Color Matrix is an advanced color matching tool,
which previously was reserved for video engineers
to match the HD-SDI output of cameras in a
broadcast environment. In Phantom Miro M- and
LC-series cameras a user ‘Matrix’ can be specified
to fine tune the color of both the Cine image and
HD-SDI output.
By adjusting the user ‘Matrix’ the image can be
finely tuned, so that individual colors are adjusted
in terms of tint and saturation. A common use for
this is to accurately match the color with another
camera on the same shoot.
Tone allows manual control over the tone curve
of the image. Tone curves change the shadows /
highlights relationship between the original values
(on X axis) and resulting values (on Y axis).
Tone curves can be useful to boost midtones of
the image without effecting highlights or shadows,
for example. They can also be used to push the
darks lower, which may result in richer images
when detail in the shadows are not required. There
is a relationship with overall image gamma, which
has a predefined curve, which is the equivalent of
Rec709.
The Production Area Offset is used to move a user-
defined ‘Production Area’ displayed on the LCD or
attached monitor. By default, the ‘Production Area’
is displayed in the center of the image display area.
