What is the axis law of TV camera?

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.

kinematic axis

That is, a person or an object in motion, and its motion direction constitutes the motion axis of the subject. It is an invisible line produced by the subject's motion, or called the subject's motion trajectory. When shooting a group of connected lenses, the shooting direction of the camera should be limited to the same side of the axis and not beyond the other side of the axis. Otherwise, there will be an "off-axis" lens, and the direction of the lens will be contradictory, which will lead to confusion in the spatial relationship of the picture.

The faster the subject moves, the more obvious the role of "axis" is. 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 rule" and avoid the lens being limited to one side of the axis, but to express the objective reality space in a changeable perspective.

This requires effective means, or some reasonable factors, or other pictures as a transition to play the role of "bridge", which not only avoids the "off-axis" phenomenon, but also forms the diversity and richness of picture language.
