There are several ways to push in photography, and what are their characteristics?

First, the camera shoots forward along its optical axis, and the obtained picture effect is that the unified object changes from small to large, the viewpoint moves forward, and the viewpoint remains unchanged.

Second, use a zoom lens to shoot continuously from short focal length to long focal length. The sight distance remains the same, but the angle of view has changed.

Features: Highlight the theme and details.

Push has a clear theme goal, mainly to highlight the theme and details, and at the same time introduce the relationship between the whole and the part, the objective environment and the main characters in one shot. This subject and detail determine the direction and final placement of the lens. When the lens is pushed to the subject or details, it changes from a large perspective to a small perspective. As the minor part moves out of the picture, the subject or detail to be shown gradually becomes larger, which "forces" the audience's attention, and its left picture finally makes the subject or detail in the eye-catching visual center, giving people a distinct visual impression. For example, when shooting news, especially meeting scenes, we often make a panoramic view. Explain the environment first, and then push it to an important person who is speaking on the rostrum. This not only explains the environment, but also highlights the subject. For another example, when shooting an athlete standing on the podium to receive the award, it often advances from a panoramic view to a close-up of the athlete's face, so that the facial expressions and expressions that are not easy for athletes to see in the big picture or are excited or crying with joy are highlighted and emphasized, and the problem can be explained without words.
