[Leica] geebee Ilford SFX processing

[leicam4pro at yahoo.com (John Biava)]

IR photography is a matter of bracketing because there are so many variables 
you cannot control.
   
  Absorbtion and reflectance are things you cannot see.
   
  The exact characteristics of the filter you are using also make a big 
difference.  A R 25 is not really an IR filter, but seems to be about all 
that is readily available now.
   
  Anyone have a current B+W and / or Heliopan catalog ?  Since photography 
has lost its importance to home computers many sources are no longer in 
business.  Anyone know of other reliable sources for filters ?
   
  Leica had some IR filters in the past.  They were nearly opaque and often 
looked black.
   
  different manufacturer's films have different IR sensitivity.  Previously 
there were special IR films available, even ifg only on special order.  I do 
not know what the situation is now.

Jack,

I use a 3 stop compensation red filter and exposed the current shots as per 
Ilfords' rating of 200ASA. On a previous occasion 
shown below I rated it at 100ASA. The processing I leave to Ilford via pre 
paid mailers. I have never obtained the kind of results 
that I saw in someone else's work that first prompted me to try it so 
results may vary.
