 Setting the Exposure
(1) Exposure Mode
Select from [Auto], [Manual], [Auto (Flickerless)] or
[Auto (Shutter-priority AE)].
If [Auto] is selected for [Day/Night] under [Camera] in
the Setting page (p. 53), select [Auto], [Auto
(Flickerless)] or [Auto (Shutter-priority AE)].
[Auto]
The exposure is controlled automatically.
[Manual]
The exposure is set by adjusting the shutter speed,
aperture and gain values manually.
[Auto (Flickerless)]
In this mode, video flickering caused by fluorescent
lights, etc., can be reduced. The shutter speed is
automatically adjusted according to the brightness
of the environment in which the camera is used.
[Auto (Shutter-priority AE)]
In this mode, the desired shutter speed can be
specified.
(2) [Exposure Compensation]
When [Auto], [Auto (Flickerless)] or [Auto (Shutter-
priority AE)] is selected for [Exposure], the exposure
compensation value desired can be selected from
nine levels (-4 to +4) using the slider.
To darken the image, select a negative value. To
brighten the image, select a positive value.
(3) [Metering Mode]
When [Auto], [Auto (Flickerless)] or [Auto (Shutter-
priority AE)] is selected for [Exposure], the metering
mode can be selected from [Center-Weighted],
[Average] or [Spot].
For an explanation on each item set in [Metering
Mode], see [Metering Mode] in the Setting page
(p. 51).
(4) [Shutter Speed]
When [Manual] or [Auto (Shutter-priority AE)] is
selected for [Exposure], select the shutter speed
desired. If [Manual] is selected, set the shutter speed
in the range of [1/1 sec] to [1/16000 sec] from a pull-
down menu. If [Auto (Shutter-priority AE)] is selected,
set the shutter speed in the range of [1/2 sec] to
[1/16000 sec] from a pull-down menu.
When capturing a moving subject, selecting a higher
shutter speed can reduce blurry video capture.
(5) [Aperture]
If [Manual] is selected for [Exposure], set a desired
aperture value.
Moving the slider to the left closes the aperture and
darkens the image. Moving the slider to the right
opens the aperture and brightens the image.
(6) [Gain]
If [Manual] is selected for [Exposure], set a desired
gain value.
Moving the slider to the left decreases the gain
(sensitivity to brightness) and darkens the image.
Moving the slider to the right increases the gain and
brightens the image.
