I am glad that both Matt and 2F/2F clarified this for Allen. Rather than rehash what they said in a different way, I will just add that not only do I agree with them, but I do the equivalent thing, as I posted earlier in post #7, by setting the internal light meter of my SLR to the box speed and meter with the filter on.

Allen, since IR film gets expensive, please feel free to ask questions.
