thanks Gabriel, but I'm afraid the pitch will be crucial... once ago I
bookmarked a web page offering crops to hobbysts, but the pointer doesn't
work any more. (the either changed server or shut down).

I think I first will try this way...

yeah, but look at system needs: 128Megs RAM, twin HDs, Win NT... I should
upgrade my hardware and OS... provided I could afford the release! anyway
another source for links to software web sites is:
http://www.shortcourses.com/book03/lenticular.htm
and a cheap multi-interlacer is offered by  http://www.lexer.com/intro.html
... sorryly (for me) it works only on Mac!

I don't like conversion, even if I did some experiments of fake 3d
http://www.onelist.com/files/photo-3d/fake3d.JPG.
(curiousity kill the cat, but my skyzophrenia doesn't yet make me believe
I'm a cat...). I think I'll also try that freeware
Anyway my goal (for lenticulars) is to scan some of my Nimslo shots and
print them, before cropping the outer 2 to get stereo slides...
