[filmscanners] RE: PS sharpening



Of course, this is clear.
Applying GEM I somewhat sacrifice sharpness, so would try to recover at
least the appearance ...
The key is to figure out the "golden rule" to achieve the best trade-off
between the sharp appearance and grainless quality at high resolution.

Sharpening will not recover lost detail.  It only creates an illusion of
sharpness, and it is very easy to overdo, so beware.

Thanks, will look at it.
The sharpening I meant originally is intended to be implied on GEMed images
with high setting such as 3 and 4, since there is obvious sharpness impact
at this GEM settings.
Otherwise, I don't sharpen either.

Most people don't sharpen immediately after the scan (though some have
suggested an immediate MINOR sharpening to remove artifacts introduced by
the scanning process), so at 2900 dpi and 1000 dpi don't sharpen.

When you are done with the image and it's ready for print or the web, then
you sharpen, and at that point it depends on the resolution of the image and
it's content.  I know of no set rules or guidelines.

Bruce Fraser has some excellent articles on sharpening at

Hi.
I would be interested to know how people use Unsharp Mask in PS to make the
images sharper, especially following high settings of GEM (produced by Nikon
IV ED)
I'm still trying to establish the range of best Unsharp Mask settings for
different cases (scenic, portraiture and other kinds).
Let's assume the scanning resolution is 2900 dpi  and 1000 dpi.

Regards,
Alex Z
