Changing the Reference Value for Automatic Iris Adjustment

Changing the Reference
Value for Automatic Iris
Adjustment
The reference value for automatic iris adjustment
can be changed to aid the shooting of clear
pictures of back-lit subjects, or to prevent blown-
out highlights. The reference value for the lens
iris can be set within the following range with
respect to the standard value.
• 0.25 to 1 (increasing by increments of 0.25):
About 0.25 to 1 stop further open
• –0.25 to –1 (decreasing by increments of 0.25):
About 0.25 to 1 stop further close
Also you can set the area where light detection
occurs.
To change the reference value
1
Set "OPERATION" > "Auto Iris" >
"Iris Override" in the setup menu to
"On" (see page 124).
2
Set the MENU ON/OFF switch to OFF.
3
Turn the MENU knob to change the
reference value.
Note
Be sure to confirm that the current shutter mode is
not ECS.
An indicator of the current reference value is
shown at the iris position indication (see
page 28) on the viewfinder screen.
To make the iris more open
Turn the MENU knob counterclockwise as
seen from the front of the camcorder.
Select one of 0.25, 0.5, 0.75, or 1.
To stop down the iris
Turn the MENU knob clockwise as seen
from the front of the camcorder.
Select one of –0.25, –0.5, –0.75, or –1.
The changed reference value is retained until
the power of the camcorder is turned off.
Even if the reference value is changed, it
reverts to the standard value every time the
power is turned on.
