We can employ Computer generated images (CGI) to create visuals when photography is impractical. For several years CGI had been viewed as beyond the reach of all but the biggest spenders, but today this is no longer the case. Computer generated images can even be advantageous; don’t like the colour? just make some adjustments and render again – no need to re-book a photo shoot.
Compositing is the art of blending a computer generated image model into a real (moving or still) background to produce the illusion of the model's presence in the scene.
