[filmscanners] Why this horizontal line pattern in my "night shot" scans?

["Titus Tucan" <titust@sympatico.ca>]

Hi everybody,

I've scanned a 35mm slide, a night shot, on my Scanwit. In the lower part of
the slide where it was supposed to be black or almost black I got a pattern
of horizontal lines as seen here on my web site

I have tried the Scanwit software MiraPhoto and Vuescan and got the same
results. Looking at the slide trough a projector, there is no trace of
theses line.

Recenty, I went to my photo shop to scan another Velvia night shot MF
(6x4.5). They used a Nikon 8000 and ICE.
When I went to pick up my CD and checked the file, the whole slide had a
similar horizontal line pattern from scanning:

I complained and they scanned it again for me. The second time it was
perfect. !

Now here comes the question?
What is happening with these patterns and how did they get rid of it on the
Nikon 8000.

thanks a lot,

Titus
