Noise means the rough texture that occurs in high sensitive photography. We call it high
frequency noise in the software.
At the high sensitive photography, red, green, or blue spots appear, too. We call them color
noise in this software.
The function to remove such noise is the noise reduction.
In this software, the noise reduction function has independent parameters for every category.
The following sections are summaries of the function of noise reduction.

The false color control function changes the process level of false color reduction.
The software enables one to reduce both false colors occur in the fine structure area (high
frequency area) and color noise.
When too much color noise at high sensitive photography or false colors in the fine
structure area occurs, increase the reduction level.
However, there are some limitations in this function.
As the reduction level becomes stronger, the color separation level goes down, which makes colors in the color boundary blur. Also,
there is a problem of "color spill," which is the phenomenon that occurs when the vivid color leaks around the picture.
Therefore, too strong reduction level may decrease the picture quality.

This reduces broader noise associated with high sensitive photographs and generates a
clean image.
This function reduces two different types of noise.
One is banding noise that runs horizontally or vertically. If you notice banding noise,
strengthen neat noise to adjust so that the banding noise will disappear.
The second are runs of color and brightness brought about by noise. If you notice runs of color or brightness, further strengthen neat
noise and false-color controls.
* Neat noise simultaneously performs processing in accordance with strength to remove banding noise and
processing to neaten runs of color and brightness.
Strengthening to remove banding noise varies only through neat noise parameters. Strengthening neatness of
runs of color and brightness changes both neat noise parameters and false color control parameters. (It is
determined by the product of these two parameters.)
Therefore, when adjusting neat noise, adjust false color control at the same time.
If you notice banding noise, first adjust so that it disappears using neat noise, then control runs with false color
controls.
If it is running colors and brightness, not banding noise, that you notice, first strengthen false color controls and
then adjust neat noise.
When adjusting parameters, it does not matter whether you first do neat noise or false color control, but it
becomes easier to drive parameters by using the above orders.
* The "Geometric NR" function provided in other versions (SILKYPIX Developer Studio 2.0, 3.0 and SILKYPIX
Marine Photography 3.0) was integrated into neat noise.Neat noise automatically processes "Geometric NR" if an
image taken by a camera that requires "Geometric NR" processing is being processed.
* Neat noise operates as "Geometric NR" provided in other versions if development parameters are in
interchangeable mode. Please see "4.17.2 Interchangeable Mode" concerning interchangeable mode.

Use the "Noise reduction" slider in the "Noise reduction" sub-control to reduce the high
frequency noise. This function reduces the noise, with using RAW data.
Also, you can remove noise that often occurs when the sharpness is increased. Use the
