You can reduce noise that arises in RAW images shot at night or with a
high ISO speed.
NR is an abbreviation for “noise reduction”.
1 Select the [NR/ALO] tab sheet from the tool palette in
the edit window or edit image window.
2 Click the [NR Preview] button.
 The [NR Preview] window appears.
3 Adjust an image.
 You can set a noise reduction level from within a range of 0 to 20.
The larger the setting, the larger the noise reduction effect.
 The noise reduction effect can be checked when an image is
displayed at 100% in the NR check window.
 You can change the display position of the NR check window by
dragging the enlargement display position in the navigator
window.

4 Click the [Apply] button.
 Noise reduction is applied to the image and the image is
redisplayed.
Noise reduction cannot be applied when [Viewing and saving RAW
images]
(p.89) is set to [High speed] in the [Preferences] window.
Select [High quality] to reduce noise.
After selecting multiple images in the main window, you can set the
same noise reduction level for the images without displaying the [NR
Preview] window, by adjusting the noise reduction level in the [NR/ALO]
tool palette
(p.129) using the [Luminance noise reduction] and
[Chrominance noise reduction] sliders, and then clicking the [Apply]
button.
The noise reduction function does not work
To set the same noise reduction level for several images
 You can set the default noise reduction beforehand, using
[Default noise reduction settings] in the [Tool palette] tab sheet in
the [Preferences]
(p.92) .
• When [Apply camera settings] is selected, you can pre-set a
noise reduction level that suits the camera settings beforehand
as the default.
• When [Set as defaults] is selected, you can pre-set a preferred
default setting for the noise reduction level beforehand. This is
particularly useful for applying noise reduction to all the images
in a folder at once, such as batch noise reduction for images
with high ISO speeds.
However, for images with recipes attached, the noise level
recorded in the recipe will be applied.
 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 [NR Preview] window functions, see p.131 .
