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.
There are two types of user-defined correction tables. The first type consists of tables that
are created using the LV 5490 and is made up of the USER1 to USER3 tables. The second
type consists of tables that have been created externally using a device such as a PC and is
made up of the USER_A to USER_E tables. These tables are not deleted even if you
initialize the LV 5490.
●
Creating User-Defined Correction Tables Using the LV 5490.
You can create and store up to three user-defined correction tables on the LV 5490.
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.
For details, see section5.4.3, “%DISPLAY Screen Description.”
2. Press F•7 up menu.
3. Press F•1 CINELITE DISPLAY to select f Stop.
4. Press F•2 f Stop SETUP.
5. Press F•5 GAMMA and then F•1 GAMMA SELECT to select USER1.
In this example, explanation will be given for USER-1, but USER2 and USER3 can also
be created in the same way.
