To apply the Add Noise effect

1 Select the bitmap with the Pick tool.

2 Click Bitmaps, Noise, Add Noise.

3 In the Noise Type section, enable one of the following buttons:

• Gaussian — prioritizes colors along a Gaussian curve. Most colors added by the effect closely resemble the original colors. Use this option to increase light and dark pixels and produce a more pronounced effect.

• Spike — uses colors that are distributed around a narrow curve (spike). Use this option to produce a thinner, lighter-colored grain.

• Uniform — results in an overall granular appearance. Use this option to apply noise randomly.

4 Move the Level slider to set the intensity of the noise.

Higher values (set by moving the slider to the right) increase the intensity of the effect.

5 Move the Density slider to set the amount of noise pixels per inch.

Higher values (set by moving the slider to the right) increase the intensity of the effect.

6 Enable one of the following Color Mode buttons:

• Intensity — adds a significant amount of noise

• Random — creates noise using random-colored pixels

• Single — creates noise using the color you choose from the color picker

7 To add a randomly colored noise texture, enable the Color Noise check box.

• The Add Noise effect supports all color modes except Paletted and Black-and-White.

• You can also adjust the intensity and the amount of noise pixels per inch by typing values in the Level and Density boxes.

• You can also choose a color for the noise, click the Eyedropper tool, and choose a color from the image.
