Hi Chuck,
Alright, a major snip of your long, excellent, explanation.
Some first results:
As for the settings: I set the T20s to manual, ISO 25, f4, just like
you said. The camera was now set to manual, 1/160th speed, and the
aperture and flash distances were adjusted, so as to get something
workable. The ISO setting was set to 100.
Shooting at about half a meter through the canvas, gave too little
light throughput, even when the aperture was all the way open at f5.6.
Moving the flashes closer (at some 20 centimetres) gave far better
results, especially at f5.6.
I then tried something else as a diffuser: a 'room separator' that's
made of light tanned cloths. Due to the folding mechanism, the set-up
had to be changed, and this time the flashes were set at a 45 degrees
angle from the front of the round. The results are very similar to
those of the canvas-diffuser-shots. Possibly the more powerful flashes
(i.e. T32 + T28 Twin) need to be used, or I might be better off using
thinner diffuser material.
I'm thinking of giving the cloth-design-tracing paper a go. That would
allow me to set the flashes further away, hopefully eliminating all
shadows (in the current test of some light shadows are still visible).
Some sample pictures (note that in none of these the WB was set
customly, so these should just be observed as examples of what the set-
up more or less does):
1) http://www.millennics.com/test/PA035697.JPG
E-500 + 14-45 F3.5-5.6, Manual, 1/160 @ f5.6, ISO 100, two T20s, one
to the left, one to the right of the subject, both firing through
canvas diffusers, distance from flash to diffuser +/- 20 cm, distance
of diffuser to subject +/- 25 cm.
2) http://www.millennics.com/test/PA035703.JPG
E-500 + 14-45 F3.5-5.6, Manual, 1/160 @ f5.6, ISO 100, two T20s, set-
up at a 45 angle degree from the front of the subject, both firing
through cloth diffusers, distance from flash to diffuser +/- 25 cm,
distance of diffuser to subject +/- 25 cm.
Then some pictures of the second set-up:

Well then, so much for the first trials...
I very much welcome further comments and tips. :P
Next up: trying thinner diffusing material and setting the flashes a
bit higher (hopefully eliminating the slightly darker 'bar' on the top
of the round)...
Cheers,
Olafo
