an appropriate ND offset value from a previous adjustment
you made. Use the ND filter selection page on the
subdisplay.
The offset values ND: 2 to 5 are stored with respect to the
white balance stored for ND: 1 as the reference.
For the ND offset adjustment, see "5-3-7 Storage of the
OHB File" (page 94).

At 1 on the first line, the gain value is selected from
among the following: –6 dB, –3 dB, 0 dB, 3 dB, 6 dB, 9
dB, and 12 dB. The corresponding ISO sensitivity is
displayed in parentheses. For 2 on the first line, you can
select either dynamic range or latitude for the indication
(see "Indications of the ISO sensitivity and dynamic
range" mentioned later).
On the second line, the color temperature is selected from
TUNGSTEN or DAYLIGHT.
With DAYLIGHT, electrical gain of 5600K is ON.
At shipment, the gain is set to 0 dB, and the color
temperature is set to TUNGSTEN.
The white balance adjustment value is fixed at the preset
value (3200K).

Indications of the ISO sensitivity and
dynamic range
The ISO sensitivity value displayed on the Gain setting
page is defined as "the value with which the video input
becomes 20% when shooting a gray-scale chart of 18%
reflection rate."
Note that the video output value with respect to this input
will vary depending on the selected gamma.
Either dynamic range or latitude can be selected for the
indication.
The value displayed with % as a dynamic range shows the
limit on the high-luminance side in percentage (100%=
input level) in a case where the white of the gray scale
provides 100% (700 mV) output with the ITU-R709
gamma (standard gamma).
The value displayed with E as a latitude shows the latitude
on the high-luminance side by an f-stop value, using a
gray-scale chart of 18% reflection rate as the key light.
The latitude at the low-luminance side can be reproduced
up to approx. –6.5 stop at 0 dB.
Note
As the dynamic range indication shows a value for the
input video, the dynamic range of the output video is
limited by the output settings as follows:
