Colour Matrix Tab
The Color Matrix features 64 levels of
adjustment of Gain (Intensity) and Hue
(offset) across six color sections, Red,
Green, Blue, Cyan, Magenta and Yellow,
and allows individual fine-tuning of each
of these without affecting the response
of other color components.
You can also view an online video that
covers this section.
Colour Gain
The Gain control of each colour
component defines how intense that
colour is represented in the image. 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.
Increasing the gain valueb will add additional intensity to all parts of the image pertaining 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 transition to their neighbouring colour
point. P120 Colour Matrix controls allow you to adjust the colour offset in a negative (counter clockwise) or positive
(clockwise) direction, effectively moving the cameras response to any colour towards its neighbouring colour
transition point. Adjusting individual colour Hue can assist dramatically in matching colour representation from the
camera to true-to like colours or matching P120 to other cameras in your production.
Using a Colour Chart
It is recommended to utilise a colour chart or colour chip chart when adjusting the Colour Matrix controls. These
charts are available readily and have colour chips for each of the colours that the camera can adjust. By utilising a
colour chip chart you are more easily able to see the impact of any adjustment you are making.
Using a colour chip chart such as the Datacolor SpyderCheckr can be beneficial to fine-tuning adjustments in the
P120 Colour Matrix.
