Trouble with Nikon 8000 tray

[romeo]

I'm having problems with my 2 1/4" tray, especially made by Micheal
Greco. Won't get excepted by the scanner. Nikon tray works, but slides
are soft focus on sides. Greco's tray worked before, but stopped now.
If you can help in anyway--"We'll be friends forever more".

TIA

I'm not familiar with Michael Greco trays but soft focus around the
edges of mounted slides (if your focus point is in the middle) is
quite "normal" for Nikon scanners. The scanners have a very narrow
depth of field (fast lens) so focusing on warped mounted slides is a
nightmare.

The best you can do is move the focus around to several points in the
image where the most interest is and then average out the results. I
find that anything within +/- 5 "clicks" is largely in focus.
Depending on your requirements you may want to decrease this range to
+/- 3 for more accuracy. The best is to perform some tests and see
what looks good to you.

For what is worth my severely warped cardboard mounted Kodachromes
vary the focus by up to 25-30 clicks (in extreme cases) between the
middle and the outer edges of the slide. Flexing the frame can
sometimes improve things a little bit.

Anyway, what are Michael Greco trays and how do they improve the
focus? (I have an LS-50 if that makes a difference.)

Michael Greco trays--(which probably aren't his anyway)---cost about
$500 extra and are fluid mount glass trays--come to find out -- are
just nikon trays with some plastic cut out.---but they help sharpness
when they work.

I see! Thanks. Good to know, even though $500 is a bit steep.
