3D animations encompass all the camera movement techniques used in live action movies. As compared to live action films, fancy camera movements can be easily done in 3D animations at cheaper rate. No rails or cranes are required to carry cameras.
Dolly/Tracking technique is also known as ‘Tracking shots’. This technique is used to push the camera on the tripod with wheels on a rail (curved or straight). Generally, a flat platform is used for the same. It is said that ‘Dolly’ refers to moving the camera towards and away from the subject, whereas ’Tracking’ refers to moving the camera sideways.
This technique is used to rotate the camera to the left or right in the same position.
This technique is used to rotate the camera to look up or down in the same position.
This technique is used to raise or lower the camera on a pedestal with respect to the subject.
This technique is a combination of dolly, pedestal, tilt, and pan techniques. Follow shot keeps the subject within the frame when subject moves around. It is always difficult to shoot a moving object, but the software in 3D animation simplifies the process and makes everything fall in place.
Dolly Zoom (Vertigo)
In this technique, the camera moves towards or away from the object for adjusting the zoom angle in such a way that the subject size remains consistent in the entire frame. When the zoom changes, the perspective also changes. Therefore, distant objects appear smaller and closer objects appear larger. When the camera dolly zooms in, the background objects stretch and the foreground objects shrink. When the camera dolly zooms out, the background objects shrink and the foreground objects stretch. The dolly zoom out makes the subject appear powerful or magical.
