Sharpening the grain makes the image a bit noisy looking.
I think you're right. I've noticed the same thing with my 645 scans at 1125 dpi: They make prints as good as 35mm scanned into much larger files. I believe that the because relative low-res scanning of medium format can't resolve grain, it gives a result similar to digital (in comparison to scanned 35mm film) in all three areas you describe: * They can handle more unsharp masking * They tolerate being "res'd up" better * They make satisfactory prints at much lower ppi settings
I use Photoshop's "Smart Blur" filter to smooth out the grain. It works well if you're careful, and it makes an unsharp mask a lot easier.
I usually start with these settings and adjust as necessary (I scan at 2400ppi):
radius 1.7, threshold 3.4, quality "high".
The only thing that annoys me about this filter is that you can't preview it on the whole image. It also requires a fair bit of processing so may take a while on older machines.
