Hi Ender,

I know know if you read scanning newsgroup? This question came up from time to
time. I don't think there is a definite answer to that because, as I have
said, continous-tone negatives is NOT digital negative with high resolution,
so we are comparing apples and oranges.

However, you can approximate some figure with the resolving power of the film
(or I think they have another term for film, resolving power might be for lens
and there is a compatible term for film). But that gives you an approximate
number only. It doesn't transfer directly to lpi.
