It seems like you can rate it at almost any speed and tell your photo lab
how to develop it (or develop it yourself). I've shot at ASA 200,
daylight, with a 25 filter and got nice results.

This seems to vary depending on your camera and how much IR light is
available. When using the TTL meter on my Minolta SRT-101, red filter, and
setting the camera to what the meter recommends, the results are good. All
the shots that I've bracketed, the meter setting worked best.

I haven't tried other filters yet. Experiment, and have fun.
