In the [50% view] or [Fit to window] display, it is difficult to check
the noise reduction effect, so noise reduction is not applied.
Additional information
The noise reduction function does not work
Noise reduction cannot be applied when [Viewing and saving RAW
images] (p.57) is set to [High speed] in the [Preferences] window.
Select [High quality] to reduce noise.
To check the noise reduction effect, enlarge the image and
display it
Noise reduction is applied when the image is displayed enlarged in
the [100% view] or the [200% view] in the edit window or the edit
image window. It is not applied in the [50% view] or the [Fit to window]
display or any other window as the noise reduction effect is difficult to
check.
If [Luminance noise reduction] has been set, resolution may be
reduced along with reduction of noise.
If [Chrominance noise reduction] has been set, color bleeding
may occur along with reduction of noise.
For a list of tool palette functions, refer to p.91.
