would be the existence of any adhesive labels attached to the slide mount. This would
cause the mount to be slightly thicker on the side with the label affixed.
The Mount Type
Plastic, cardboard and glass mounts are commonly used to frame film. Typically,
the plastic and cardboard mounts center the film in an open window. Thus, the light
passes through the air on both sides of the film and through the film. When the film is
mounted in glass, there is a thin piece of glass sandwiching the film as shown in Figure
4.17. Glass mounted slides are «of recommended for scanning because they tend to dif­
fuse the image sharpness and they accumulate dirt and dust. In the case of a glass
mount, light must pass through the air, film and both sides of the glass. If you must,
you can scan a glass mounted slide whose frame thickness is less than 3mm, however
this will require use of the manual focus wheel to achieve optimum focus.

The Film Location in a Mount
Many film types are commonly used today. The film material and film thickness
of, and dyes and emulsions used on the film can affect how light passes through the film
and consequently the focus. In some instances, film will not be positioned in the center
of the slide mount due to labels being attached to the slide mount. It is important to
remove any foreign matter from the slide mount, if possible, before scanning.
