What can you do in 2d that cannot do in 3d

[P3D Dr. George A. Themelis <fj834@xxxxxxxxxxxxxxxxxxxxx>]

During the PSA convention in St. Charles, I was constantly reminded of the
things you can easily do in 2D but cannot do (or can only do with
specialized equipment and lots of effort) in 3D.

The Africa slide show that I attended showed pictures of birds in flight
taken with a 300/2.8 lens.  Try that in 3d! 

James Paradise spends a lot of time aligning 2D images to create a
successful montage by putting textures, suns, moons in 2D slides.  Try that
in 3d!  (It can only be done in a small fraction of the situations.  The
texture that blends well in a 2d image has to be placed somewhere in the 3d
space and that's a big challenge - I plan to write an article in Inside-3d
magazine about this.)

In my camera bag I can pack one camera body, a 24 mm lens,  a 100 mm macro
lens, and a 500 mm mirror lens and within minutes I can switch from
wide-angle landscapes, to portraits, to 1x macros, to distant wildlife and
moon pictures.   Try that in 3d!

In St. Charles I took a Realist, a Belplasca and my twin Minolta X-700s
with 45 mm lenses and one 24 mm lens.  Despite the fact that I was carrying
4 camera bodies and 7 lenses (I am counting 2 lenses on each stereo
camera), I could not do some basic things like take close-up portraits of
the models (for that I would need the bottom-to-bottom Konicas with longer
lenses) or take close-ups/macros of tabletops they had in the workshops
(for that I would need my 50 mm macro lens, a tripod and a slide bar).  And
yet, a 2d photographer with one camera body and one lens (35-80 zoom macro
lens) could have covered all these situations.

I agree with Ron... 2D is too easy to do.  Many of the subjects/techniques
photographed/applied in 2d are nearly impossible to do in 3d.  Stereo is a
challenge.  That's why we love it!
