Description |
This programme is highly integrated with the text or Units 10 and 11. It is presented
by the author, Dr. Geoffrey Wexler who introduces a number of demonstrations (many
for the first time on television) designed to question nai?ve assumptions or instinctive
explanations for colour effects. All of the demonstrations were recorded using television
cameras on location. An industrial lighting laboratory shows the effect of different
?white? lights used as illuminants in a domestic environment. The Colour Scientist
Dr. Arthur Tarrant shows how an arbitrary colour can be matched using a particular
combination of three coloured lights. A Research Scientist, Dr. Jim Bowmaker, demonstrates
the response of three colour receptors of the eye. Complex and not-yet-understood
colour contrast effects are shown (e.g. Lande). Finally, a brain scientist, Dr. Semir
Zeki, points out the overriding control and influence of the brain (visual cortex)
on colour perception regardless what is physically happening to the lighting of a
scene. |
