Re: HIE in 120/220

In a message dated 00-03-03 12:31:32 EST, you write:

<< I have heard a similar report about 120 format Kodak IR for the 
 French defense department....but, as in your note above, I am not 
 sure whether this was HIE or an older emulsion (the 'high speed' is 
 not just a marketing gimmick, the predecessor was really slow, close 
 to Konica (or even slower?). >>

My screen is all red.  Hope yours isn't.  Oh, well.   My 1945 Kodak Films 
Data Book (I'm sure you all have one)  lists the IR film as having a Tungsten 
Film Exposure Index (ASA, I'm sure) of 8, when taken through a #25 filter.  
As expected, they don't quote a daylight rating.  By the way, the 120 rolls  
were six exposures, so that would be 9 for a square format and 12 for my 
Dad's old Kodak Duo-620.
