>>3822590>@ 3200dpiAre you sure about that?
1800dpi, 3600dpi, 7200dpi are actual hardware resolutions. The intermediary ones are interpolated by the closest hardware resolution lesser or equal to the one you chose - at least in Silverfast. I don't know about Vuescan's drivers, but try 3600dpi to check, cause if you chose 3200dpi there's a chance you're actually scanning at 1800dpi.
Other than that, "raw" scans need some moderate amount of sharpening when viewed at 100%. Most software does that automatically, even professional scanners, and some times it's a proper bitch to turn off because at least *some* amount of sharpening is deemed necessary. If you went out of your way to turn it off completely, it might explain the discrepancy you're seeing compared to other anons' scans.
But first things first: Are you sure it's a scan issue and not a negative issue (missed focus, lens aberrations, maybe curved film etc.)?
Have you tried another frame, maybe from another roll?
I'm saying this cause I think I see uneven sharpness on your frame, for instance mid-top right hand side, the branches and leaves appear a bit sharper than the rest, also foreground is blurrier than background, so it seems to be DoF + lens aberrations (or curved film) worsening the situation on top of whatever issue your scanner might have.
In any case, try a different frame, say one that the negative is not curled and that you know you nailed focus, with deep DoF and lens stopped down 2-3 stops.
Scan at 7200dpi with a small amount of sharpening (or the default).
Then resize with bicubic at half the size each dimension.
Open the resulting image and zoom at 100%.
How does it look?
A process like that will give you all the scanner has to give. You should be able to see the grain structure with pretty much any colour negative film. Also post here a crop so we can compare and have a reference.
If your scan is not sharp even then, it must be the scanner. Most possible issue focus being slightly off.
