The problem with Kodachrome is the same as it is with B&W negative film.
The sensitive emulsion contains a large amount of silver and this
materiel does produce something when scanning with IR, unlike it is done
with conventionnal C41 or E6 emulsions.
Nikon has apparently solved the problem with the latest Coolscans, but
one has to investigate how.
