This may be a silly question, but I have an Espson 2450 and it is soft. The
4870 seems soft also. The review of the new Can*n flatbed said it is soft
compared to the 4000. The question is, if all the scanners require heavy
sharpening, what does the increased dpi really get you? I understand the
increase in Dmax is most likely important with the new scanners. It seems
to me that you can get a high quality flatbed and you have to sharpen a lot
or a high quality film scanner that really brings out the grain. When we
discuss these scanners are we really just discussing being able to print
larger? With 4000 dpi you can get a good 11x14 equal to an 8x10 on a 2800
dpi. It this too simplistic?

Reports on forums and personal experience with a Can*n 5000F.
Ed Hamrick just finished film support for the 5000F, so I had to try it
out. I scanned an old outtake slide from a graduation
<http://www.moosemystic.net/Gallery/Combo.jpg>. Be sure to view at 100%,
some browsers/settings will reduce it to fit on the screen. The bottom
row of samples are:
1. 5000F using CanoScan software at 2400 dpi, full pixel sample, no
processing.
2. 5000F using VueScan software at 2400 dpi, full pixel sample, no
processing.
3. FS2710 using VueScan at 2700 dpi, downsampled to same size as 2400
dpi scans. I think I sharpened this, not sure.
4. Scan #3 with grain reduction applied with NeatImage.
The 2 samples at the top are full pixel versions of #3 & 4 before size
reduction, so you can see downsizing hasn't changed anything significant.
As you can see, the Canoscan software gives a significantly less
detailed image with less contrast than VueScan with this scanner. Color
balance is off too and it crops the image on all sides. Oh, and takes
2-3 times as long to scan.

Thanks for the samples. I can't pick either one out as better than the
other. More grist for my decision mill.
