When you first launch Mudbox you view the 3D scene through a perspective camera. This camera can be found in the Object List, named Perspective. The Front, Top, and Side cameras are collectively referred to as orthographic cameras. You can also create additional cameras.
Cameras are the digital lenses through which you view objects in Mudbox. You can look through any of the four cameras in the 3D View by default (Perspective, Front, Top, and Side) to view and evaluate your 3D models from many points of view.
You can save camera views using bookmarks. A bookmark saves the camera's properties as a preset to a tool tray you specify.
