Dear Robert,
Yes you do see the grain in the highlights when scanning negs -- typically skies.
However, I use color negative materials and I have the ability to create easy masks (example: the sky) to soften such grain.
This is a common complaint with scanned negs. My theory is that somehow force-fitting chaotic silver patterns into an artifical scanning matrix leads to exaggerated (attenuated) grain. Over- (as well as under-) sampling seems to bear this out, but results in huge file sizes. Assuming this is 35mm, then oversampling at 8000dpi would allow you to downsample it to 4000dpi and I'd be willing to bet that much of the noise would be reduced. You might find it acceptible, I suggest giving it a try.
Cheers

Is anyone getting good results from drum scanning negatives? I have avoided it because I figured that while it works perfectly that grain=highlights=white (nothing) on paper scanning a negative would mean highlights=thick gobs of grain in a scanned negative.
Do you not get grain in the highlights from drum scanning negatives? I have a ton of tri-X that I would love to digitize at the negative stage.
T I A for your advice,
R

Considering the
qualities of this image, it might pay to get a truly professional 16-
bit drum scan from the neg; it may get more detail out of these dark
parts of the negative.
