* Exposure Warning
If the subject is too bright or too dark, the selected
shutter speed will blink in the viewfinder and on the
LCD panel as a warning as shown. When the sub-
ject is too bright, choose a smaller aperture, if avail-
able; when it is too dark, choose a larger aperture,
if available. When the shutter speed indication
stops blinking, you can take the picture. If both
shutter and aperture blink, it means that the expo-
sure is out of metering range, unable to obtain a
correct exposure even if the aperture is adjusted.
Select a darker subject if it is too bright, or use a
flash if it is too dark.
