What does the lens push and pull mean?

1, push: push the lens, push the lens, indicating that the subject is not moving and the shooting machine moves forward to shoot. The shooting range changes from large to small, which is divided into fast push, slow push and fierce push, which is essentially different from zoom push.

2. Pull: When the subject is stationary, the lens moves backward, and the field of vision changes from small to large, which can also be divided into slow pull, fast pull and sudden pull.

3. Shake: It means that photography and camera move up and down, left and right, rotate and other actions on the tripod according to the different chassis, so that the audience looks around as if they are standing in the same place.

4, mobile: also known as mobile shooting. Broadly speaking, all kinds of sports shooting methods are mobile shooting. However, in general, mobile photography refers to placing photography and cameras on vehicles and shooting objects while moving along the horizontal plane. The combination of panning and panning can form a panning shooting mode.

5. Follow-up: refers to follow-up shooting. Follow-up is one kind, and there are follow-up, follow-up, follow-up, follow-up and so on. It will be combined with more than 20 shooting methods such as pull-ups, shaking, moving up and down. At the same time. In short, the methods of follow-up are flexible and diverse, so that the audience's eyes are always fixed on the human body and objects being followed.

6, l: up photography, video.

7. Health: Down photography and video.

8, prone: prone shooting, often used to show the overall appearance of the environment.

9. Yang: Yang school often means tall and solemn.

10, Swing: Swing shot, that is, sweeping shot, refers to the sharp change from one subject to another, and as a means of scene change, there is no trace of editing.

1 1, hanging: hanging photography, sometimes including aerial photography. It has a wide range of expressive force.

12. Empty: Also known as empty shooting and scenery shooting, it refers to the pure scenery shooting without the characters (whether people or related animals) in the play.

13, cut: the general term for conversion lens. Any shot clip is a "clip".

14, synthesis: refers to comprehensive shooting, also known as comprehensive lens. It combines several shooting methods such as pushing, pulling, shaking, moving, following, ascending, descending, leaning, leaning, spinning, throwing, hanging and flying into one lens to shoot.

15, short: short lens. Movies generally refer to shots with a duration of 30 seconds (24 frames per second) and a film length of 15 meters; Television is a continuous picture of 30 seconds (25 frames per second) and about 750 frames or less.

16, length: refers to the long lens. Film and television can be defined as a continuous picture of more than 30 seconds.

There is no recognized "scale" for the distinction between long shots and short shots in the world, and the above standards are all general. Hitchcock's The Rope has a long shot of 10 minutes, which is as long as a book (referring to a tin box copy), and a short shot of a war movie, which is as short as two frames, depicting the shadows of fire and guns.

17, counterattack: refers to the camera, which shoots in different directions when shooting a scene of two people. For example, shooting a man and a woman sitting and talking, first shooting the man from one side, then shooting the woman from the other side (close-up, close-up, bust), and finally cross-editing to form a complete clip.

18, zoom shooting: photography, the camera does not move, through the change of lens focal length, people or things in the distance can be clearly seen, and the close-range can also be blurred from clear.

19. subjective shot: also known as subjective shot, that is, the shot that shows the subjective sight and vision of the people in the play often plays the role of visual psychological description.

When shooting rain scenes, we should pay attention to the following points:

1, the light changes greatly in rainy days, sometimes the brightness of rainy scenes is low, and the brightness of rainy days is very low. The exposure between the two.

The amount can be changed many times, so it is best to measure light with an exposure meter when shooting.

2. When shooting in rainy days, overexposure often occurs, which is extremely unfavorable to the performance of rainy scenes. Because the contrast is small in rainy days, overexposure will make the contrast smaller and the photos will look gray. Therefore, the methods of reducing exposure and prolonging development are generally adopted to improve contrast. The normal exposure is reduced by one frame to one frame, and the development time can be increased by 20%-30%.

Extended data shooting technology:

1. Take the long focal length lens as the main shooting lens (about 250mm lens for 120 camera or about 135 lens for135 camera), and take its short depth of field function.

2. According to the principle of portrait formula composition method, close-up, half-length, seven-point or full-body composition can be taken directly, about 5-8 steps away from the subject.

3. During exposure, according to the characteristics of portrait photography, the aperture compensation of 1 ~ 2 should be turned on to make the facial texture brighter. The light on people's faces is soft and bright, which is the focus of this kind of photos.

4. In order to create bright eyes, it is best to place a reflector or whiteboard in front of the portrait to make the eyes reflect bright spots.

5. When printing, it is best to follow the post-processing skills and soft focus treatment to completely soften the skin and make the whole photo soft.

6. You have to change the shape or props of the theme characters, otherwise the visual focus of the photos will remain unchanged, and the shortcomings of composition, depth of field and shooting techniques will be exposed.

7. Design the modeling style of the theme portrait, choose the scene suitable for the overall performance, and do a good job in the preliminary theme and scene design.

8. Usually, we should cultivate the ability of aesthetic composition, and draw up the overall composition plan between the theme portrait and the scene when shooting. Don't fall into the stereotype of portrait formula composition, take close-ups

9. Analyze the application of lighting on the spot, fuse the main body of the portrait to be photographed by addition and subtraction, and control the outstanding performance of lighting in the scene environment without falling into the common problems of general commemorative photos.

10. Control the length of depth of field, create a touching and advanced depth of field performance, and don't fall into the messy mode of ordinary life photos.

1 1. Choose the most suitable photo opportunity to press the shutter, grasp the vitality of the portrait and the artistic sense of the scene, and take a perfect portrait with scenery.

12. The most important thing to take this kind of photo is the choice of negative. As long as the black and white negative is used, the tone of this photo can be printed.

13. In the process of shooting, we should pay attention to the color of the background and props, especially the gray system, because too black and white background, props or clothes will make the photos produce all-black or all-white reaction when they are developed, which is the common sense of shooting black and white photos. Only when the gray scale system is suitable, the single tone of color printing overprint will have rich hierarchical performance.

14. When taking black-and-white photos, you can get beautiful colors by controlling the exposure correctly. Different from the color negative film shooting method commonly used by ordinary portraits, more than two exposures are often used to compensate. Only by correct exposure can we avoid the loss of saturated sound.

15. There is also a film produced by Ilford on the market, which can be directly developed into color without manual development of black and white liquid medicine, and the shooting effect is the same, which is a relatively convenient film.

16. After shooting and developing the negative, you can develop pure black-and-white photos through the black-and-white development process. Or through the printing process of color printing, a single-tone photo is printed.
