Hi Jeremy,
Not necessarily in every case. You can "section" the fractal, i..e. intersect
the 3D set with a 2D plane and analyse the intersection instead (called the
zerset, then add 1 to the value of the FD result). There is a theorem for
that, but I do not have the reference at hand right now.
I agree that one cannot do that directly from the photo, but maybe they could
illuminate the 3D object with a "laser sheet" to obtain the zeroset that way.

Cheers

Gabriel
