Sometimes, when you scan a photo, you’ll see a pattern over all the image. In order to correct this, you can try to blur the blue channel doing the following:
- With your image open in Photoshop, click on the Channel tab and click on the Blue Channel.
- Click on Filter, Blur, Gaussian Blur. The Gaussian Blur window is going to open; move the Radius slide to 2 or 2.5 pixels.
- You can blur the other channels also, but using lower settings.
- The image needs some sharpening at this point. Click on Filter, Sharpen, Unsharp Mask.
