By default, Maya has four cameras that let you view your scene in a panel: the perspective camera and the three orthographic cameras (side, top, front) that correspond to the default scene views. You look through these cameras (panels) as you model, animate, shade, and texture objects. To switch among these cameras, open the Panels menu and select a camera from the Perspective or Orthographic submenu.
You can also create your own cameras to view your scene in different ways. See Maya camera type for a description of the kinds of camera available.
To create a new camera
The Create Camera Options for that camera type appear.
To view your scene through the new camera
See Aim a camera, Look through a camera or object and Frame all objects for more on working with cameras in your scene.
