[filmscanners] RE: Advice on scanner settings

["LAURIE SOLOMON" <LAURIE@ADVANCENET.NET>]

As for output, TIFF is better than JPEG in most cases.  The resolution
sounds about right for 35mm slides as long as it is an optical resolution
and not an interpolated resolution. When you speak of three samples, are you
referring to three passes? Three passes is good in that it will enable you
to obtain a broader density range with more detail in the highlights and
shadows that might be lost with a single pass.

The Kodachrome may present you with some problems for a number of reasons
having to do with the nature and features that differentiate it from
Ecktachrome films.  If you mean what I think you mean by a "light infrared
screen," this may present some problems with respect to scanning Kodachromes
since they are based on a silver halide based process and not a dye based
process like Ectachrome and infrared does not penetrate silver very well -
if at all.  This is especially the case if screen is hardware generated and
not software applied.  If you are talking about a screen provided by
Vuescan, it is probably software based.

Bunch,

I about to begin scanning a lifetime of slides (mostly Ektachrome but
a smattering of Kodachrome) using a Nikon LS-5000 and Vuescan.

Are the following settings appropriate?  Why or why not?

I'm planning on 4000 dpi for maximum resolution, with 3 samples and
the color analog gain set at 1 for all colors.

I'm also planning a light infrared screen with no other filtering
with respect to colors, grain reduction, or sharpness.

I'm planning to auto balance colors using the default options and
appropriate slide types.

With respect to output, I gather that TIFF is better than JPEG,
because JPEG is compressed.  Is that right?

Thanks for your input,

Carlisle

--who figures he'll start scanning now, then figure out how to
manipulate scanned images later.
