Depress the mode button (v) until (v)
appears on the LCD panel.
In this mode, the flash will always discharge in
both dark and bright conditions. When a portrait
is taken with the subject in a backlight situation,
the front of the subject may be cast in shadow.
In such a case, use the Daylight-Sync Shooting
Mode (Flash-ON Mode) within the flash effective
range to take a picture. This will ensure that a
picture is well exposed without any shadow.
When you wish to discharge the flash, use this
mode.
Note;
• Make sure you're within the flash-effective
range even when you use the built- in flash as
a fill-in flash in daylight.
