You create lights with various properties to illuminate your scene.
Lights can cast shadows, project images, and create volumetric effects for atmospheric lighting. 3ds Max provides two kinds of light objects: standard lights do not use physical values, while photometric lights are physically accurate and work best with realistic models.
Cameras set up a viewpoint on your scene. Camera objects in 3ds Max have real-world controls for lens length, field of view, and motion control, and so on.
