Sections: Position, Rotation, Other
At the top right of the Camera setup screen, there are 3 sections available: Position, Rotation and Other with Zoom function. Picture below.
The X, Y, Z coordinates show the exact position of the camera in the studio in relation to a point X = 0, Y = 0 and Z = 0, the position of which was set by a graphic designer of a particular studio. If you want to find this point in a studio, type a 0 value in the fields X, Y and Z – and a camera will move to this point. In the case of the presented studio, this point is located more or less on the floor behind the desk.
To enter a specific value, position your cursor at a beginning of a value field and drag (select) the entire field, then type in the desired value with a keyboard. You can also change the value by clicking on the white up/down arrows on the right side of each value field.
Movement in the X axis: moving the camera trolley to the right will mean increasing the positive values for our studio, and moving the camera trolley to the left – increasing the negative values.
Movement in the Y axis: raising the camera above the floor – increasing the positive values, while lowering the camera below the floor – the negative ones.
Movement in the Z axis: if you increase the positive values – the camera moves away from the desk, and if you increase the negative values – the camera moves forwards, deep into the studio.
Our virtual camera has no limits!
Note: in the studio ,all the values of X, Y, Z are given in centimeters when they represent a linear motion. This means that, for example, a value of 100.80 means 100.8 cm in a virtual 3D studio. If the values refer to the circular motion, they are expressed in degrees, that is, for example, a value of 45.00 for Rotation stands for 45 degrees.
The coordinates represent a rotation, that is, an angle at which the camera is pointed. The camera trolley is stationary and the camera stands still, but it can ‘look’ in all directions. In this set design, the Rotation 0 point means that the camera is pointed exactly straight at a Talent (a presenter) behind the desk.
Movement in the X axis means increasing the positive values for this studio – namely lifting the camera lens on a tripod (up until the camera is looking at the ceiling). Increasing the negative values – tilting the camera lens down (until the camera sees the studio floor).
Movement in the Y axis: camera rotates to the right with the increase in the negative values, and to the left – when the positive values increase.
Movement in the Z axis means tilting the camera from side to side. In an actual film or TV studio, this movement is called cant and is used, for example, to achieve the Dutch View, where a camera is tilted slightly to one side in relation to a vertical axis, all resulting in tilting of the image. (See the picture – a description of camera movements at the beginning of this section).
Zoom function: this feature sometimes substitutes a shot where a trolley moves straight ahead, but the difference between these two methods of operating the camera is significant. Zoom enlarges or reduces the camera image without causing changes in a perspective and in the image of a studio space. The trolley movement, on the other hand, brings you closer to an object, just as zoom does, but at the same time it changes the perspective and image of a studio the camera ‘sees’.
