Re: [APML] TP Pre Rinse

["Andrew Schott" <aschott@cfl.rr.com>]

Should have mentioned in previous post, I have no experience with hypered
film.  Sorry.  I don't see how it can hurt, although I just read another
reader who testifies that the presoaking reacts negatively with the hypering
process.  I could understand this if the film was going to be stored.... If
moisture is detrimental to the hypering process, and presoaking hozes the
image, how the heck do you develop the film?  It's got to get wet in the
developer!  Are you telling me the image degrades in ten minutes of being
wet but not in 8 minutes of being developed?  There's something else going
on here....

Much more research is needed!
