Re[2]: SFX with IR filter

["Peter Badcock" <pbadcock@xxxxxxxxxxxxxxx>]

The 89B is equivalent to the Hoya R72, this being the lowest cut-off frequency 
filter useable with SFX.  Be prepared for LONG exposure times.  Although I 
haven't used this filter with SFX myself I've heard that even in bright daylight
hand holding is just not an option.

regards
Peter

I can't remember (and I'm in the midst of packing so don't have time to look) 
if the 89A or 89B is the same as an R72, but the R72 will work.  I shot a lot 
of it with this filter, also a number 29.  But the 87 is much too opaque for 
the upper sensitivity levels of SFX film.
