I wonder if its possible to make a scanner use a larger transparency
adapter than the manufacturer intended.
The adapter merely provides a different (transmitted) light source rather
than the scanners internal source for reflected light.
We have a small epson transparency adapter. Out of curiosity I took it
apart. All that is inside is a very small lighting filament and a set of
reflectors and diffusers to provide a diffuse even lighting.
If one could determine the approximate lighting level, and get the scanner
mechanism to travel a greater length in transparency mode it might be
possible to get a scanner to do big transparancies.
Who wants to do experiments with their expensive scanner :)
