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 benecial
to ne-tuning adjustments in the Colour
Matrix.
