"light eroded" slide scans with canon scan 8000F

Hi NG,

the link below shows a 100%-crop of a medium format slide scan which I have
scanned with parameters:

Film type: Provia 100F in a glasless gepe frame. The frame was put on top of
the glass without any slide holder.
Resolution: 2400 dpi
Sharpening: off
Dust Removal: "Normal" grade
Color depth: 8 bit

you see three light dots with some kind of halo at locations where the
original slide has very low density i.e. is very light, such as the light
reflection on the metal spindle. The scanner seems not to cope right with
that regions, it looks like the slide is punched at that spots.

Does anyone know this effect? Does it has something do do with the FARE dust
removal? Maybe it is a question of configuration of the scan software?

I think about buying the canon scan 9950F but if that scanner would show the
same odd phenomenon, it would be a bad decision.

Does it has something do do with the FARE dust removal?

Have you tried scanning without FARE? To me it looks like something is
filling in the highlights, as if it were defects.

Bart,

It seems to be the FARE function. I bought an epson 4990 today and the "dust
removal" (not digital ICE; epson offers both) function produces the same
effects.

I understood dust removal / FARE works software based without IR scan? It
seems not a very good function to me.
