There are a lot of techniques and plug-ins, and in-camera options, but I always struggled with noise in my black and white shots, esp the skies.
I wondered whether restricting the actual light going to the sensor with a physical filter (and therefore requiring a longer exposure) would be better than removing information gathered by the sensor after the shot was taken.
I had a little experiment tonight, with an orange filter, and the digital orange black and white filter setting on my K200D. There was much less noise with the physical filter. Tellingly the exposure was 1/15 with the physical filter attached rather than 1/45 using the digital setting.
I have increased the contrast on the following crops by the same amount, to slightly exaggerate the noise:
Physical:

Digital:

The Pentax is delivering a warmer colour but stupidly I left the AWB on, and in any case WB can be tweaked in RAW, so that doesn't really mean anthing!

Edit - Oh, and an understanding of light as well of course!
