When the moon hits your eye like a big pizza pie, that’s a moirĂ©.

Question:
How do I get rid of that pattern on my image when I scan from a book or the newspaper?

Answer:
The pattern is called a moiré. It is the pattern presented when angles are scanned into the linear digital world. Shingles on houses were the first to be noticed.

Solutions:

1. Check your scanner. There should be rescanning preferences for printed material. There is a difference between newspaper and magazine. Before you scan, check the preference and set accordingly.

2. After you scan a printed image, go to the blur filter and choose Gaussian blur. You will have to adjust the effect several times to get the best results, but it will blur the dots and keep the image.
