When you say a technological shift, what do you mean?  Do you mean thhe shift
from film to video?  16mm is becoming very hhard to get a hold of.  There aren't
too many cameras being made.  It seems that in order to teach a film production
class, you need 16mm.  The cameras are basicly the same as 35mm, but they are
obviously smaller.  Public perception wise, film is considered obsolete.  I
don't know how many times I've been asked why I'm studying film when "video
is going to take over."  It seems to me that it is more a public opinion
shift than a technological one.
