Great.  The reason I asked is that the Kodak stereo camera
is notorious for "slow shutter".  In many Kodaks (all I have
tried myself) the shutter is slower than the indicated value.
What this means is that your pictures will be overexposed.
That's why you feel you have to underexposure Velvia.
If the camera shutter is accurate, I think Velvia is
perfectly saturated when shot at the 50 marked value.

No.  It seems that quite a few photographers shoot it
as ASA 40.  It's been a while since I used Velvia
myself.  I prefer the ASA 100 films.  I find the
extra f-stop (over a ASA 50 film) quite useful.
