P3D contest with prize!

[boris@xxxxxxxxxxxx (Boris Starosta)]

I posted this yesterday, but am informed that the digest containing it,
2589, may not have gone out properly.  So I am posting it again.  Sorry for
those who have already read this:




Now that we have dispensed with the "Realist Flawed?" debate (and I thank
Dr. T. for his gracious last words), I can direct my attention to an
excellent question posted a few digests ago by alert reader Dave Spacey.
Here we go with yet another thread to keep me warm at night.  And this one
should be a doozy:

Toe-in (or convergence of the cameras) and the resultant horrors of
keystone distortion have been discussed on P3D before.  When I first
started, I remember reading some caveats here and there about how toe-in
should be avoided, at the least.  All of this to prevent keystone
distortion.  It's a rule that seems to rank higher than sunny 16!

Here's a little exercise for the student.  Of the pictures on my 3D
Showcase, about half were done long ago (summer of 97), before I thought of
competing in the International Salons, and before I started worrying about
toe-in.  As a result, these are shot toed-in, and have the stereo window
set "in camera."  Therefore, these will exhibit keystoning.  Of course, the
keystoning is subtle, proven by the fact that not one of the many critics
on P3D has yet noticed it.  (It's also not as noticeable on-screen) So you
will have to look carefully for it.

The other half (approx.) of the views were done more recently (fall of 97),
after I had become more educated on the matter.  In a future post, I'll go
into detail on how I fixed the problem.  The solution does not involve use
of the computer.  All images in the 3D Showcase, unless they are obviously
blow-ups, are geometrically faithful, nearly full frame scans.

In fact, let's turn this exercise into a CONTEST...  Let me sweeten the
deal, to make it worth your while.  Let's all get our toes wet!

The winner will be the first person to email me with the correct answer to
this question:  which of my seven "Showcases" (i.e. Nude, Sculpture, etc.)
exhibit the earlier (toed-in) work?  You must identify all Showcases that
exhibit the toe-in material.  Partially correct entries will not be
considered.  No fair guessing based on the subject matter of the Showcases,
I want you to look for the keystoning.  When you post your entry to me, you
must use the subject line "Make my toes wet!"  to help me to differentiate
contest entries from general replies to this post.  You must carbon copy
your post to Dr.T. <DrT-3d@xxxxxxxxxxxxxxxxxxxxxxxxxxx>, who has kindly
offered to referee.  No entries will be accepted after Friday this week.
The winner will be announced no later than Saturday.

The winner will receive an _original_ Starosta slide pair of the subject of
his choosing, if possible.  If a particular image on the 3D Showcase is
desired, I will supply a high quality dupe.

I realize that the contest will not be entirely fair, as not everyone will
get this message at the same time.  Oh well, sorry about that.  Do the best
you can.  I'll announce the winner Sunday.

And above all, have fun!
