[APML] Dumb Hypering Question :)

[Michael Greger <mgreger@dashmail.net>]

After seeing some of Tony's recent results as well as those of others
(incredible pictures, BTW), I decided to give hypering a try.

OK, one dumb question...  Some of you, including Tony, hyper on an open
reel.  How do you get the film on the reel into the hypering chamber?  I
have a Lumicon model 600 and the instructions suggest that you pre-heat
the chamber for 4 hours to allow it to reach temperature.  I could put
the heated chamber into my large changing bag to load the film, but it
gets quite hot (I did not realize how how 50 C was...).  So, it this
what you guys do?  Or, are you simply loading in a dark room?  The only
other alternative I can imagine is that you put the chamber in the
changing bag before heating, put the film in the chamber, and then begin
to heat it.  Once the chamber is at 50 C four hours later, start the
hypering process...  So which is it?

Also, I have seen conflicting reports on hypering in the canister vs. on
an open reel.  Lumicon suggests that it can take much, much more time
(up to several days vs a few hours) to hyper in the canister.  I have
also seen reports of uneven hypering in the canister.  But, I have also
found reports that some are hypering in a canister for times somewhere
around those suggested by Lumicon for an open reel.  So, what is the
concensus?

Finally, while searching the APML archives, I found a survey of hypering
times for various films.  Several people responded.  Is anyone aware of
a database on the web, perhaps based on the responses to this survey, of
hypering times used by amateurs?  Seems like it would be a useful thing
to keep track of...

Thanks,
Mike
