What drum scans need is a lot of post-production for cleaning-up the images.
It's not just dust but any number of problems with air bubbles and the optical clarity of the top sleeve used to hold the whole tranny / neg sandwich together.
In fact how many different surfaces are there when using a drum scanner?
For a fact, most hi-end drum scanning services spend up to 15 minutes 'retouching' your image before you even see it...

Dear Michael
Drum scans shouldn't need cleaning up. The ICG drum I mentioned to Richard creates what amounts to two surfaces, the wet front of the film and the optical glass outside. There is no clear film layer and the oil is spread very thin by the centrifugal force.
How clean are your transparencies you send for scanning? Mine are cut from the sleeves the E6 lab provides and sent straight to the scanner in that form. Nothing, and I mean nothing, comes into contact with the film.
The price I am paying for scans no one could afford to spend 15 minutes cleaning them. I've seen 5 drum scans produced in less than 15 minutes that were perfectly clean.
