The jpeg image you get from your camera depends on in-camera sharpening and noise reduction algorithms. If you look through camera comparisons, f.i. at , you'll see that different manufactures have different visions of this balance. Some of them prefer less aggressive noise reduction (Panasonic), some more (Kodak). So an jpeg image from Kodak camera looks smoothly with less noise, but with less details.

When you convert image from RAW with UFRaw, you get it closely to "as is" from camera matrix. Afterwards you can apply sharpening or/and noise reduction. Noise reduction plug-ins can be found at
or any other from the page

I'd recommend you selecting some "critical" parts (like faces) before applying noise reduction with greycstoration, overwise it would take a lot of time and memory.
