Some sheet film holders do not have opaque slides. Look for a series of five
raised dots where you hold the slide to draw it. This indicates that the slide
is IR opaque. Without these five dots you're on your own.
Determining exposure for infrared is a personal choice. I place a #25 filter
over my meter and measure the light that way. I then expose EI 250, though
this will vary depending upon the season, the scene, the time of day, etc.
Experience will be your best guide, so bring your pen and paper and make notes
of each sheet. You can then determine what works for you and what does not.
BTW, my website is dedicated to Infrared, Pinhole, and Alternative Process
Photography.
