[filmscanners] Scanning Shadows

["" <HMSDOC@aol.com>]

Beginers question here...

I just used my Canon FS4000 to scan a slide of a view of  trees in autumn
taken with a wide angle lens and looking upward with the trunks running from
top to bottom in the frame.  Most of the trunks are dark and the leaves well
exposed.  How does one deal with improving detail in the shadows or
underexposed region of a slide?

I would presume that the first step is to examine the slide.  If it is
exceedingly dark with no detail I presume that it is impossible to extract
detail.  What if it is underexposed, but some detail is still there...what is
the best way of maximizing the amount of detail in the scan and in subsequent
editing?

How much benefit would multi pass scanning in VueScan be...does this just
limit noise in dark areas or will it also extract detail?  What would be the
best way to deal with the image in an image editing program...try to mask out
the rest of the image and expand the contrast in the dark area?

Thanks .
