Introduction to the characteristics of push-pull, shake, and other sports
1. The shape characteristics, performance functions and shooting precautions of the push lens
Pushing the lens has a clear main goal, mainly to highlight the subject and details, while introducing the relationship between the overall and local, objective environment and the subject in a shot. This body and details determine the direction of the lens and the final point of the lens. When the lens is pushed to the main body or the details, the range of the view is from large to small. As the secondary part moves out of the picture, the main body or details to be expressed gradually become larger, “forcing†the attention of the audience, and its falling picture. Finally, the subject or detail is placed in a striking visual center position, giving a vivid visual impression. For example, when shooting news, especially conference scenes, it is often the beginning of the panorama, first of all to explain the environment, and then to the important person who is speaking on the podium, which not only explains the environment, but also highlights the subject. Another example is that when the athlete is standing on the podium to receive the prize, it is often pushed into the face of the athlete by the panorama, so that the athletes who are not easy to see and are not obvious in the big scene are excited or happy. Facial expressions and expressions are highlighted and emphasized, and problems can be explained without language.
During the process of pushing, the subject changes from small to large, and the surrounding environment changes from large to small, so there is a continuous advancement montage sentence. The forward-style montage combination is a kind of connection method in which the big scene gradually moves toward the small scene, and the push lens is also a transition from the big scene to the small scene. As the lens is pushed forward, the subject is enlarged from small to large in the picture, and even the picture can be filled. At the same time, the environment around the subject is large to small, and the larger picture space gradually becomes more and more. The smaller, even disappeared "painting." However, it also has the characteristics that the montage combination does not have: since the zoom scene is not a jump interval change, but a continuous transition, thus maintaining the unity and continuity of the picture space and time, eliminating the montage combination The jump and falseness of the time-space transition of the picture, from the big scene to the small scene, the final decline, the lian system of the subject and the environment has unquestionable authenticity and credibility. For example, in the TV documentary "Love for Half a Century", there is a scene about Guo Bulrun and Jin Ruixiu who used to cook dumplings in the kitchen. The picture is that they are preparing for the oil bottle. The close-up of pouring oil into the pot, using the way of pushing the lens, stops the drop on the close-up of the oil bottle mouth, we can see a drop of oil, two drops, and then quickly put away the oil bottle, this lens vividly tells us this For the old relatives who lived in the Forbidden City in the past, today's life is simple and frugal, and it can be said that two drops of oil see life.
Since the push lens makes the picture frame in motion, it directly forms the motion rhythm outside the picture, so the speed of pushing the lens can also affect and adjust the picture rhythm. For example, on a hillside, a cow just ate a sip of grass and chewed it while looking up at the distance. If it was pushed to the head of the cow's head with a slow and steady speed, it gave people a feeling of calmness such as tranquility, quietness and peace. The same is the picture, the same range of decline, if the speed of advancement is sharp and short, it gives a nervous atmosphere. Especially in the rush, the subject is sharply enlarged, and the visual impact of the screen is extremely strong. For example, in the film "Lola Run", Lola's boyfriend was chased and dian in the dian pavilion to ask for help from Rolla. Such a plot, when the lens was quickly pushed into a close-up view of the dian's pavilion by a city's big vision, showing his nervousness, kong horror, anxious to the limit, but also highlighted his loneliness in this big city.
The push lens can also enhance or weaken the sense of movement speed of the moving subject. When we adopt the push for the characters coming in the direction of the camera, the frame of the picture and the characters form a reverse motion, and the picture rushes toward the oncoming characters, two-way movement. So that they met in the middle, the picture effect significantly enhanced the dynamics of this character, as if its movement speed has increased a lot. Conversely, when a person who is far away from the camera lens is pushed, the speed of the character is slowed down due to the same direction movement.
When using the push lens to take pictures, pay attention to the composition of the falling picture should be accurate, the focus should be accurate, the picture should be appropriate, the speed of the lens should be uniform and consistent with the mood and rhythm within the picture.
