[filmscanners] RE: Black and white scans onLS4000EDandotherissues



Austin,
You assume that everyone with a Nikon scanner has depth of focus issues.
But not me nor the three others that I personally know who use them.  No
depth of focus problems.  I am not saying that there isn't an issue with
depth of focus, but that some units(or maybe we just have flat film)do
not exhibit the problem.

Well, it has been well proven that you can get the same density range
from
the same negative with a cold light or a point light source, using
appropriate exposure time, aperture and grade of paper (or filter), so
that
is a non-issue.  The other issues are the "Callier effect", sharpness,
dust,
scratches and tonality (dynamic range).

What about the limited depth of focus, as well as scratches and dust?
How
do you compensate for that?

> Not sure if depth of focus is of any real relevance.

Snark, snark...ask people who own Nikon scanners if depth of focus is an
issue or not ;-)

Understood.  Me too.
