I'm not referring to grains of silver, which are much, much smaller. Anyway, the appearance of grain depends how how the film inherently is, as well as how it's scanned. People talk about grain aliasing and hard/soft light sources, and maybe that's it, but whatever the explanation, some scanning systems really exaggerate film grain more than others. For example, I had a Nikon Coolscan V. It was a very good 35mm film scanner, at least with fine-grained film. But with grainy film, say, Bergger 200 or HIE, it wasn't as good as my Canoscan 9950F, a consumer desktop scanner. The grain with the Nikon with those films was massive. It clearly limited system resolution. With the 9950f, those films had much finer grain but also more subject detail. Moving on to today, with 35mm film I scan at 6000spi with my Cezanne, not because I get more subject detail, but because I get the finest appearance of grain. It's not that I don't like grain, at least with some pictures. I'm just pointing out that some systems increase apparent grain size more than others.
This is true. What I find with the films I use, HP5-400, Portra, Extar, Acros, Tmax and D100, is that if I have good exposure, then even at high scan resolutions, I get minimal grain, if I am off too much on exposure, then I get the grain starting to appear. Much like a digital file and underexposing it and trying to pull the shadows out of nothing, gets real noisy.

My last image I posted in the Image sharing was scanned at 6000dpi and resized to 300dpi at 16x20 (approx) and you can see it is a fairly smooth file (little grain) I prefer to scan at max resolution, save that linear raw tiff as my archive file and then If I want, I could resize it as first step to the size I plan to print and edit that file. Will be much smaller, there is another method outlined here https://www.onlandscape.co.uk/2012/0...our-photoshop/and pointed to by Ken Lee that allows you to work an a smaller version of your file and then apply to the image scanned at max dpi.

I havre the coolscan 4000 and about 5000 images to scan for archiving. Slides included and uncut roll film. Need to get the roll film adapter and the slide adapter, but they cost more than the scanner!
