Which reminds me... some people take stereo slides
and put shows together and the sound consists of
background music and narration.  How about some
"real" sounds?  I mean live recordings related to
the scenes you are showing?

Since I discovered minidiscs, I have been happily
recording stereo sounds any time I take stereo
pictures (sometimes I record stereo sounds in
situations where pictures are not allowed.)  I 
treat sound segments the same way I treat stereo 
pictures.  I am creating a collection of sounds to go 
with the pictures and use in future shows.  For example, 
in my "Easter in Athens" which I showed to my Greek 
students I was able to put live sounds from most slides 
I showed.  I think this beats a background of "Greek 
music" by a long run.

Minidisc players/recorders are widely available but
are not very popular in the USA.  You could get a
good one for $200 and minidiscs are about $2.  Mini
discs hold 76 minutes of near-CD quality stereo
sound.  You also need a stereo microphone.  Stereo
recordings that emulate the way we hear are known
as "binaural recordings" (not to be confused with
"stereo recordings".)  There are many similarities
with stereo photography.  For example, there are 
complex sounds that are not resolved well in 2D 
but become very clear in stereo.

I recommend minidiscs and binaural recordings to 
any one interested in stereo photography and anyone
who is captivated by the "being there" feeling of 
the stereo images.
