High-Sensitivity Shooting
While this camera permits you to vary the sensitivity by
changing the camera 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 camera 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 camera 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 camera 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 camera 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.
