[Leica] Art Nouveau Glass - Lighting Question

[douglas.sharp at gmx.de (Douglas Sharp)]

Hello all,
I've set up the "high-tech studio" again to photograph some details of
what we think must be a French Art Nouveau/Art Deco bowl. My wife's
mother always said it was Rene Lalique, but as it is unsigned we have no
idea who made it.

Question 1) Any collectors out there who know its provenance?
Question 2) which lighting set-up is most effective for your tastes? Any 
other suggestions?

The "Studio"

  http://gallery.leica-users.org/New-Old-Pictures/Lalique_bowl
Lalique style bowl is lit from below and normal room lighting obliquely
from above daylight from top left.

Lit from below, daylight reflected from bottom right, tungsten from back
right via mirror.

as above with more tungsten reflected from mirror , see studio set up.

Less tungsten, more daylight, right fish highlighted with a maglite
from front right.

as above but maglite placed in the bowl at the right.

as before, maglite replaced by a broader beamed flahlight, the black
background is the body of the flashlight.

NO colour manipulation during processing , only sharpness and contrast
enhanced.

Hope you like them
cheers
Douglas
