Deduct sum of both factors from 11.
Subtract 1 for each hour before 10 AM and after 2 PM.
Result will be f/number.
Example:  Suppose you are using Copex rated at 32 ASA on a soft sunlit day 
in Sept. You add 1 and 2 and deduct the sum from 11 and the result is 8.  You 
set the shutter speed to 1/60 and the f/stop to 8.  If you are using Copex at 
64 ASA then increase aperature 1 f/stop to f/11.
