Re: Proposal for Scanner Comparison

The majority of my experience is in using the SS4000+ with slides.  I
have noted that the results are not as effective with negatives.  Then
again, I have yet to find the results of any scanner I have used as
effective with negatives, in spite of what others experience.  However,
having said that, I did find the SS4000+ better than the others with negs.

In terms of slides, both the SS4000 and SS4000+ have a long reputation
for quality results.  I can only assume your experience is due to a
defective unit, or some problem with software.

In regard to Insight, as you probably noted, it can be set to imbed a
color space, such as Adobe 98, and this is what I have done with my
versions, and as a result, the image in Photoshop looks identical to how
it appears in Insight.  Also, you have a method of altering the gamma
for Insight to represent you monitor.

I only have my monitor calibrated to Adobe gamma, and beyond that I use
   CMYK  as the input to the Epson printers, and use ink calibration to
get the printer to reproduce the screen colors.  It is probably rather
of an unconventional approach, but it works for me.  This closed loop
method works within my system, although I'm sure it could cause problems
if others used my files.  Images needed externally go as RGB files most
of the time.

I suspect you will find the Canon FS4000 more disappointing than the
Polaroids, but who knows.  The Canon has a much more limited dynamic
range than the SS4000+.  This might mean you have to save your pocket
change for a Nikon, or beyond.  But, you'll have to decide what works
best for your applications.
