Epson V700, tests/reviews/techniques for best sharpness

[tinnews]

I have an Epson V700 which I am using to archive a lot of old
negatives and slides. The older ones are probably not sharp enough to
worry about to a huge extent but I'm now getting to newer, sharper
ones. (They're sharper because my cameras improved, not because of any
strange ageing process!)

I've seen a few reviews where the Epson software's dust removal seems
to worsen sharpness considerably and also some where using Digital ICE
seems to worsen it too.

Most of my slides are non-Kodachrome, a large proportion of home
processes Agfachrome and a few Ektachrome. Where's the best place to
start at least for best sharpness? (... and don't say a dedicated
slide scanner, I know that but it's not where I am)

Hi

when scanning at 4800 dpi I start out trying something like 200% , threshold
of 0 and radius of anything between 0.3 pixels and 1.7 pixels. Anything more
than that is a bit harsh for a overall sharpen and will bring out the grain
aliasing more. I've found that this brings it within ballpark of an
unsharpened scan from a Nikon

My V700 brings out grain in old AgfaChrome slides (CT18 I believe)
almost too well, Later AgfaChrome 100, Ektachrome (not 200) and
Kodachrome are fine. Sharpness hasn't been a problem with mine. There
is a UK photo mag on line (Photo-i ?) that goes through setting the
pins to change film holder height.
I only use Digital Ice when I have too since it does double the
scanning time. There is a slight loss of sharpness with DI but not
nearly as much as with the Epson despotting utility ( the Epson
utility is faster). I use Smart Sharpen in Photoshop, usually about
100 at .9.
I consider the V700 the best scanner for its price range. Almost as
good as the Nikon dedicated scanners, better than old Nikon scanners,
out did my LS2000 that had just come back from service at Nikon.
