Thanks!  I remember long ago seeing that in the documentation and being
annoyed that it wasn't in the camera menu system and concluding it was
about some different model.

But I checked again and it is right there where it is supposed to be.
Somehow I have been failing to notice it all this time.

I quickly took a picture that needs more range than jpg has.  Simply
viewing the arw with the microsoft viewer shows just as much noise in the
dark areas as I'm used to.  But converting arw to tiff with rawtherapee
gave me much better results than I'm used to.  The result still has more
noise than the JPG but only a little bit more.  So the compression seems to
be destroying information needed for noise reduction, and I've been using
raw incorrectly all this time.
