[photo-3d] Trick/Creative photography in 3d

["Dr. George A. Themelis" <drt-3d@xxxxxxx>]

Hello,

The Stereogram 5.8 (April 2001) was mailed yesterday
to subscribers and members and emailed to e-subscribers
(e-subscriptions are only $10 anywhere in the world).

In addition to the usual local club news, there is
a stereo biography of Al Sieg and an article by Jules
Rhine, "My Digital Stereo Camera".

The Tutorial deals with Trick photography in stereo.
Here are the highlights:

Trick photography in 3D is fascinating because the 
realism of stereo makes it more convincing and puzzling, 
compared to 2D trick photography.  But it also makes it 
more difficult to do.  We can distinguish the following 
areas of trick/creative photography:

- Unusual subject/composition
- Unusual lenses or lens attachments
- Unusual stereo base
- Unusual films/processing
- Multiple exposures (ME)
- ME with split fields
- As above, plus size/space control
- Photographic "sandwich"
- Darkroom manipulation
- Digital manipulation

Some of these areas are not strictly trick photography but 
can generate some very interesting results.  Examples follow.

*** Subject/Composition

- Look up or down or at an angle that makes the subject 
  unrecognizable.

- Turn the camera 90 degrees (works only with appropriate 
  subjects.)

- Long exposures or painting with light.  This technique can 
  generate bizarre or abstract images.

*** Lenses or Lens Attachments

- Long lenses make it look as if the subject is closer and 
  reduce distances between subjects (compression).

- Short lenses have the opposite effect.

- Various lens attachments (from simple filters to 
  kaleidoscopes) can generate unusual images.

*** Stereo Base

- Hyperstereo (large stereo base) makes an ordinary scene 
  look like a small-scale model.

- Hypostereo (short stereo base) makes small things look 
  bigger.

- Pseudostereo (negative stereo base, achieved by simply 
  reversing the L and R images) results in a depth reversal 
  which, with the appropriate subject, can be very effective.

*** Films/Processing

- Black & White film.  Since the world has color, B&W is 
  trick photography even though we don't think of it as such.

- Negative film for direct viewing (slides).  Regular negative 
  film leaves an orange mask.  A better choice is Kodak SO-279.  
  Normally this film is used to make slides from negatives.  But 
  if used as slide film in a stereo camera or to copy slides 
  instead of negatives, some very interesting results can come 
  out.

- Special processing.  A multiple of techniques are available 
  (solarization, posterization, etc.).  I do not have any 
  personal experience with these.

We will continue tomorrow with true trick stereo photography.
