Brenda,
Your "waffle effect" is known as "screening", caused by an interaction of
the original print process and the scanning process.

The solution is to rescan with a "descreen" setting. This is not offered by
all scanners/software, but you may be lucky. It may also be called something
different with your scanner so best read the manual.

As far as I can gather, descreening is more of an art than a science, unless
you happen to know precisely the dot-frequency of the original photos. I've
used it on a couple of occasions with varying success. You have to be
prepared to experiment until you find the right setting. The good news is
that, if all your photos are from the same book, the setting is likely to be
the same for all.

HTH
Adrian
