This was with the new film.  Remember, meters differ, unmetered amounts
of IR differ, what we are looking for differ, so we should always do our
own testing and come to our own conclusions.  I was using a yellow
Tiffen filter, which resulted in blue skys.  I spoke with Kodak about
this and we came to the conclusion that the Tiffen does not have a sharp
enough cutoff.
