Creative content is increasing being handled in digital form. This simplifies
the process of capturing, storing, manipulating, duplicating and delivering the
content to the target audience. Content is king. The king has
to be kept alive by showing it through multiple delivery channels. This is
easier when the content is handled digitally.

The most frequent tasks for digital work in film productions are not
spectacular effects, but the touch up work-removing disturbing picture
elements, correcting colour and light, or merging synthetic picture elements
with (normal) photo-chemical directed scenes. For historical scenes, this
would mean replacing modern street lamps or advertising banners on the
screen.

Similarly, you can place together real camera shots with shots from the
computer using the technique of overlapping points; picture for picture. Such
fine work is part of the daily time-consuming routine of visual effects'
experts-improvements and optimi-sations that produce the 'unbelievable'
effects for a spectator to see.

Not only does VFX influence the aesthetics of the film; it also changes the
entire production process considerably-thus demanding special know-how
and equipment. Whether computer tricks will be used at all and in what
scope, depends on the cost of the tricks and the relative cost of an
alternative.
