Hi Olaf,
I can advise to buy a lighttent. Works a charm with flashes. Should work just
as great outside in the sun or even on an overcast day. I always use it with
the two flashheads of my macro flash set lying on the top side of the tent. I
bought my lighttent for €30,- from our local "Marktplaats", which you will know
also. I never always use the manual flash settings, which I tested by exposing
a greycard. I concluded that with 1/8th of the power I have good exposure with
f=6.3. Leaves plenty DOF with the E-1 and E-3.
If you want even less shadow, buy a sheet of plexyglass or real glass that fits
inside the lighttent. Place it on some styropor blocks to lift it off the
bottom. Eventually you can even add a small slave flash under the tent.

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:

extension!)

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
