Wow, I would like to see it. Very early technology is most times very
interesting or nice.

My mistake - I was talking about better paper than the usuall news
rags. Of course grayscale newspapers are about 80 lpi screen. Though,
I _do_ think when I counted the part-colour part-grayscale dailies we
have (I _hate_ colour dailies - it takes out the seriousness... long
live FAZ!), I counted about 133 lpi in the colour photos and the usual
80 lpi in the grayscale. I will have a look at it again,... [away from
keyboard, measuring with my trusted Br�der Henn-Wien 50x typog loupe]
I found 5 dots per mm, equating ~127-130 dots per inch. That's about
the usual 133 lpi, or did I get something wrong? Its on normal
newsprint paper (though, what is "normal" news paper - this paper is
less rags more paper it seems than the usuall all-rags of 10 years
back), although looking a little better. Grayscale photos are still
~80 lpi.

Thanks!
When using only 1.5x resolution, is there much quality loss
visible (I know it depends on more factors, and even less
countable like author or viewer...)?
I ask because I fell in love with a S(Z)LR digicam, with only
1.5MP res - a Sony DSC D700 (Sony! Even more Off Topic! Sorry).
Even though I don't know how much it costs or costed (or even
how old is it)... manual zooming and 28-140mm/2-2.4 lens are
big pluses!
