The background is a problem in the barrier technology. It is O.K. if the
background is not very unclear. My problem is for the several main
objects which we would like to focus on. Background could be very
clearly separated with the "face" of the photos, even up to unlimited
distance. And the 3rd dimension is not only "depth" but also
"outstanding" out of the photos. The bigger size, the stronger the 3rd
dimension. The size of the samples I sent to Boris is a little too
small. When the size is double, their depths are deeper more than twice. 

I would like more professionals of 3 D photos to see our samples,
utilize our technology to create their great works and participate in
promotional activities to their clients.
