Re: 70mm things





>The Kodak web site mentions three variants of Aerochrome IR:
>2443, SO-134 and SO-060. All are processed in EA-5. 


The old Aerochrome 2443 film is optimized for altitudes less than 15,000' 
while SO-134 is optimized for altitudes greater than 15,000' and when 
enhanced IR effects are desired.  Note that SO-134 is not available in 
70mm, only in 9 1/2" wide X 200' lengths.

I also find it interesting that the recommended filtration for these films 
varies as to how it is processed.  As Kodak states in publication AS-69, 
"if rewind processing or stainless steel reel processing is to be used for 
processing these films, a filter change for exposing the film is required".

I hope to get my hands on the data sheet for the NEW 2443 soon.
