Auto Tab Sheet


The Auto tab sheet features two automatic denoising buttons and various preset controls.


Auto Sample

When clicking the Auto Sample button NoiseControl tries to detect a valid sample area, which is used for adjusting the denoising parameters on the Manual tab sheet (except the Intensity slider of the Luminance Denoising group, which is not changed). In depends on the selection on the arrow button menu if the full image is searched, a 50% sized-down version of it or only the preview. Searching the preview produces the fastest, but least accurate results. Searching the full image is a more reliable method, but also takes more time.

After you clicked the Auto Sample button or selected one of the arrow menu options, the Next button is enabled. Clicking the Next button searches for the next best sample area. So if you are not satisfied with the results of the first sample area, you can click the Next button again and again until you are satisfied. If no more sample area can be found, the Next button is disabled again.

In rare cases this feature will not be able to find a sufficient sample area. Then try one of the other options on the arrow menu. In the case of the Preview option, you can also try enlarging the NoiseControl window, changing to 100% zoom or scrolling the preview.

Sometimes you may not be satisfied with the results of Auto Sample. Then you should try drawing a sample area yourself with the sample tool. You can also manually adjust the controls on the Manual tab sheet. This is especially recommended for very strong noise.

You can make NoiseControl trigger the Auto Sample feature on startup by choosing the Auto Sample option on the Prefs tab sheet.


Auto Preset

The Auto Preset button selects a matching preset from the preset list below. It extracts the camera model and ISO value from the EXIF data to perform its task. At the moment EXIF data are only supplied by Photoshop, Photoshop Elements and Photoline, so the Auto Preset feature will very likely not work if you run NoiseControl with another application. If you are not satisfied with effect of the chosen preset, try other presets in the preset list.

NoiseControl already contains generic presets for various general types of cameras. But it is more effective if you create your own presets for the camera(s) and ISO values that you are using. You can create the settings for these presets, e.g. by using the Auto Sample button, the sample tool or by manually adjusting the controls on the various tab sheets. Clicking the Auto Preset button acknowledges these self-created presets a higher priority and automatically select them if their file name contains a matching camera name and ISO value. See below on how to save your own presets.

You can make NoiseControl trigger the Auto Preset feature at startup by choosing the Auto Sample option on the Prefs tab sheet.

Preset Options

The Preset List

The main part of the Auto tab sheet is occupied by a list box with available presets. 21 general presets are already built into NoiseControl. Additionally you can save your own more specific presets, which will appear at the top of this list if you saved them in the default Presets folder. When you choose a preset from this list box, it is immediately applied and changes all settings.

The Preset Combo Box

This combo box contains three options: "Show All" displays all presets in the preset list box. "Own" shows only your self-saved presets. "Included" makes only the built-in presets appear.


Clicking the Open button displays a file dialog for selecting and opening a preset file. This function is only necessary if you did not save a preset in the default Presets folder of NoiseControl, because all presets of that folder are already displayed in the list box and can be opened by clicking them there. The folder of the last opened preset is displayed by default in the file dialog.


You can save the current NoiseControl settings as a preset with the help of the Save Preset menu item. The following folder is automatically displayed when clicking the Save button unless you just saved a preset in another folder:

Windows 2000/XP:
c:\Documents and Settings\<user>\Application Data\ThePluginSite\NoiseControl\
Windows Vista/7: c:\Users\<user>\AppData\Roaming\ThePluginSite\NoiseControl\

MacOS X: /Library/Application Support/PhotoWiz/NoiseControl/Presets/

Please save presets into this Presets folder, otherwise they will not appear in the preset list box. You can open a saved preset again by clicking it on the preset list box or by using the Open button.

If NoiseControl is able to access the EXIF data of an image, it automatically suggests a preset file name that contains the camera name and ISO value. Please accept this name if you want the preset to be selectable by the Auto Preset button.
