*If an image is displayed enlarged, the enlargement display position can be moved by dragging. The enlargement display position appears when [Docking display] has been set and the edit image window has been enlarged. (Tool Palette)
Noise reduction cannot be applied when [Viewing and saving RAW images] 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 using the [Luminance noise reduction] and [Chrominance noise reduction] sliders, and then clicking the [Apply] button.
You can set the default noise reduction beforehand, using [Default noise reduction settings] in the [Tool palette] tab sheet in the [Preferences].
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.
