What is the shooting axis and its classification?

The concept of shooting axis refers to an imaginary virtual straight line formed by the orientation, movement direction and communication relationship between objects.

Axis is the basic element to establish the picture space, form the sense of picture orientation and express the position relationship of the subject.

The shooting axis is divided into:

First, the direction axis. Indicates that the subject is stationary, that is, the position has not moved. In this way, the "axis" depends on the connecting line between the subjects or the vertical line from the subjects to the background plane. Take the person being photographed as an example. The straight line of sight of the subject is the axis, and the line connecting him and the other party is also the axis.

Second, the axis of motion. That is, a person or an object in motion, whose motion direction constitutes the motion axis of the subject.

When shooting TV, we should abide by the law of the axis to prevent the pictures before and after the axis from being assembled. However, in order to enrich the language of TV pictures, it is often necessary to break the "axis law" and avoid the lens being limited to one side of the axis. Instead, it takes a changeable perspective or other pictures as a transition and plays the role of a "bridge", which not only avoids the "off-axis" phenomenon, but also forms the diversity and richness of the picture language.

How to solve the cross-axis transition?

1. By moving the lens, the camera "moves over" the axis, and the off-axis transition is realized in the same lens, that is, the process of shooting by using the motion of the camera to cross the original axis.

2. Using the change of the action route of the subject, the axis changes in the same shot, forming an off-axis transition. ?

3. Use neutral lenses or insert two off-axis lenses to alleviate the visual jump caused to the audience.

4. Insert a close-up shot of the main body between the two shots passing through the shaft to make the transition.

5. Use two axes, one axis crosses and the other axis completes the unification of picture space.
