Kodak's data suggests ISO 80 for HIE. This refers to a hand-held meter, and
assumes a red or ir filter is on the camera lens. That is, don't add any
filter factor corrections to the ISO 80 reading!

For real-time SLR TTL metering, set the meter to 300 - 400 ISO with a red
filter. Or set the camera to 80 ISO and set the shutter/aperture without a
filter, then screw on the filter and expose.

I don't quite understand When you say ISO 300-400 do you mean ASA?
Or this is a different film speed scale.
