6.2.5 Performing a Black Reference Adjustment
Performing a Black Reference Adjustment, called Current Session Reference in some of the other
Phantom camera models, will calibrate the camera at its current settings to eliminate noise and
produce the best images possible.
STEP-BY-STEP PROCEDURE
1.
Cover the lens with the lens cap.
2.
Press the BREF (Black Reference) selector in the Power Off Display.
RESULT: The BREF selector will change to a counter that will count down to zero. When the Black
Reference adjustment has completed its process the camera will return to the LIVE PRE screen.
NOTE
The Black Reference adjustment process should be performed whenever your camera settings
are changed.
6.2.6 Selecting an Exposure Index
The Exposure Index is an advanced feature, one which you may never need to use. It is an amount
by which it is possible to over or underexpose a light sensitive material and, with standard processing,
still produce acceptable results. By referring to the exposure index in the LCD display and working in
stops, you can fine tune your exposure.
Essentially it indicates the effective ISO, or sensitivity of the camera under current conditions.
STEP-BY-STEP PROCEDURE
1.
From the Power Off Display Screen:
a.
Press directly on the Exposure Index field to select the field.
b.
Pressing directly on the value a second time increases the value.
c.
Pressing approximately 1/3 the screen height above the value to decrease the value.
d.
View the live image. If the Exposure Index is too high or low the image will appear distorted.
e.
Repeat until the desired value is displayed.
