Well, you've said you don't want to start a debate, but this is a pretty silly thing to say. Why is it pathetic? There are many people who enjoy or prefer or are forced to use digital photography (photojournalists, for example, in the world of modern journalism). One of the major complaints about digital photography is that it is unable to produce the "look" of a film-based print. Why would serious photographers in the digital realm not want to work towards achieving that look?
I think in all this talk about grain, there is one technique often overlooked. I use Rodinal - a LOT, and I am of the opinion (bash me if you will) that Rodinal does NOT increase or enhance grain - it is a clean-working developer that simply presents grain as it IS in the film, without mushing or moderating the silver itself or the spaces between. (Note 1)
I *love* having grain as an option. At times it is of aesthetic value, at times it is not. I have not subscribed to the "Can't be any slight suggestion of grain, or the photograph is automatically a failure" crowd - not since I first encountered Farber's beautiful!! Nude work where he pushed the living daylights out of Agfachrome 1000 (two and three stops) with the express purpose of making *very* grainy images.
So - to the technique. Some time ago, while searching the "Used Filter" bin of a large photography store, I came across two 40.5mm Softening filters. 40.5mm is the size that fits my Rodenstock enlarging lenses - so I bought both, for the sum of US$ 1.50 each. Truthfully, for no other reason than they fit the lenses.
These things can best be described as "grain removers". With them, apparent grain, and minor imperfections seemingly disappear. I have to be careful not to have either on the enlarger lens while focusing , because I will not be able to see grain in the Grain Focuser - it just will not be there!
My favorite combination is AgfaPan 400 in Rodinal (I can hear the gasps from the anti-grain crowd now). If I do not want to see grain in the final print, which happens most of the time in portraiture, I'll simply use one or both Softeners after focusing.
Ha! There Is a reason why they thread those enlarging lenses for filters!!
Note 1: Oversimplified I know. I don't want to provide fuel for the nit-picking crowd, so I'm trying to keep it really, really "general".

I may have the wrong end of the stick here...but I do know that threading a filter onto the back of a large format taking lens will shift the focus (which is why you should focus such images with the filter in place).
Thanks in advance for any information you choose to share on this.
Film is cheap. Opportunities are priceless.
Indeed. As a true Rodinal lover (surprise ) I use it because the grain is beautiful with Rodinal. Especially Tri-X, HP5, Delta 100 and FP4 have nice grain i Rodinal. I love it. I am a grainophile (cool word btw...).

Hmm... I once tried placing a Quartz Optical Flat - 2" (? or so) thick, with a high refractive index, in FRONT of a Hassleblad taking lens .. and there was *NO* shift in focus that I could see. In Back?? ... Hmmm... considering the ray trace .. the rays are diverging at greater angles ... so refraction COULD ... I think WOULD, cause a shift in focal length - and plane of focus. I suppose the same would happen in a projection (enlarging) lens, but probably the depth of focus would be sufficient to maintain the "circle of confusion". At any rate, it is hard to tell - critical focusing is very difficult without the grain itself.

BTW ... what was the topic? I read "grain" ... possibly, now, I have a built-in personal anti- "digital vs. film" filter.

On this side-issue: behind-the-lens filters shift the point of focus by differing amounts depending on the angle the ray makes to the plane of the filter - so that there is no longer a true point of focus and there will be an apparent focus shift as the lens is stopped down. The effect is imperceptible with thin filters. Perhaps the best known example of it is when a thick beamsplitter is used between the lens and the film, as in Bolex H-16 reflex movie cameras.
