Two recent topics I might add $0.02 worth:

(a) Freezing film.  I assumed everyone who sticks film in the fridge or
freezer would not want to let it warm up and then stick back into the fridge
or freezer UNLESS it was still wrapped up in the foil wrap.  I've always
believed (!) that the foil wrap provided an airtight seal and had a dry
atmosphere inside.  If that's true, then sticking it back into the fridge
will not result in condensation on the film.  

    Of course, that has to be true!  Otherwise you could never stick into
the fridge, unless it was shipped on dry ice to you.  Ergo, it is safe to
stick it back in the fridge or freezer only if it's still sealed up in the
foil wrap.... if that foil is broken, it's not safe... condensation is a risk.

(2) One of the REALLY NEAT features of a TLR such as Rolleiflex is that one
can just leave the red filter on the taking lens and still see to focus.
It's still my favorite camera!  I would also be VERY INTERESTED if the
focus-corrected filter for Rollei exists!!  What a neat idea.  

There is a very simple way to tell if the filter is focus corrected or not:
hold it up so that you can see a reflection in the filter (off the camera).
Try both sides.  If the reflected image is true, then there is no focus
correction.  I think this is a sensitive test.... try it with a weak
"close-up" lens!     

If anyone has a focus corrected filter for Rollei, I'm interested in buying
it.  If Kodak would only sell HIE in 120!!  Do you suppose Kodak reads this
list??!  David
