PROGRAM OUTPUT MONITOR

Again, a search of the Internet

for “video monitor calibration” w

ill yield a large number of resources, both

free and commercial. If you have television monitors connected to your outputs, though, you can make
further use of the color bars. The approach is somewhat similar to what we did for our video sources, in that
the first adjustments are to ensure that black and white levels are correct. Color calibration is performed
afterward.

First, warm up your monitor for at least 10 minutes (some sources recommend a half-hour), to stabilize its
output. Dim room lights and window light, to eliminate light sources that might skew your color perception.
Pass the color bars from your camera through to program output (or use a color bars image in one of the

Media Players

for this purpose.

COLOR ADJUSTMENTS

Having set the black

and white levels earlier, let’s continue…

NTSC

1.

If your monitor has a

“Blue

-

gun only” setting, enable it. Depending on the brand of your monitor, the

alternating bars will appear either as light gray and black, or blue and black (Figure 384).

2.

If the monitor lacks a “Blue

-

gun only” feature, you can obtain a colored filter such as a Kodak Wratten

#47B gel, and hold that between your eyes and the monitor for a similar result.

3.

Tweak the

Color

(or

Saturation

) knob until the small rectangular patches at very bottom of the tall

upper bars on the extreme right and left of your screen merge with the tall bars above.

4.

Tweak the monitor’s

Hue

control

until the small rectangles beneath the third and fifth tall upper bars

likewise blend into bar above.
