The 4X5 version os HSI.  You don't need to have the filter in place when
focusing - it can be placed over the lens after focusing.  I seldom focus
correct, as I generally tend to stop down to f16 or f22.

Your bellows should be tested, as not all view cameras have IR-opaque bellows. 
I "think" that the Wisner has problems in this respect.  My Crown Graphic works
just fine.

You can tell if your holders have IR-opaque slides by looking at the part that
you use to pull the slide.  Five raised dots indicates that the slide is okay to
use.  My Riteway holders work just fine, though I've been told that my Fidelity
holders will leak like a sieve (they have eight raised dots).

When loading the film, be prepared to deal with the problems of film curvature
(if you've shot the 35mm version you'll have an idea as to what I'm talking
about).  Also, DEFINITELY wear latex gloves.  The oils on your fingers will
leave marks on the film (even if you diligently wash your hands beforehand).
