Extend the bellows "slightly." If you are stopping down, chances are real good that
depth of field will take care of everything.

Everyone is looking for their own results. The images on my Web page are examples of
shooting between about EI 50 and 400, metered through a #25 filter. The low
contrast, "ethereal" images are shot at the slower speeds. I used D76 (1+1), but
have switched to Rodinal for HSI (HIE works very nicely with Xtol). Needless to say,
you'll need to do your own experiments. Remember, however, that we are falling out
of "IR season." This doesn't mean to stop shooting (I continue shooting IR through
the winter), but next year between about April and September much more IR will be
available, so you'll need to consider that when determining exposure.
