Noise Removal options

Despeckle

Removes noise.

Square

Removes noise using a 3 x 3 pixel square.

Removes noise using a 3 x 3 pixel X shape. Use this option when you want to preserve an image's thin and

diagonal lines.

Plus

Removes noise using a 3 x 3 pixel plus (+) shape. Use this option when you want to preserve an image's thin,

vertical, and horizontal lines.

Hybrid

Removes noise using a 3 x 3 pixel square, a 3 x 3 pixel X shape, and a 3 x 3 pixel plus (+) shape. Use this

option when you want to preserve an image's thin, diagonal, horizontal, and vertical lines. When hybrid is

selected you have additional noise removal options:

Luminance: Drag the slider to the left or right to control variations in brightness.

Color: Drag the slider to the left or right to control variations in color (hue and saturation). For

example, drag the slider to the right if you want to reduce color variation. However, you should be

careful about reducing color variation (that is caused by noise) because you could unintentionally

reduce real color variations in a photo.

Reset

Discards all changes and reverts to the original noise level.

Batch Edit Sharpening Options

You can use the options in the Sharpening section to sharpen an image by enhancing the contrast of medium-contrast and high-

contrast edges.

To use the Sharpening options:

In the Batch Edit wizard, select the Sharpening check box.

Sharpening options

Amount

Specifies the amount of light added to or removed from each edge. Higher values produce darker edges.

Radius

Specifies the number of pixels to adjust around each edge. Higher values increase the number of

sharpened pixels.

Threshold

Specifies how different the lightness values of two adjacent pixels must be before they are sharpened.

Higher values increase the required difference. It is recommended that you set the threshold so that it

enhances edges while keeping background noise to a minimum.

Reset

Click to reset all options to the default.
