I used TTF (through the lens with filter) metering with Canon EOS 600.
The filter was Hoya 25A red, which should be equivalent to Wratten #25.
In the camera I has EI 400 and I bracketed +/1 f-stop.

Normally I use Konica IR 750 outdoors with EI 100 metered
the same way.

This experiment shows, that I can use EI 200 - EI 400 with tungsten
lights.
