Renderman24 for Blender - Cameras in Blender

Reference Renderman 24 For Blender Doc Cameras in Blender Depth of Field in Blender Depth of Field (DOF) is a photographic technique used to convey scale (size) and areas of interest in a composition. Clever usage can lead a viewer to certain parts of your image and increase photorealism by correctly mimicking a real-world lens. RenderMan provides controls for realistic and compelling images with depth of field. There are also options that are non-physical but great for creating art-directed imagery. ...

Renderman24 for Blender - Rendering in Blender

Reference Renderman 24 For Blender Doc Rendering in Blender Integrators in Blender Integrators take the camera rays and return results to the renderer. For the main integrators these are estimates of the light energy (radiance) from the surfaces seen from the outside along the rays. These main integrators are responsible for computing the overall light transport, that is, light that travels from a light source through your scene from object to object (or through objects and volumes) to reach the camera. Interior integrators assist in specialized cases by handling the light within surfaces or volumes. We provide three main production quality integrators, though users can substitute their own. ...
