Dwight, remember that Konica infrared is sensitive to 820nm, it peaks at
750nm, so the 87 filter I believe passes infrared at about 820nm and beyond,
producing the results you achieved. Try using a no. 88 infrared filter
instead, which will allow lower infrared wavelengths to pass, to which the
film is sensitive. You should see better results. p.s. there is some
information in Whites book that is not correct, so personal experimentation
has a lot going for it.
