Close-up 3d of plants & flowers

[P3D <hans@xxxxxxxxxxxxxxxxxxxxxx>]

Does anyone in the group have experience in taking close-ups say at
12 to 18 inches (300-450mm) of flowers and plants.

My questions about this are as follows:
(a) What is the most economical method of doing this.
(b) Most stereo pairs have a seperation of 2.5 inches (6cm), how much 
more or less should this distance be changed.
(c) If two cameras were used at a seperation of 2.5 inches, would 
both be angled inwards towards the subject to keep the object centred 
in both viewfinders?
(d) How succesful would a close-up lens with a Pentax beam splitter 
or similar work?

Any suggestions gratefully received.
