Reducing Noise
You can reduce noise that arises in JPEG and TIFF images that have
been shot at night or with a high ISO speed.
1
Select the [NR/Lens/ALO] tab sheet from the tool
palette in the edit window or edit image window.
2
Adjust an image.
O 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.
Drag the sliders right
3
Click the [Apply] button.
¿Noise reduction is applied to the image and the image is
redisplayed.
4
Display the image in the [100% view] or [200% view].
¿You can check the noise reduction effect.
O In the [50% view] or [Fit to window] display, it may be difficult to
check the noise reduction effect.
Because noise reduction effect is difficult to see in the [50% view] and
[Fit to window] displays, use [100% view] or [200% view] to check the
noise reduction.
To check the noise reduction effect, enlarge the image and
display it
O If [Luminance noise reduction] has been set, resolution may be
reduced along with reduction of noise.
O If [Chrominance noise reduction] has been set, color bleeding
may occur along with reduction of noise.
O You can set the batch processing settings for noise reduction
beforehand, using [Default noise reduction settings] in the [Tool
palette] tab sheet in Preferences (p.75). 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, where images have a recipe attached, the noise level
recorded in the recipe is applied.
O For a list of tool palette functions, refer to p.110.
