[Spot]
The center of the screen is metered.
An appropriate exposure can be achieved for the
subject at the center of the screen regardless of the
brightness/darkness on the periphery of the screen.
Use this mode if you want to adjust the exposure to
the center of the screen because the subject is
receiving a spotlight or backlight, etc.
4 [Shutter Speed]
When [Manual] or [Auto (Shutter-priority AE)] is selected
for the exposure mode, select the shutter speed desired. If
[Manual] is selected, set the shutter speed in the range of
[1/1 sec.] to [1/8000 sec.] from a pull-down menu. If [Auto
(Shutter-priority AE)] is selected, set the shutter speed in
the range of [1/8 sec.] to [1/8000 sec.] from a pull-down
menu.
5 [Aperture]
If [Manual] is selected for the exposure mode, 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 the exposure mode, 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.
Important
If the subject is a traffic signal or electronic scoreboard, etc.,
the captured image may flicker.
In this case, try changing the exposure mode to [Auto (Shutter-
priority AE)] and then select a shutter speed lower than 1/100,
to see if the situation improves.
