errr...the camera did most of the work
wat i mean is, to avoid noise for the D30 at high ISO, try to make the histogram full, that is, get a good exposure and avoid underexposure at all cost. Noise may be visible in the shadow areas of the image, but as long as the main subject is correctly exposed, it shouldn't distract too much from the overall image....
well, actually, the D30 at ISO 800 produces very acceptable pictures with acceptable levels of noise (which looks like film grain really, but better...)........for a picture that is correctly and well exposed, at A3 sized prints from Epson photo printer, ISO 800 shots are still very good. i have one such print.....
I don't do it as often nowadays (esp for black and white pics) but i do sometimes run ISO 800 and ISO 1600 images through Fred Miranda's excellent isoR noise reducer photoshop action. There are many such noise reducers around (some free, some not so free) which can help with noisy digital images. However, the compromise is some of them will make your images softer........
