Cameras in Maxwell Render™ operate completely different from those in other render engines. Traditionally, most render engines use a pinhole camera. This type of camera simulates a tiny hole that allows light rays coming from the scene to reach the viewing surface. Instead, Maxwell Render™ simulates a real camera with the associated lens set, diaphragm aperture, diaphragm blades and various other settings. By using this type of camera model Maxwell Render™ can automatically simulate depth of field or aperture diffraction.
Along similar lines, motion blur in Maxwell Render™ is not produced as a post-process. Maxwell Render™ considers the moving objects to have random positions along their trajectories during the camera shutter speed time. This creates a natural and realistic motion blur.
Maxwell Render's SimuLens™ system allows you to simulate the shape of the diaphragm, creating realistic lens diffraction effects. It is also possible to simulate the scattering of light inside a lens system, an effect typically called "bloom".
