Seems to me it's more of a color balance issue than a sensitivity 
issue. My unhypered PJM has good sensitivity but usually
has a magenta cast. Mr. Perkins and others using hypered
PJM are not having this on their web-site photos. I have also
seen a difference in color balance with hypered and unhypered PPF.
