Oh geez the question about scanning .. I will make some 5x7 prints out, will make 1 and see how it goes then 4 more of the same, giving some prints to friends ....
I knew Apug doesn't discuss about scanning. I was just talking abou the grain in general compared to other films (neg film) and compared to say slide, I have shot Velvia and E100G. You know ... commercial/portrait photographers who produced fresh pink skin grainfree and how clients may have requested A3 prints. And maybe, how did those pro's produce their prints.
I don't know many that have color darkrooms, the few that have b/w darkrooms only do b/w.
All I do is just use a professional lab, we only have maybe 3x of them in my city, 1 is a lab alone the other two sells various camera equipment as well. Only one lab in my city does slides now. Obviously all the labs are not optical. I don't think my country have them. This pro lab in my place does $30US for C41 D+P, they use a Kodak Nortisu machine.
In regards to the film I just shot, don't know but I am 98% sure they just use a minilab machine. At least they gave me by mistake some index prints for free - the back said Fuji Crystal Archive. In terms of the blix etc .. don't know. I guess they probably just use whatever chemicals for the Fuji Frontier machine.
Edit - I assume many professionals didn't use colour darkroom. Maybe they just drop them at their lab and people there got it done by them? Maybe the lab was large enough to have some people who adjusted the colours for them ...... I am also assuming that they just shot the film ... took accepted whatever properties at the time and just got prints made for the client. Maybe some pro's chose to shoot 120 format, at least my graduation photographer did that in early 2000s. He did use a Nikon film camera but that was for my passport photograph.

Regarding grain in general, it shows in the zones where the film density is higher: in slide film that means the shadows and in negative film that means the highlights.
Again, more in general, the human eye tend to notice and find more objectionable the grain when visible in the highlights then when visible in the shadows.
If grain is a concern to you, and your subjects are landscapes, where you often have large estates of blue sky, then slides could be a better choice to reduce grain (which I perceive as a nuisance, as many).
For portraits grain is not a big problem as it would show mainly on the face and would tend to somehow reduce the "imperfections" of skin which are so much more noticeable in picture than in real life.
All this said in very general terms, and your mileage may vary.
Really? Think about it.

I have a ton of Pro 160S that's in the freezer and I may shoot some this weekend. I have used cold stored NPS, the earlier verion of the professional portrait emulsion, and it has what I shall refer to as "variable grain" - grainy shadows but not bad elsewhere. In my experience this often happens when an older film is underexposed and the dye cloud in the shadow areas of the negative is very thin. one problem with using older emulsions is that they may have lost some speed. If I use my 160S this weekend, I will likely shoot it at 125 ASA or even 100 ASA, as while it is frozen, it expired in 2009 and may have lost some speed, and if not, should accommodate a 1/3 or 2/3 stop overexposure.
More generally, I have found many emulsions that print well in the darkroom but scan horribly. For the most part they are films that were formulated before scanning was widespread (eg Ferrania 200, frozen, but expired 1987).
Why are you asking me that question? That's a discussion you should have with the admin. I don't disagree with you.

If you set the spot size correctly on the drum scanner you can reduce or accentuate the appearance of grain. At least on the ones I've used. But enough on the scanning mechanics. I think we can all agree that to make digital prints from a negative it needs to be scanned, and of the scanners a good drum will give the best results.

If you want to isolate the grain, do a huge number of multi-pass scans and average them to remove the scan noise (vuescan can do this for you without extra interaction, or you can scan it over and over and stack the result in photoshop), the point here isn't scanning itself, but examing what part of that is actually grain, you can then make a judgement from there.
If still you want significantly finer grain at that point, you need to move up a format size to 645 for weddings, or try Portra 160 and Portra 400 which may work better for you (I found it has for me). Though if you plan on flatbed scanning MF, you will get less detail than your 35mm scans out of your coolscan sadly.
Then of course there is the issue of how well your lab is processing the film.
In any case, don't forget that viewing 100% crop is -MUCH- bigger enlargement than a print generally speaking. You're probably viewing it between 72 - 100 dpi on screen. So assuming 72 dpi (the standard figure), what you're looking at is what the grain would more or less look like in a 78x52 inch print viewing at a distance of approximately 50cm (same from monitor viewing distance). This simply isn't done.
When I got a 30x40" print done for a small gallery showing (matted to 30x36) viewing distance is approximately 1 metre to 1.5 metres for both myself and just about everybody looking at it.
