Configuring User-Defined Correction Tables
The default gamma correction value when measuring f Stop levels is 0.45, but you can also
use a user-defined gamma correction table that matches the gamma characteristics of the
camera that you are using.
User-defined correction tables are not deleted even if you initialize the LV 5333.
You can create and store up to three user-defined correction tables.
As an example, the following procedure shows how to create a user-defined correction table
that matches a camera's gamma characteristics.
Set the camera's f Stop value to F5.6 beforehand, and put an 18 % gray chart in the area that
you will film.
1. Adjust the lighting so that the displayed luminance level of the 18 % gray chart is 45.0 %
(for example) on a camera whose f Stop value is set to F5.6.
See section 9.3, “%DISPLAY Screen Description.”

GAMMA, and select USER-1.
In this example, explanation will be given for USER-1, but USER2 and USER3 can also
be created in the same way.
4. Press
CAL.
When you press
CAL, a user-defined correction table appears in the lower left of the
screen, and the luminance level appears as a 10-bit value (0% is displayed as 64, and
100% is displayed as 940) close to the cursor.
