I used to think that I was not getting Newtons Rings with my B&W scans but
when I looked more closely I often was.

All gone now with wet mounting but I realised that it was that the rings
were just that much more obvious with colour material.
Without wishing to state the obvious, in colour the fringing is muticoloured
in B&W just light and dark.

There may also be differences in the emulsions, I know there has been debate
elsewhere about dust clinging more readily to B&W sheet film than colour,
perhaps differences in static between emulsions govern how closely they
cling to a scanners glass ?

so what do you use to wet mount?? all that cleaning up?? I've just done
another patch of tests - this time scanning an unexposed neg, so all I get
is grain. Absolutely no rings on BW, but colour... can't use it.

For wet mounting I use Kami 2001 scan fluid, but you are right about the
cleaning up and it is slower but no rings. Also images do appear sharper.

Has anyone actually tried this stuff instead of glass and/or mounting fluid?

with what results?

Tim,

I have used the Ultrabase with my Linoscan 1400 with 4x5 negs and it seems
to work fine in terms of no Newton rings. I do wish it was a bit heavier
though. I am not certain it has enough weight to get the neg perfectly flat.
Very convenient though.
