3. Shooting: Adjusting the Brightness 37
[Tip]
Change the gain preset value according to the ISO/GAIN
switch (J) setting.
Controlling the gain temporarily (fine
adjustment)
Turn the assignable dial (page 41) assigned
with the ISO/Gain/EI function, to adjust the
gain value set by the ISO/GAIN switch (J).
This is useful when you want to adjust the
exposure by one step without changing the
depth of field.
The adjusted gain value is canceled by
switching the ISO/GAIN switch (J), changing
the base sensitivity, setting AGC to On, or
turning the power off.
[Tip]
You can also assign this function to the multi-function
dial (page 41).
Adjusting the Exposure Index
In Cine EI mode, it is assumed that video
output with MLUT set to Off is recorded as the
main signal. By changing the brightness of
the image with MLUT On to match an EI value,
you can check the result of post-production
exposure sensitivity adjustment while
shooting.
You can change the EI value by setting the
ISO/GAIN switch (J) to H, M, or L.
[Tip]
You can change the EI value of each switch position
using ISO/Gain/EI >Exposure Index<H>/<M>/<L>
(page 73) in the Shooting menu.

obtain better shooting results using the ND filter.
