Nothing magic about the plastic film scanners, the purpose is to just give a flat surface that holds the film just off the glass. Thin black cardboard, cut as needed, works great. Even heavy construction paper, you just need the film not contacting the glass or you get Newtons Rings on the images.

It has a second light source, intended to sit above 4 35mm slides arranged in a square, for scanning. I discovered that if you remove the slide holder, this second source is the right size for acanning glass negatives. I also discovered that the film (as opposed to framed slides) holder can take archival film (which can be a metre long). What I do is have the roll of film on one scide of the flatbed, and another spool (the centre tube from a toilet roll works fine) on the other side, and gently pull the film through the holder, winding it onto the second spool. I normally wear cotton gloves to protect the film (any decent photographic shop should have them, I also take them to archives when I expect to handle old papers). Hp haven't made or sold this scanner for some years, sadly, so the second hand market is the only option. Lesley Robertson
