A very different lenticular enlargement

[P3D <PTWW@xxxxxxx>]

I sent the following yesterday but it hasn't appeared in any of my
digests.  Sorry if it is a duplicate to anyone.

While I was admiring the 3D eagle lenticular at the flea market, the
vendor came over and mentioned that the one he really liked was the
10x13 of some "parrots," which I had not previously noticed.  (He
also had two framed postcard-sized lenticular prints, which didn't
catch my interest enough for me to even say what the subject matter
may have been.)  The main subject of this other image is two highly
colorful macaws on a tree limb; one macaw faces forward, the other
mostly backward; you can see one side of each bird's head.  The
tree limb runs left-right across the foreground, as opposed to the
tree on which the eagle was perched, which runs along the z-axis.
All or part of 8 other macaws are visible in the backgound at two
different depth levels.  The separation between the foreground birds
and the background birds is very good, but the separation between the
two branches on which the background birds sit is poor.  There is a
more distant background of a very dense "wall" of green leaves, almost
like a very tall hedge.  There are also some long, thin, tropical plant
leaves in the lower foreground in front of the main subject.

The farthest background wall of leaves is out of focus, which works
effectively in this image; in fact I suspect it could have been even
more out of focus without being a problem.  Unfortunately, all 8 of
the background macaws are also out of focus, which in this image
strikes me as a major shortcoming.

The two pictures have interesting differences, some of which I *think*
I understand and can verbalize better as a result of Gabriel's timely
posting in digest 1785 about lenticular types.  (Thanks, Gabriel!  And
please correct me if I don't understand this properly.) I had not
previously heard of the distinction between "Layered Depth" and "Full
Depth."  I am sure the eagle picture described earlier must be full
depth; I suspect the macaw picture might be layered depth.  Although
the foreground macaws exhibit some depth (the forward-facing bird's
beak does clearly protrude from the scene), the image gives a strong
sensation of looking at three sets of 2 dimensional images placed at
three points along the z-axis, and the foreground macaws have something
of a cardboard cutout feeling about them.  The picture does not contain
any object that has any significant measurable z-axis dimension; it
seems highly probable that this composition was intentional, very much
as you might imagine a company would compose a scene to demonstrate the
strengths of the layered depth technology while concealing its inability
to recreate full depth.

Also, the picture of the eagle is mostly earth tones, which makes it
difficult to judge the color reproduction capability of the techonology
used for that image; the picture of the macaws has a lot of brilliant,
vibrant colors.  

Do any of the lenticular experts know if if there is a distinct
difference in color reproduction capabilities between layered and full
depth lenticular technology?
