The positioning of the light sources will define objects differently depending on the amounts of shading and highlighting. Lighting becomes critically important because what you show is just as important as what you don't show. Without proper lighting imporatant elements will not be seen if they are not well lit. Ideally, you want to replicate the real world three-dimensional aspects, and colors, for a 2 dimensional preview medium. Lighting is crucial for creating depth.
Lighting is crucial in producing quality video productions.
Lighting plays a major role in creating the illusion of this third dimension. Having a light that can produce enough foot candles is crucial in creating illusion that represents reality. The term, Fresnel, can be attributed to Augustin-jean Fresnel. Fresnel , who lived from 1788-1827, was a French physicist who studied light wave theory and developed compound lenses. It is the use of these lenses and lights that help create real world 3-D illusion in video production.
