What is Compositing?
Compositing is the process of combining different elements to create a single image. This can involve anything from adding objects into a scene that were not originally there (or removing objects that were) to creating entirely CG environments.
VFX compositing is a complex process that requires a great deal of skill and experience. In order to create believable and realistic composite images, VFX artists need to have a strong understanding of both art and technology. They must be able to manipulate digital assets to match the look of other live-action CG footage and combine those elements in a way that is invisible to the viewer.
With the advent of advanced learning tools like neural networks, VFX compositing is becoming increasingly complex and sophisticated. However, at its heart, the goal of VFX compositing remains the same: to create images that are greater than the sum of their parts.
