Adding Noise

You can use the Add Noise tool to add a grainy texture to an image. Adding small amounts of noise can reduce the appearance of minor imperfections in the original image.

You can save your settings as a preset for future use.

To add noise to an image:

In Edit mode, in the Detail group, click Noise.
Select the Add Noise tab.
Set the options as described below.
Do one of the following:
- Click Done to apply your changes and close the Add Noise tool.
- Click Cancel to discard all changes and close the tool.

Click Reset to clear your changes and reset to default settings. If you saved your changes, you cannot reset your settings.

Add Noise options

Intensity	Specifies the amount of noise to add to the image. A higher intensity increases the chance that a noise pixel will replace a pixel in the original image.
Color proximity	Specifies the color of noise pixels to add to the image. A lower value gives each noise pixel a color similar to the pixel it replaces. Higher values result in a random selection of the noise pixel color.
Noise color	Select one of the following options to specify noise pixel color: Random: Randomly selects the color. Monochrome: Produces black and white noise pixels. Adjustable: Randomly selects the color of each noise pixel, but more pixels match a defined color. To define a color, click the color picker and select a color.
Noise placement	Adds noise to image areas that closely match a defined color. Select the Set color check box to enable noise placement, and click the color picker to specify a color.
Randomize	Indicates the random placement of noise in an image. When you use Add Noise tool, ACDSee places the noise pixels based on a random seed. This makes the image noise different each time you use the Add Noise tool. You can define a specific random seed to generate identical image noise. To generate a new random seed, click Randomize.

You can right-click a slider to reset to the default value.

You can use the Edit Brush to paint this effect onto specific areas of your image.
