Dear Ed:
We would like to determine if we need to adjust exposure
time to compensate for changes of film sensitivity due to film
temperature changes. Therefore, we would appreciate any available
data of 50-132 film sensitivity as a function of temperature. If
the information is not available, do you plan to obtain the data?
Approved For Release 2006104/13: CIA-RDP67BOO51 1 R0001 00180061-5
