Selecting a search
program
To select the appropriate search program:
1. Look at the film to see which channel(s) contain(s) image marks.
2. Determine the size(s) of image marks on the film.
3. Determine whether the film format is:
Simplex images are commonly
reduced to approximately 1/24 of
the original size; only one image
appears across the width of the
film.
Duplex images are commonly
reduced to approximately 1/40 of
the original size; the front and back
of the same image appear across
the width of the film.
Duo images are commonly
reduced to approximately 1/40 of
the original size; images are filmed
to the end of one channel, then
other images are filmed on the
other channel.
