Gamma: “Gamma” is a global setting that determines how gray shades are displayed
between minimum input (black) and maximum input (white) for all signals. A good
gamma setting helps to optimize blacks and whites while ensuring smooth transitions
for the “in-between” values utilized in other grays. Unlike “Brightness” and “Contrast”
controls, the overall tone of your images can be lightened or darkened without changing
the extremes and all images will be more vibrant while still showing good detail in dark
areas when using the “Gamma” control.
In all but the most unusual situations, the appropriate “Gamma Selection” (see below)
will produce accurate colors and a satisfying contrast level. However, it is sometimes
necessary to adjust the red, blue and green gamma curves individually. To do this,
select Gamma from the White Balance sub-menu and use the left- and right-arrow
buttons to manipulate the on-screen slidebars.
Gain: Use the Gain controls in the White Balance sub-menu to correct color imbalances
in the bright areas of the image. A good way to do this is to use a test pattern consisting
mostly of solid white areas, such as an 80 IRE “window” pattern. If the white areas
contain traces of red, green or blue, decrease the Gain for that color.
Offset: Use the Offset controls in the White Balance sub-menu to correct color
imbalances in the dark areas of the image. A good way to do this is to use a test pattern
consisting mostly of dark gray areas, such as a 30 IRE “window” pattern. If the gray
areas contain traces of red, green or blue, decrease the Offset for that color.
Store Color Temp.4/Store Color Temp.5: When you are finished adjusting the
Gamma, Gain and Offset, select Store Color Temp.4 or Store Color Temp.5 to store
your settings. To recall them, set the Color Temperature to +4 or +5 in the Image
Adjustment menu (refer to “Picture Quality Adjustments,” earlier in this section).
