southern MN | Wife deals with the moire pattern issue all the time at work.
You hardly ever see news people wear tweed on tv because of it.
Digital pics and many printed pics are made of dots in a line.
When there is a pattern of lines just slightly off in the pic material, they cause the weird moire patterns that form.
