One solution I have used in the past when the "dark corners" were too dark
is to place a dim point source light in the scene at the exact location of
the camera.  The shadows that are introduced by the light can't be seen by
the camera (unless there is a reflective surface) so don't show up in the
image.

I use something like this:

#declare CamLocation = <20, 20, 10>

camera {
  location CamLocation
  look_at  <0, 0, 0>
  }

light_source {
  CamLocation
  Color White*0.5
  }

Its just a hack, I know.
