I'm curious about this, and my traditional darkroom knowledge is elementary. What method exists to reduce noise in a traditional darkroom? If I shoot a 3200 film, and my print has a lot of noise, how could I reduce it during the printing process?
More to the point, what's the traditional darkroom equivalent to Neat Image or Noise Ninja, etc?

I don't know how you call this in English, but with 3600 ISO film you don't get noise but .... (grain?) This is something they mostly use on purpose, because it's beautiful but you can't compair it to noise in digital photos.
The grain (?) is on the film itself and as far as I know there's no way you can reduce it during the printing process. Why would you? Grain is beautiful IMO ;)

| You can make the print very small and this will reduce the amount of grain you see but in most cases this is no good, you can use a soft focus filter on the enlarger, you can push developement time, you can also increase the contrast of the print. |

Grain is an inherent characteristic of film -- it refers to the actual granules of gelatin in which the light-sensitive silver compounds are carried.
In general, the higher the ISO (formerly ASA) number, the "faster" or more light-sensitive the film, and the larger the gelatin grains have to be.
The only way to "get rid" of grain would be to print out-of-focus. When using an enlarger, to check the focus, the photographer doesn't look at the image but at the grains (with a magnifier) to see if they are in focus. |

| I'm sorry, I don't know lots about the darkroom... |

...generally speaking, if one wanted a more detailed less grainy film image, one would move up to a larger format camera which would allow for more enlargment before the grain would be more visible/obvious...contact prints using an 8 by 10 view camera negative are quite lovely...
...so this makes me think...why are noise/grain and even simple textures so offensive to some in the digital realm yet perfectly acceptable and often desired in the film realm?
...makes ya think...

My line of query is related to the above statement, and to the idea that beyond thinking that grain/noise is "bad," there is a trend here lately to think that grainless/noiseless is "good."
We're interacting in a digital photo site, so I suppose we're not bound by the "if you can't do it in a traditional darkroom, then you can't do it in photoshop, etc" concept. But is there room left here for SOME noise?

| I think the problem isn't so much the visible noise, but the odd colors it takes on in digital. That's why "grainy" B&W digital photos usually look OK, but a "noisy" sunset looks like garbage. |

Grainy sunset doesn't look too pretty either :) |

Really as some have said ... film selection is much more critical in film because each film stock has different characteristics and grain patterns...
If you were worried about grain you would not be shooting a 3200 film
unless you WANTED the grain....
As for sharpness you can do a USM process but believe me it is much more of a pain in film than just hitting the button in PS
