Lighting technique using directional light and attached shadows to create three-dimensional form and volume in a subject.
"3D Modeling" (also "Modeling", English modelling) in film lighting does not refer to a category of equipment or gear, but rather a lighting technique. It means shaping a subject with light so that a flat, two-dimensional camera image gains the impression of volume, depth, and plasticity. The term originally comes from the visual arts, where "modeling" refers to the creation of three-dimensional form through light-dark contrasts.
Important distinction: In the field of computer graphics/VFX, "3D Modeling" refers to the creation of digital 3D objects on a computer. In the set, grip, and lighting context, on the other hand, it is about the physical "modeling" of a real subject through light direction.
Crucial for the plastic effect are the so-called attached shadows – that is, the shadow areas on the subject itself, where it is turned away from the light. These shadows describe the roundness and contours of an object and convince the eye that the image possesses depth.
Modeling is primarily controlled by the position of the key light (Key) relative to the camera and the subject. A lateral key position increases plasticity, a camera-near position reduces it. The amount of fill light (Fill) can be used to fine-tune the contrast between the bright and shadowed sides – and thus the degree of modeling. In classic three-point lighting (Key, Fill, Back), the targeted modeling is the core of the spatial effect that the lighting imparts to the subject.
As a cinematographer, I work closely with the 3D artists to ensure the virtual camera settings sync with my real camera work. Precisely documenting focal lengths, camera movements, and lighting setups is essential so the 3D models can later be seamlessly integrated into my shots.
For me, 3D modeling opens up entirely new narrative possibilities, especially for fantasy or historical material. I can already visualize scenes with previz models during pre-production and communicate my vision precisely to my team. The close collaboration with the 3D supervisors is crucial for the final artistic outcome.
3D modeling is a significant cost factor that requires careful planning. I need to define the scope of the required assets early on and factor in budgets for software licenses, hardware, and specialized professionals. Scheduling is critical, as complex models can take several weeks to develop.
