Colour Matrix
The Colour matrix section allow you to fine-tune the cameras performance for individual colours
across the spectrum.
You can see in this figure that the color spectrum is divided into six sections, theses being Red, Green,
Blue, Cyan, Magenta and Yellow.
The Colour Matrix control allows individual fine-tuning of each of these colour sections without affect-
ing the response of other colour components. The controls allow for adjustment of Gain (Intensity) and
Hue (offset) of each colour.
Colour Gain
The Gain control of each colour component defines how intense that colour is represented in the im-
age that is produced by the camera. The default level (32) is a moderate gain which shows an even bias
between all pixels that contain the colour. I.e. a dark red with have the red component shown as vividly
as a bright red, this generally gives a balanced look to your colour representation.
.
By increasing the gain value, the camera will add additional intensity to all parts of the image per-
taining to this colour. For example, if you increase the Red gain value to 64 all pixels that are red in
the image will have a boost of colour compared to other colours in the image resulting in a more vivid
representation of this colour.
Conversely reducing the colour gain will take some intensity out of the target colour. This can be useful
in some lighting conditions where certain colours appear over saturated to the camera.
Colour Hue
The Colour Hue option adjusts the temperature or phase in which any colour is represented. When
looking at the colour spectrum, beyond the true colour points for each of the main colour adjustments
in the camera (Red, Green, Blue, Cyan, Magenta and Yellow there are areas where the colours transi-
tion to their neighbouring colour point.
