Distortion of lines on some portraits


I took some important pictures with a Fuji S602 digital and one of the subject's suits had tiny vertical lines in the weave. The results were areas of large swirls and exaggerated appearances. We used Adobe Photo Deluxe 4.0. but did not have very good results. Note that I took these on high resolution 2048 X 1536. Can someone tell me what caused the distortion and what to do about it? I haven't read of others having this problem. Thanks.

This is a moire' affect that distorts lines. I also used a Fuji S602 for years and I will even get that effect on occaision with my Canon 40D.
Alan may have the more technical reasoning behind why this occurs but I believe it is simply a transference problem recording an image with fine lines that causes this.
I took an image with this effect that even my eyes were seeing the moire' and was happy my camera was able to record the image the way I saw it. see pic...

But is is usually when you dont want it that you will get the effect.
