Hannu, the reason there is no difference using a no.25 or no.29 filter with
Konica infrared as compared to Kodak infrared, is that the Konica film has no
sensitivity to the 500-640nm range of the electromagnetic spectrum. Both
filters absorb light in that range, so there is no visible difference in
contrast in the images.
