I like the explanation, Tony - a few pictures can be really helpful, which
is why some threads on this list take longer than they might otherwise.
:) One small niggle which may not be worth mentioning - AFAIK most film
scanners use a single row of CCD elements moved across the film or with
the film moved across the elements, rather than a grid CCD like in a digital
camera. So your grid pattern diagram shows the areas "seen" by the CCD
elements, not a grid of actual CCD elements. The net effect is the same,
so it may not be worth confusing people with.
Only pedants like me would point it out. ;)
