The basic Sharpen/Noise tool provides controls to adjust the sharpness and the digital noise in the image. This tool includes a magnification viewer that shows pixels magnified up to 400 percent. The position of the magnification field is controlled by clicking the Magnify toolbar icon and then clicking inside the image.

For more information about sharpness and noise reduction, see the Understanding Basic Image Editing Tools topic.

To set the crop and rotation options:

1. | From the Tools menu, click Basic.

2. | In the drop-down menu, click Focus - Sharpen - Noise.

3. | To focus the zoom area on a specific section of the image:

o | Click inside the Zoom field and hold down the mouse key.

o | Drag the mouse in the direction of the area you want to view.

o | In the image panel, the yellow square identifies the portion of the image that is in focus in the Zoom field.

1. | To magnify the specified pixels in the Zoom field:

1. | To adjust the sharpness of the image pixels:

o | Under Sharpening, select the Enabled option.

o | Click on the Amt (Amount) slider and drag the slider to the right to increase the overall sharpness of the image and the contrast between neighboring pixels.

o | Click on the Sens (Sensitivity) slider and drag the slider to the right to set the pixel's sensitivity to sharpening. If the pixel falls below the sensitivity setting, the pixel is not sharpened. Use this control to block sharpenings to small noise patterns within the image. A value around 6 is recommended.

o | To turn off the sharpness controls without resetting the sliders, click the Enabled check box to remove the check mark. This tells Bibble not to apply any of the custom sharpness edits that you made to the image.

1. | To adjust the noise levels in the image:

o | Open the Fringe Reduction drop-down menu and click one of the pre-defined options. The Strong and Strongest fringe-reduction settings generate a smoother blend between pixels than the Standard option.

o | Under Noise Reduction/Smoothing, click the Noise slider and drag it to the right to remove pattern noise from the image. Dragging the slider to the left increases the contrast between pixels.

o | Click the Luma slider and drag it to the right to blur the distinction between neighboring pixels. Dragging the Luma slider to the left sharpens the image. Small values are recommended.

o | Click the Color slider and drag it to the right to reduce color noise between neighboring pixels. Adjusting the Color setting removes simple color artifacts; however, high values might cause a halo effect.

o | To turn off any of the noise reduction controls without resetting the sliders, click the check box next to the slider to remove the check mark.
