(may vary depending on ISO sensitivity), those not available
appear in gray.

Notes
• In each of these cases, the exposure meter remains deactivated;
after shutter release, however, the digital number display in the
viewfinder counts the elapsed exposure time in seconds.
• Long exposure times may cause severe image noise. In order to
reduce this annoying phenomenon, the camera will take a
second “black picture” (taken with the shutter closed) automati-
cally after pictures taken with slow shutter speeds and high ISO
values. The noise metered in this parallel picture is then digitally
“subtracted” from the data for the actual picture. In such cases
the message
Noise reduction Noise reduction
will appear with a relevant time value.
The doubling of the “exposure” time must be taken into account
for long exposure times. The camera must not be switched off
during that time.
