Under certain conditions, noise reduction will always be active as
long as the function is enabled. That includes shots taken with the T
function, as well as long-term exposure frames with shutter speeds
of ≥ +8 s.
In all other cases, noise reduction depends on a combination of fac-
tors (specifically ISO setting, exposure time, and sensor tempera-
ture). The following table contains a list of shutter speeds typical for
a sensor temperature of 25°C, at which noise reduction would be
applied.

Shutter speed longer than
100
200
400

Noise Reduction can be optionally deactivated (see p. 76).

The brightness of the screen image mirrors the effects of the select-
ed exposure settings when pressing and holding the shutter button
on the first pressure point. That allows an assessment the effect of
the relevant exposure setting on the image before taking the photo.
This will apply as long as the subject brightness and the set expo-
sure don't result in excessively low or high brightness values.
This function can be disabled for the manual exposure setting (M).
