NOISE REDUCTION
NOISE REDUCTION FUNCTION FOR LONG-TERM EXPOSURE
In digital photography, the appearance of flawed pixels that can be
white, red, blue or green is referred to as "noise". Image noise be-
comes more apparent when using higher sensitivities, particularly on
uniform dark areas. 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)
automatically after a shooting with slow shutter speed and high
ISO value. The noise metered in this parallel image is then digitally
"subtracted" from the data for the actual image. In such cases the

time value. The doubling of the "exposure" time must be taken into
account for long-term exposure times. The camera must not be
switched off during that time.

NOISE REDUCTION IN JPG SHOTS
Except when high sensitivities are used, noise is luckily negligible.
Nevertheless, noise reduction is a component of data processing
when JPG files are generated. On the other hand, since it also has an
effect on the focus review, you can optionally weaken or strengthen
this noise reduction in comparison to the standard setting.
