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

Set "OPERATION" > "Auto Iris" >
"Iris Override" in the setup menu to
"On" (see page 117).
2
Set the MENU ON/OFF switch to OFF.

seen from the front of the camcorder.

power is turned on.
