[3dem] Problems with Kodak SO-163 film

[Norm Olson]

Thorsten:  The wavy patterns are interesting.  They look like 
something happened during a wet process.  Were the films adequately 
agitated during development?  The other thing, as Bob suggested, is 
that it could possibly be bad film.  How about taking a piece of film 
(or many films) from that batch and process it directly from the box, 
even without putting it in the desiccator.  Then do the same with a 
bunch of films from a totally different manufacturing batch.
