THE BIGGEST LIAR IN OUR
INDUSTRY IS GREEN SCREEN
|Most of us have heard the
expression, "The camera never lies". That's right, it doesn't but in collusion
with postproduction it frequently does.
What is Green Screen?
Most of what we film these days
has some level of visual adjustment, known as effects, which very subtly
influences the tone or mood of the shot. Often you won't even notice it's been
done. However, the biggest visual liar in our industry is Green Screen. What
you see simply isn't true.
Green Screen technology is the technique used
to create the illusion of an imaginary or distorted location. Being able to
'key out' (i.e. isolate) a green background to become transparent, enables the
producer to superimpose foreground imagery on top of a different background,
whether that's a photographic image, graphic, animation or perhaps another
So why would you want to do that?
Well, imagine you want your viewers to picture you in a faraway
country. Going there might prove rather time-consuming and expensive. Creative
ideas may work better in locations that are relatively difficult or impractical
to set up in real life, for example, on the moon. What if you want to change
the scale of the presenter to be bigger or smaller than he or she really is?
Altering foreground scale compared to background scale during the shot is often
used to intensify a situation. You may simply want a more interesting
background than being sat in a boring office with a plain wall. Green Screen
allows them all.
How's it done?
Any colour can be 'keyed out' but producers tend to choose green because
it's the furthest away from natural skin tones. A studio set up is usually the
best choice as it provides the correct environment for carefully configured
lighting and microphones. For technical reasons, which we won't go into here,
more spacious studios offer far better quality control. With the use of full
height backdrops, presenters can also be stood up so they can be seen from head
to foot, or whatever looks best in frame. Quite recently we created an office
setting in the middle of a field, giving the presenter full scope to move
around and a magical door to theme the storyline around. Neither could have
been filmed in a real field, not least because the cows wouldn't have left us

What's the end result?
Of course there are less
complex scenes but within reason nothing is impossible, turning the impossible
into possible, the unbelievable into believable and changing the boring into
