[Leica] geebee Ilford SFX processing

[leicam4pro at yahoo.com (John Biava)]

I have not been active with the cameras much since the eye surgery.  I 
remember a kodak B&W Infared and also an Ektachrome IR that was used for 
false colors.  It was originally a military surveilance film.  Don't know 
what is available now or in the UK.
   
  But the Leica IR filters appear almost black and are nearly opaque to 
visible light.

John,

I have a Leitz IR filter in 48mm for my 90 cron which I had completely 
forgotten until I read your post so I may have to revisit 
SFX. I think also that SFX just has heightened sensitivity to red but isn't 
a true IR film.
