Good slides can be made from negatives if you use a film designed for 
that purpose. The problem that would stop me from doing that on a regular 
basis is the color balance problem. Unless you pay big bucks for a pro 
job, the slides will be the positive equivilent of minilab 4x6s. Getting 
the same exposure and color balance on each of your stereo pair would be 
the problem. If you make 
prints you sometimes have to browbeat the printer to get matching prints 
(Grand Photo is the exception. They make it painless). 
If you were going to make an edition of slides, it would be worthwhile to 
go to a professional output bureau, negotiate the color balance, and put 
the time necessary to get great results. 
	I think the reason that color slide film is used widely 
professionally even with its disadvantages of higher contrast and limited 
exposure range is because the color balance is fixed and not subject to 
interpretation by an unknown third party.
