Hmm, I shoot raw files (no jpg), and have no problems with Rawtherapee's noise
reduction. I do my conversions to 16-bit per channel TIFF in Rawtherapee, then
feed that into Hugin.
In my experience, the amount and type of noise reduction needed varies from
image to image, even the same ISO. The amount of contrast in the scene, how
bright and dark things are, produces different types (and degrees) of noise.
My Sony A58 and my previous Minolta 7D both use 16-bit per channel sensors, but
only output 12-14 bit RAW files. I think in-camera noise reduction is done on
the 16-bit image data, right? I think that's the one point where in-camera
could do a better job, only with much less control over how it's done.
