[filmscanners] RE: Scanning old Lantern Slides



John,

It is not an impossible task; but I think due to the thickness of the
lantern slides, you will need to use a flatbed with a transparency adapter.
The key question will be how big the intended enlargements and prints are
desired, which will indirectly impact on the amount of optical dpi that will
be needed.  Typically, I think that 1200 optical dpi should be sufficient
with interpolation used sparingly when needed if large enlargements are
desired or if large amounts of cropping is used.  Given what I assume to be
the general quality of those types of slides, I do not think they would
suffer from limited interpolation.  The Agfa T2500 would be nice; but it
might be overkill in terms of price and absolute requirements.

Laurie,

Thanks for your input. Some of these problems do exist. But there is always
Photoshop to help correct these issues. In fact some of the lantern slides
are cracked, so this will definitely be a Photoshop task.

Regards,

John
