P3D Re: world of non-ortho

I have done this for many years (still do it in every occassion)
but ortho remains my favorite means of stereoscopic expression.

Why?

I think Sam Smith (a.k.a. The 3D Hacker) said it best and I will leave
his message intentionally quoted as posted because it deserves to be
heard twice (as in stereo).

I may add two observations:

1. Hyper works when it is clearly hyper.  It does not work when it is
   used as a replacement of ortho.  What do I mean by that?  During
   one trip to Greece I went the beach and realized that I had 
   forgotten my Realist.  That's no bid deal, I thought, I will just
   use my twin Minolta X-700 side-to-side (6") to take pictures
   with my usual 45 mm lenses and just don't take anything close
   to the camera.  What a mistake!  The pictures look clearly
   hyper to my eyes and fail to capture the feeling of "being
   there" like my Realist would.  I wished I had never taken them.
   Hypers that are not clearly hypers work for me only when taken
   with longer lenses (details of buildings, etc.)

2. I tend to believe that those who are not bothered by the hyper
   nature of everyday scenes taken with the 6" separated SLRs side
   by side, primarily use prints and not slides.  My explanation is
   that viewing prints is not as a realistic experience as viewing 
   slides, but that is a pure speculation from my side.

LONG LIVE ORTHO!!!!
