Hello all,

Well, I finally got myself an LS5000 with a slide feeder (yahoo!),
and I'm working on learning how to use it.  Autocropping is one of
the things I'm trying to figure out, as my first pass led to scans
with black edges.

Ed, do you have suggestions about where to start when you suggest
"try the various cropping options"?

Should I try to obtain 8.0.4?

Should I use the software bundled with the scanner instead of vuescan?

Does anybody else have some other ideas?

My solution was going to be to mess with the settings semi-randomly,
and if that failed to resolve the problem, simply accept the black
edges and crop them out later.

Thanks,

Carlisle
