filmscanners: nikonscan

thanks to both Ralf and Bill Fernandez for their advices on nikonscan
both of their postings have been really useful
Ralf showing  how to use the histogram fully
Bill for his confirmation that the Nikon's colour profiles are wonky.

heres couple of my tips in case anyone out there needs them:

1: focusing: the focus point is moveable from its default position which is
right in the centre of the frame (often wrong as it's the high/ low point of
any bow) you can move it by switching on the focus point selector (rather
than the crop layout, in the layout tools tab) and then clicking where you
want it. or you can shift it at any time by holding down the shift key and
click the autofocus button on the main display, then click the point on the
image you want. This is useful to work around the image checking focus in
various places, and setting a good mid point.

2: Switch off the focus before scanning option (single scan in preferences).
it is enough to focus before preview, and if you should decide to manually
shift the point to some suitable balance between focus positions, then the
manual setting would be erased if you then let the machine re-focus at your
last point before scanning.

3: Turn off  ICE and GEM for previews. It wastes time and it stops you from
seeing any huge pieces of dust on the preview before scanning. which you
should remove rather than letting ICE cover it up.

4: Use super fine setting. It makes better scans. slower, but better.

5: As many others have said: turn down the analog gain for negatives. It is
set about right for slides, but way out for negs. Turn it down to about -.5
to -.9, to get the highlights into the histogram.  If in your histogram you
see the highlights drop right down to a single line that just seems to go on
forever, no matter how much you decrease the gain, then that is a specular
highlight (shiny reflection of the sun for example) that you will never get
in the histogram, nor should you try!

6: Try Vuescan. the color profiles, film selections and defaults are much
better than NS's. Do an Adobe RGB scan in NS and an Adobe RGB in Vuescan. a
shocking improvement. Unfortunately GEM seems better in NS, there's no
selectable focus position, etc. damn.
