High-Sensitivity
Shooting
While this unit permits you to vary the sensitivity
by changing the gain as with conventional
cameras, it supports two additional methods for
high-sensitivity shooting.
1. ISO 800 Hyper Gamma shooting:
Creating images while shooting using
Hyper Gamma
Selecting HG7-ISO800 or HG8-ISO800 from the
SPECIAL gamma table for the standard
sensitivity (ISO 450), you can obtain a sensitivity
setting equivalent to ISO 800.
These gamma curves have been created based on
the curves of Hyper Gamma 7 and 8 so that they
provide ISO 800-equivalent sensitivity.
As these settings have the same effect as when
you increase the gain, the S/N is slightly
decreased, but the dynamic range is maintained at
800%.
2. Cine-EI mode: Shooting with S-Log
and performing postprocessing
The unit enters Cine-EI mode if you set SHOOT
MODE to CINE-EI, using the <BASE
SETTING> page of the MAINTENANCE menu.
ISO 450 (standard sensitivity), 640, 800, or 1000
can be selected, requiring use of a light meter for
shooting in this mode,
As the gain does not change in this mode, the
higher you set the sensitivity, the darker the
camera image will become.
In the same manner as sensitivity-intensified
shooting with film cameras, the gain is increased
to the proper level in post-production for dark
shooting.
Although the output of the main line may become
dark, shooting at the proper level is enabled as
appropriate LUT for the selected sensitivity is
automatically applied to each of the VF and
monitor outputs,
As the gain is increased in post-production, the
higher you set the sensitivity, the more the S/N is
decreased, but the dynamic range is widened for
high-luminance signals.
