Removing Moire Effectively - Page 5
Change the mode of the copied file to “Lab Color”. This is found under “Image>Mode”.
Return to the original file and change it to Lab Color as well. (This can also be done after using the Moiré Eraser if you prefer.)We need to eliminate the color moiré in the original image. There are a variety of ways to do this. The cheapest way is to blur the “a” and “b” channels using Gaussian Blur. You will need to have the area with color moiré selected. Use whatever selection method is most convenient.
The “a” and “b” channels contain all the color information, so blurring them will eliminate the color moiré. Since the “L” channel contains the luminance information, the image will still appear sharp.
