Light meters are sensitive to Infrared Radiation, but are not calibrated for
it.  I use the meter reading through my #25 filter as well as experience to
determine my exposure time.

Note that I said that I meter through the filter, so you can assume that this
is the meter within the camera.  Peo

As far as HIE is concerned, very generally, I meter through a #25 filter at EI
250.  Examples can be found on my Web site.
