Author says “As this is a compositing tutorial, not a lighting/rendering tutorial, I’ll assume that you have at least a basic knowledge of V-ray, and that you are able to render out your own scenes already. We’re going jump straight ahead into setting up the different render elements for the compositing process”. He also covers few extra post production technique such as Chromatic Aberration and Depth of Field, as well as how to emulate a Cross-processed look.
