Scanned two pictures of my Great-Gransfather and Great-Great-Grandfather and I see squiggly lines through the picture. These were copies of the original I scanned. I scanned at 300 DPI as both a photograph and document with the same result. I cannot see these lines in the original. Could this be an artifact of the scanning or something else. Not the best scanner in the world but never had this occur.

Thanks for any help.

Looking at D/L of the originals shows a very obvious surface patterning on original photos which would account for moire. Plus a horizontal "bar" effect from scanner strips not quite aligning. Older, well-worn machine?

Not really. Only about six months old, but not photo quality. Have one I will try first opportunity. Not sure if these photos were copied at a lab or printed by someone. I just wanted to make a digital copy to preserve them. Worse case scenario I will take digital photo and save.

I thank everyone for their help in this matter.

Turn the dithering feature off.

Sorry I had to leave quickly....The scanner software should have a checkbox or another way of allowing the scanner to use de-screening. This smooths out the photo and doesn't read all the dots from printing.

Like in a Flash Gordon comic strip. :D

How about taking a picture of the picture rather than scanning? That should work.

the suggestion to photograph the photos is a very good one and one I always use since I had problems with scanning much like you.

Here are two of the same images. One is scanned with the de-screening off and the other on. You may have to download them.

Looking on my iPad, I'd say the bottom one is the better of the two.

Agree, top shows a pattern throughout while bottom is smooth.
