Color 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.
Color Gain
The Gain control of each color
component defines how intense that
color is represented. The default
level (32) is a moderate gain which
shows an even bias between all pixels that contain the color, i.e., a dark red will have the red component shown as
vividly as a bright red, this generally gives a balanced look to your color representation.
By increasing the gain value, the camera will add additional intensity to all parts of the image pertaining to this
color. Conversely, reducing the color gain will take some intensity out of the target color. This can be useful in some
lighting conditions where certain colors appear over saturated to the camera.
Color Hue
The Color Hue option adjusts the temperature or phase in which any color is represented. When looking at the
color spectrum, beyond the true color points (Red, Green, Blue, Cyan, Magenta and Yellow), there are areas where
the colors transition to their neighboring color point. Color Matrix controls allow you to adjust the color offset in a
negative (counter clockwise) or positive (clockwise) direction, effectively moving the cameras response to any color
towards its neighboring color transition point.
Adjusting individual color Hue can assist dramatically in matching color representation from the camera to true-to
like colors or matching your camera 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
camera Colour Matrix.
