IMHO - you're better off letting WM or someone do the work. It is quite
time consuming.

It is doubtful that any consumer film processor--such as Wal-Mart or
Walgreens--would scan your negs at high resolution.  In fact, the people
that operate those scanners will probably not even KNOW what resolution they
are set for.

I, too, have remained with my film cameras and lenses.  I take my film to my
local CVS pharmacy, where they develop and return the uncut negatives for
$2.50 per roll.  The process takes all of 20 minutes.  I wait for them at
the counter, rather than making a return trip.  Then I just take them home
and scan them myself.

The scan time is the problem.  It takes me 30 minutes to pre-scan the roll,
then it takes about 6 minutes per each final scan (when Digital ICE3 is
turned on).  So it takes between 2.5--3 hours to scan a roll, but I get
48-bit scans, Digital ICE3 cleaned-up, tiff format files that are 103 meg
each.

If you scan only a roll at a time it is not a big problem, but if you shoot
several rolls, the scanning times are burdensome.  My scanner can scan the
entire roll without intervention from me, so if I put in an uncut roll, I
can leave and come back in 2 or 3 hours and the job is done.  This is NOT
the case with mounted slides, which must be individually scanned.

You might check amazon.com for the PrimeFilm scanner series, as they are
priced low and some of them have Digital ICE3 (a must).  But if you are a
high-volume shooter you will find scanning to be a big drain on your time.
As I understand it, virtually all consumer scanners take a long time per
image.

Fortunately, I'm a "one-roll-a-week-man."  I can live with 3 hour scan
times--especially since I can walk away and let the scanner operate on its
own.
