Here are some of the scans I promised.
I made them by attaching the scanner to another current outlet group, but it
did not change things. I also swapped the negative to show you the error IS
in the scanner, not the negative (largest yellow band still appears at the
Here they are in the http://www.bigfoot.com/~jerfi/testscannerfix/ dirctory:
The film scans were made using Vuescan 7.1.3, the newest version yesterday.
* the Vuescan settings to default,
* used a scan resolution of 675dpi and resampled the image to a
quarter its size (corresponding to 337 dpi) using Picture Window Pro 3.0.
The crop file was saved from Picture Window Pro as a jpg at 100% quality
The raw scan file was also downsampled using PWP and may as a result have
obtained a color profile (perhaps sRGB, didn't take the time to check that).
My mistake. However, you will still see the banding if you convert it to a
positive scan. BTW. the raw scan file is still in 16bit mode.
Now if you compare this to the flatbed scan from the print I received from
the printing service you know that the print shows much more color
information AND has no banding! Unfortunately, they just crop wrong!#$%

Except for the yellow bands and strange color I obtained a scan with a very
nice soft! grain pattern.

(also PWP'd and saved at 100% jpg quality)
So is it user error, is it scanner error (bad lamp / bad CCD) or is it me
pushing the envelopes of what a decent scanner can do?
Thank you all for your interest, I've used you comments to make my point at
BTW. All good intentions and manners aside: Mr. Honda Lo has become very
silent for weeks now. The same goes for the dutch contact person, whom I've
mailed several times (always received a return receipt, but unfortunately
that does not prove much). I am getting frustrated enough to write to the
bosses / managers / colleagues of this dutch contact person (whose email
addresses I got from Mr. honda Lo), just not there yet and still hoping for
some help from Acer NL. Are they just waiting for my 90 days warranty over
the previous repair to pass?
This mail is Bcc'd again to both Honda Lo and the dutch contact person.
