Reduce Noise

The Reduce Noise filter can be used for noise reduction as well as for smoothing out JPEG artifacts. To use the filter:

Step 1. Choose Filter>Noise>Reduce Noise.

Step 2. Zoom the preview image to get a better view of noise. Be sure to view the image at 100%.

Step 3. Adjust the following options:

• Strength: The amount of luminance noise reduction applied to the image's channels.

• Preserve Details: This preserves edges and image details such as hair. A value of 100 preserves the most image detail, but reduces luminance noise the least. You'll need to play with the balance of Strength and Preserve Details to fine-tune noise reduction.

• Reduce Color Noise: This removes random color. Use a higher value to reduce more color noise.

• Sharpen Details: This sharpens the image. Removing noise will reduce image sharpness.

• Remove JPEG Artifacts: This removes blocky image artifacts step and halos caused by JPEG compression.

Step 4. If noise is more prevalent in one or two color channels, click the Advanced button. Now you can choose individual color channels from the Channel menu. Next, use the Strength and Preserve Details controls to reduce noise in the problem channels.
