while the displayed compensa­
tion amount is still blinking, the
flash exposure will be compen­
sated according to the compen­
sation amount.
If the subject Is very small and the background is very dark or far away, proper
flash exposure may not be achieved even if flash exposure compensation is
used. In a situation such as this, use manual flash.
