Noun explanation: the principle of position allocation of mixed triangle aircraft

Triangular principle of aircraft position distribution

The triangle principle of aircraft position distribution is used to guide the distribution principle of aircraft position when shooting a scene. Its main functions are

It is to ensure the consistency of visual image and spatial modeling in each shot.

(A) the relationship between the axis position of triangular aircraft

When shooting a dialogue, you can usually set up three cameras to form a bottom line that is in phase with the relationship axis.

Parallel triangle. There is a triangle on each side of the relationship axis, so you can use either side when shooting.

Triangle arrangement, but you can only choose one side, and you can't shoot the other side beyond the relationship line.

1. Internal dihedral corner seat

As shown in the figure, the positions 2 and 3 of the two sub-shots at the bottom of the triangle are both in the two sides of the dialogue. The sub-shots.

They're all single shots. The switchboard 1 appears in each shot after connecting the shots of two extensions 2 and 3.

The number of characters is 2, 1, 1. 2 and 3 are called internal dihedral corner seats respectively.

2. External dihedral aircraft position

As shown in the figure, the two extensions 4 and 5 are located outside the two sides of the dialogue, and both of them are shot from behind the two sides of the dialogue.

Shoulder double lens. After the switch connects two extended shots, the number of characters in each shot is as follows

2, 2, 2, 4 and 5 seats are called dihedral corner seats.

The principle of space allocation of dihedral plane position composition is: the speaker facing the audience accounts for 2/3 of the picture; 65,438+0/3 is the dorsal side,

And often limited to the tip of the nose does not exceed the contour of the cheek. If people with backs are adjusted to be empty, it will be more prominent.

Loudspeaker.

3. Angle position of internal and external combination

As shown in the figure, there are 2 seats and 5 seats, 2 seats adopt inner upper dihedral seats and 5 seats adopt outer upper dihedral seats.

Called the combination of internal and external dihedral angles; The same is true for 3 and 4 seats.

4. Apparent horizon rule

When the two sides of the conversation are at different heights (for example, one side is standing and the other side is sitting), the total shot should be taken at the average height.

Explain the relationship between the two; Shooting people with high views from an upward angle shows the subjective feelings of people with low views; along with

Shooting people with low viewpoints from a downward perspective shows the subjective feelings of people with high viewpoints.

(2) the triangle position of the motion axis

To express the action (walking and running) with a split lens, take the action route as the axis and put the seat triangle on the action.

The same side of the route; When shooting an action that changes direction, you should show the change of direction in a shot.

As shown in the figure, if the camera mount is assembled in the order of 1, 2, 3, 4 and 5, the number of people in each lens is constructed.

It becomes the relationship of 3,3, 1, 2,3.
