Rollei problem)
That portrait by CarlosMF was taken with the 'cord IV, Plus
X developed in Tetenal 1+4 using a Vivitar 283 flash at 45º
rebounding on the white ceiling and wall, I think the camera
controlled the internal reflections very well (BTW, if the
baffles are not good after 55 years, any solution using
newer materials will be better than the old one):

I suspect there may be a more light absorptive finish
than whatever Rollei used. Not sure about that, the finish
is pretty dead but there are some reflections especially
from the knife edges of the baffles. My old standard has
considerable internal reflection, very obvious when
inspecting the interior but it doesn't seem to affect the
images that much. As Eric points out its easy to fix. I
think Rollei was quite aware of the importance of reducing
internal reflections as witness the baffles and the
excellent lens shade. No matter how good the lens coating is
reflections from the interior of the camera can cause a lot
of flare and undo the good of the coating.
