What is VFX and Compositing

The definition of a composite, is combining two or more images together to create one image. The definition of Visual Effects (VFX) is the process where imagery is created or manipulated outside of the  live action footage, for example a 3D modelled monster created separately to the film footage of people running away. With compositing, it is possible to put VFX overlaid on top of the film footage making on piece of moving image. With new technologies we can now do this digitally as well as using colour correcting software and other rendering packages to make the VFX look seamless within the film.
