[] Flicker
You may notice flicker or banding in the monitor during live view or when shooting movies
under certain types of lighting, such as fluorescent or mercury-vapor lamps. Flicker and
banding can be reduced by choosing a Flicker reduction option that matches the
frequency of the local AC power supply (_ 170).
[] Exposure
Depending on the scene, exposure may differ from that which would be obtained when live
view is not used. Metering in live view is adjusted to suit the live view display, producing
photographs with exposure close to what is seen in the monitor. In P,S,A, and [] modes,
exposure can be adjusted by +5 EV in increments of 1/3 EV (_ 70). Note that the effects of
values over +3 EV or under -3 EV can not be previewed in the monitor.
[] HDMI
When the camera is attached to an HDMI video device, the
camera monitor will turn off and the video device will display
the view through the lens as shown at right. If the device
supports HDMI-CEC, select Off for the HDMI > Device control
option in the setup menu (_ 148) before shooting in live view.
