[Year 12 IPM] OT: Green Screening with computers

[Roland Gesthuizen]

One of the original wiggles changed from a green shirt for this reason.
Anybody like to guess who?  The popularity of green stems from the
observation the note that people and skin colour don't generally have any
green shades whilst they may have some red and blue components (lips, veins
etc).  I read that with the right 'paint', you can even use a UV light to
make the background key light up in even dark situations!

StarWars got around the give-away coloured edge that this effect often gives
to films by using a computer with a travelling matt. From memory, it was
made with the same PDP11 that I have fond memories of using at Swinburne.
:-)

Regards Roland
