I have a Canon FS4000US film scanner. Seems to work OK and has good reviews.
I am a little disappointed when zooming in on detail that it seems rather
grainy. OK I am zooming in a lot on distant faces but will a better scanner
give any improvement in results or have I simply got down to the film grain
(most films ISO 200 or 400) and thats the limit. Is there any technique I
can use or any software that will 'improve' the results i.e. less grainy and
more detail? Neatimage does a cracking job on grain but does not improve
detail. Unsharp mask simply accentuates the grain. I have tried multiple
pass scans but no noticeable difference (even up to 16 passes). Any advice
gratefully received

Film grain will show patterns. If it doesn't then you are looking at
the scanner "grain" or pixels.

If you've reached the limit for either the scanner resolution, or film
grain you can not really improve the detail. It can be done stacking
multiple images, but that's a different ball game.

My guess is you have reached one or both limits and you can not get
detail where there never was any.

Good Luck

Neither film nor digital has infinite resolution.
Before a digital image breaks up and pixellates as you enlarge a section it
seems "better" to many viewers because it appears to have less grain. In
fact, despite grain, the film image generally contains more pictorial
information.
Is a paradox.
Unless you are asking the impossible there are many techniques for treating
the grainy appearance of film.
Also there is a great difference between what you see in an enlarged section
of an image on your monitor and what a final print looks like. You may find
your prints look better than you think, especially if you do not print the
image too large.
