Thea Render --- IBL--- Tutorial #12
Image-based lighting (IBL) is a convenient way to add illumination to your scene, coming from captured photos of the surrounding environment. Since a photo of a real scene can be used, the lighting is highly convincing and enhances the realism of your renders. In most cases, the images used for this kind of lighting need to be of high dynamic range (hdr) in order to provide enough lighting for a scene.
