This command could be an ideal solution in the following scenarios:
| • | For photos that most likely contain excessive noise (such as a video whiteboard capture), using the command with low settings can help make the overall image clearer without excessive blurring. |
| • | For photos taken with normal settings, this command is best used only on key areas needing correction, such as image artifacts surrounding the subject area. |
| To remove digital noise quickly |
|
| • | Choose Adjust  One Step Noise Removal. |
| After a brief pause, the noise is automatically removed. |
| To use advanced options for removing digital noise |
|
| 1 | Choose Adjust Digital Noise Removal. |
| The Digital Noise Removal dialog box appears. |
| 2 | In the Remove Noise tabbed area, mark the Link detail sizes check box to adjust the Small, Medium, and Large settings in proportion to each other. |
| 3 | Type or set values in the Small, Medium, and Large controls. |
| These controls define the amount of correction to apply to small, medium, and large noise patterns. |
| 4 | Type or set a value in the Correction blend control to determine to what degree the corrected image will be blended in with the original. |
| The blending values range from 0.0 (no noise reduction) to 100.0 (full processing of the entire image). The default value is 70. |
| 5 | Type or set a value in the Sharpening control to determine the degree of sharpening, if any, to apply to the image after the noise reduction is applied. |
| The default value is 0. |
| 6 | Click OK. |
|
Unmark the Link detail sizes check box, and type or set values in the Small, Medium, and Large controls.

| To protect image areas from noise corrections |
|
| 1 | Choose Adjust Digital Noise Removal. |
| The Digital Noise Removal dialog box appears. |
| 2 | Click the Protect Image tab. |
| 3 | In the Before pane, pan and zoom as necessary so that you can view the region you want to protect. |
| 4 | Hold down Ctrl, and drag over the region you want to protect. |
| Note: Holding down Ctrl does not create a corresponding crosshair in the image window of the Remove Noise tabbed area. |
| 5 | In the Selected hue range group box, type or set values in the Hue and Range controls. |
| Note: The existing settings reflect the area sampled. You can manually adjust the hue knob by dragging it inside the ring. |
| 6 | In the Protect selected hue range group box, drag any of the seven graph handles downward to apply less correction and smoothing to the corresponding segment of the hue range. |
| For example, dragging just the middle graph handle to the bottom of the graph completely suppresses the midtone of that hue range. |
| Note: The graph handles cannot be dragged laterally. |
| 7 | Click OK. |
You can remove color adjustments for a selected color range by clicking Reset Current. To remove all color adjustments, click Reset All.
