to obtain the corresponding shutter value. Because the aperture directly affects the depth of field, this mode is most widely used in ordinary shooting. When shooting portraits, we usually use a large aperture and a long focal length to blur the background to obtain a shallow depth of field, which can highlight the subject and obtain a faster shutter value, thus improving the stability of hand-held shooting. When taking photos such as scenery, we often use a smaller aperture value, so that the range of depth of field is wider, which can make the distant and nearby scenery clear, which is also applicable when shooting night scenes. Shutter priority: Shutter priority is to obtain aperture value through camera metering when the shutter is defined manually. Shutter priority is mostly used to shoot moving objects, especially sports shooting. For example, it only takes1125 seconds to photograph pedestrians and11000 seconds to photograph falling water droplets. Formal beauty of composition form (1) Jiugongge composition Jiugongge composition, some of which are also called tic-tac-toe composition, actually belongs to a form of golden section. It is to divide the picture into nine blocks on average, and arrange the themes at any point in the four corners of the central block. This composition can present changes and movements, and the picture is full of vitality. (2) Cross-shaped composition Cross-shaped composition is to divide the picture into four parts, that is, draw two lines horizontally and vertically through the center of the picture, and the intersection of the centers is based on the theme. This composition makes the picture more secure, peaceful, solemn and mysterious. (3) Triangular composition Triangular composition, in which the subject in the picture is placed in a triangle or the image itself forms a triangle, produces a sense of stability, but it is unstable when inverted. Can be used for close-up people, close-up and other different scenes of photography. (4) Three-dimensional composition Three-dimensional composition refers to dividing the picture into three parts, and each sub-center can be put together with the main form. This composition is suitable for multi-modality parallel focus subjects. It can also represent large space, small objects, and vice versa. This composition is vivid and concise. It can be used in different scenes such as close range. (5)A-shaped composition A-shaped composition refers to arranging the structure of the picture in an A-shaped form in the picture. A-type composition has a strong sense of stability, upward impact and strong visual orientation. It can express this form of tall natural objects and their own existence. (6)S-shaped composition S-shaped composition gives full play to the aesthetic feeling of the picture, which is first reflected in the aesthetic feeling of the curve. S-shaped composition has strong dynamic effect, which is both dynamic and stable. The far-sighted government film is the best performance theme. Generally speaking, it extends from the lower left corner of the screen to the upper right corner. (7)V-shaped composition V-shaped composition is the most varied composition method. Its main change is the arrangement in the direction, both upside down and horizontal, but in any case, the intersection point must be centripetal. V-shaped dual-purpose can fundamentally change the nature of single use. Positive V-shaped composition is generally used in the foreground, as the frame structure of the foreground, highlighting the main body. (8)C-shaped composition C-shaped composition has the characteristics of curvaceous beauty, can produce changeable visual focus, and the picture is concise and clear. However, when arranging the subject and object, it must be arranged at the C-shaped gap, so that human vision can move to the subject and object with the arc. Mostly used for industrial themes and architectural themes. (9)O-shaped composition is the visual center formed by arranging the subjects on the center of the circle. A circular composition can be composed of an outer circle and an inner circle. The outer ring is a natural solid structure, and the inner ring is a hollow structure such as pipes and steel pipes. If the combination of overlapping inner rings is adopted, the light and shadow perspective effect of multi-circle chain can be produced. If combined with regular curves, the effect will be stronger. (10) Mouth composition Mouth composition, also known as frame composition, is generally used for foreground composition, such as using doors, windows, holes and other frames as the foreground to express the subject and clarify the environment. The characteristics of formal beauty linear composition structure line are: thick line is strong, thin line is delicate; The curve is gentle and the straight line is rigid; Thick line is heavy, thin line is light; The solid line is static and the dotted line is moving. Such as: vertical line, symbolizing strength, solemnity and strength; The horizontal line symbolizes tranquility, broadness and broadness; Diagonal lines symbolize dynamic and unstable feelings. Leading to the distance, the diagonal line shows a depth effect here. Curves symbolize softness, romance and elegance, which will give people a very beautiful feeling. .
