Transcript:Remove Photo Grain in Photoshop

Hi, I'm Don Schechter for About.com Computing. Today I am going to show you how to remove noise in your digital picture using Adobe Photoshop CS2. There is one filter that makes this really easy to do.

Open a Picture

• OPEN Adobe Photoshop
• CLICK File / Open
• SELECT Picture
• CLICK Filter / Noise / Reduce Noise

Preview and Zoom on Grain Changes

• CLICK on the preview box on the top right to see changes as you make them
• CLICK on the little plus size to zoom in
• CLICK and DRAG to move the picture around

Photoshop Noise Reduction Sliders

There are four sliders (on right) that you need to play with to reduce some of that noise:

• The strength controls the amount of luminance noise reduction.
• The preserve details slider adjusts image details like hair. A high value preserves the most image detail but doesn't reduce the noise as much. A big part of reducing noise is balancing the strength and the preserve details slider.
• The reduce color noise controls remove any random color pixels you may have.
• The sharpen details slider sharpens the image.

Photoshop Noise Reduction and JPEG Artifacts

• CLICK to Remove JPEG Artifacts box (if picture is low resolution.)

Photoshop Noise Reduction by Channel

• CLICK Advance button.
• CLICK Per Channel Tab adjusting strength of each channel red, green or blue
