Tony, could you elaborate on this please?  Are you saying that lenticulars
and these barrier strip prints cannot under any circumstances have
sharpness very far away from the level of the actual printed surface?  Does
this also hold true for autostereoscopic video displays?

I am presently examining two of Mr. Shen's prints.  They are quite
dramatic.  I did notice that depth of field appeared to be lacking, and
thought it was just due to the camera depth of field.  But you appear to be
saying that there is no way to get sharpness and depth.

The prints I have are about ten by twelve inches, best viewed from five to
six foot range.  One of them exhibits a good semi-orthoscopic image with
about fifteen inches of apparent depth.  A lot more than the similar-sized
back-lit 1950s era lenticular that I have.  But it is quite blurry towards
the "back."

Congratulations to Mr. Shen on these nice prints.  I am impressed.

Boris
