Chapter 2: Operations in DV mode
Shooting in manual mode (continued)
As you shrink the aperture to a near closed state,
resolution will decrease due to light diffraction.
You can prevent this by adjusting the shutter
speed and increasing the aperture size.
Adjusting the white balance and black
balance
When white balance adjustments are performed,
black balance adjustments are performed at the
same time.
White balance
In order to reproduce the white accurately, adjust
the ratio between the three RGB primary colors. If
the white balance is not adjusted properly, not only
will the white be reproduced poorly but the color
tones of the entire screen will also be downgraded.
When you are shooting in manual mode, readjust
the white balance whenever lighting conditions
change.
You can store white balance adjustments to Ach
and Bch of the Function Menu.
You can also use the preset values.
Use the settings to suit the shooting conditions.
Black balance
Adjust the ratio between the three RGB primary
colors to reproduce black accurately. If the black
balance is not adjusted properly, not only will black
be reproduced poorly, but the color tones of the
entire screen will also be downgraded.
Black balance adjustment is usually not necessary,
but be sure to perform it in the following cases.
When using the camera for the first time.
When using the camera after extended periods
of disuse.
When using the camera after large changes in
ambient temperature.
After setting the shutter speed to standard or low
speeds.
After switching between progressive mode and
standard (60i) mode.
