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

message

 Noise reduction in progress... 

will appear with a relevant

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. We recommend disabling Noise Reduction to allow

shooting multiple frames in series and to apply noise reduction later

during the post-editing stage. The images will have to be taken in

raw data format.
