Thanks for the affirmation that I am indeed real. 
Although people have told me I'm out of synch with
reality, for the most part I'm pretty down to earth.

The 220 HIE that I sell can be loaded in subdued light
(for example inside your house about 4 or 5 feet away
from a 60 watt light bulb).  I've never tried loading
it in direct sunlight; to do so would  be too risky. 
It's true that HIE fogs quite easily, and for the work
that I do (mostly landscapes) I still usually use a
changing bag to load the film, just to be extra safe. 


B&W 35mm IR film must be loaded in darkness because
the felt trap is not light tight. However for 220 size
film there is not a  felt trap and the backing paper
is IR opaque.  Therefore the only way light can get to
the film is inbetween the edge of the film and the
plastic spool.  If your paper is wound tight and you
load your film properly you won't experience fogging
at normal exposure indexes.  If you are pushing this
film two or three stops some fogging may appear (Have
never tried pushing HIE and don't know many people who
have even tried it, much less two or three stops.) 

Thus for critical scientific work I would always
recommend loading and unloading in complete darkness. 
Just like people do with Color IR film.  (As a side
note the felt  trap on a roll of 35mm Color IR film,
EIR, does leak IR radiation, but it doesn't effect the
film that much because emulsions that are sensitive to
visible light cover the IR sensitive emulsion.  If you
want to prove this just use an EI of 800 and do a two
stop push  developing.  Your first couple of frames
will be fogged red!) Thus Kodak's recommendation to
only load EIR in complete darkness, although most of
us load it under subdued light and get great results.

Hope this information sheds some light on the topic of
why HIE fogs so easily. Peace Rolland
