I experimented a bit with the Konica IR last summer in both 35mm and 120
format. (I think I still have a roll of 35mm in the freezer.)
Assuming this is Konica IR 750, the peak sensitivity in the IR spectrum is
750 nm, with some sensitivity out to ~800nm. Kodak's HIE is sensitive to
900 nm, SFX peters out around 750 nm. The Konica IR is (was) a great
film - finer grained than HIE but much much slower. Konica also had an
anti-halation filter, the absence of which causes most of the handling
issues with HI.E So it is easier to handle but lacks the nice 'gauzy'
effect that the absence of the ant-haliation filter lends to HIE.

> A friend gave me my first roll of Konica IR film... here are
some photos
which I shot with it last week and finally had a chance to scan today.
Pentax SV with Super-Takumar f3.5/35mm
and Fisheye-Takumar f4/17mm

I used a red filter with the 35mm lens and the fisheye's internal orange
filter.
Whaddaya think?

Not to bad Jim.
The Konica seems a bit less harsh/grainy than the Kodak HIE i use, but
that can be a good
thing<g>
Contrast seems a bit more smoother to, but that may be from the difference
in wave lengths
that the
Konica and Kodak record.
Is'nt the Konica a bit less sensitive.??Not sure how to put that.:-)
Anyway nice work. I like # 5.
