[APML] Electro-Static Discharge and hypered 120 format Tech Pan

["Steve..." <swalters@att.net>]

I have found little crescents here and there on some developed hypered 120
format Tech Pan film that I think are caused by electrostatic discharge
(ESD) when I remove the paper backing.

So, my question is this: Of those who are hypering 120 format Tech Pan and
then removing the paper, what are you doing to avoid ESD?

Here are some aspects of the problem I have:

- I must leave the paper backing on when hypering or I get uneven hypering
of the film. I think this is pretty common knowledge and I have definitely
demonstrated it by trying. I get "bands" on the film.

- I must remove the paper before using the film because I have a vacuum
camera back that would be defeated if the paper was left on.

- After hypering, the film and paper are highly dessicated (dry) which makes
ESD more likely. It's like pulling socks apart after they come out of a
dryer. Zapppp....

Any suggestions?

Thanks!
