You can transform cameras interactively in the Player or set values in the transformation fields in the Cameras tab—see Transforming Objects.
Interactive transformations are applied using the camera's local axis, but its position is recorded using global coordinates.
Dollying, Trucking, and Orbiting the Camera
You can dolly, truck, and orbit any camera to view your scene from different angles.
Camera movements are not the same as zooming and panning the Player. For example, if you need to view the pixel output of Reaction up close, you should zoom in. But if you want to move the camera itself, you should dolly.
