ABSTRACT
Two sounds cannot be combined to produce a third pure sound but as we have discussed in Colour (page 12), by combining two or more colours a third colour can be created in which there is no trace of its constituents (e.g. red + green = yellow). The eye acts differently to the ear. The eye/brain relationship is in many ways far more sophisticated than a video camera and can be misleading when attempting to analyse the ‘colour’ of the light illuminating a potential shot.
