* Exposure Warning
If the subject is too bright or too dark, the shutter
speed and aperture setting in the viewfinder blink.
When the subject is too bright, choose a faster
shutter speed. If it is too dark, choose a slower
shutter speed. When the shutter speed indication
stops blinking, you can take the picture. If both
selected shutter speed and aperture blink, it means
that the exposure is out of metering range, unable
to obtain a correct exposure even if the shutter
speed is adjusted. Select a darker subject if the
subject is too bright. Use a flash if it is too dark.
