Clear plastic sheets, often used for school papers and other small
reports, come in many colors. The yellow ones, and sometimes blue ones,
can help clear up microfilmed copies of documents. I think they work by
cutting down on the background, but the do work. If you have a poor
copy or a copy of a difficult document, try it-the sheets are very
inexpensive. You just put a small piece of the material with the film
in the holder-obviously you have to move the material for a different
frame.
