I got my B+W 099 filter in today, just a bit before. It is a light orange, darker yellow color filter. First thing I did was test it with my spot meter, with it over the lens, and off. Its only about ~2/3 stop. I suspect it will act exactly like a orange filter on both Pan and IR films lol. The literature indicated its supposed to be used with color IR films. I will try some film with it this weekend. The same seller had the 092 which I totally didnt see which sold for really cheap too. Kinda kicking myself for that one, Alas I will keep using a cheapo 720nm IR filter I have.
