Grain matching - ensuring that all of the elements in a composite, including those which were digitally generated, look like they were shot on the same film stock - is often one of the final steps in achieving a convincing integration of all of a composite’s elements. Nuke offers effects for synthetically creating grain and for reading in practically-created grain (grain derived from actual film stock).
