There are two types of cameras, the studio (or 3D) cameras and the orthoganal cameras. The Left, Right, Top, Bottom, Front, and Back cameras are orthogonal cameras - they produce orthographic projections. In an orthographic projection, all objects appear flat. These cameras are different from the perspective views provided by the other cameras. In a perspective view, the scale of objects diminishes as their distance from the camera increases. The orthogonal cameras display flat perspectivefree scenes; the studio cameras display scenes in 3D. I hope this helps, Ericroy
