You've listed two of the three classifications for OCC's PSA 
International Stereo Exhibition (open competition) this year.  
The third classification is the general classification (called 
"Contemporary").  So all you slide bar folks have a chance to 
win big!  8-)  Actually, the classifications are "macro" (where 
macro is defined as "Picture area must be less than 4" x 6" 
(10 x 15 cm)") and "architectural interiors".

Big plusses!  The availability of longer lenses lets you follow 
Ferwerda's advice and use a longer camera lens (around 70 mm is 
his suggestion) for pairs that are to be projected.  He advises 
this because the audience sits relatively far from the screen.  
Also, you can easily find and use very high quality lenses which 
many stereo cameras don't have.  

If you need an application form for the International Stereo 
Exhibition (don't worry, the application fee is low), write to me 
(BERCOV@xxxxxxxxxx) or to Eddie Hosey (EHH@xxxxxxxxxxxxx).
