I have personaly obtained excellent results with Konica 120 and a #87
filter, albeit at long exposure times.  As I recall (I'd have too look this
up to be sure) my exposures were around 1/4 sec at f8 on a "typical" sunny
day.   The results were typical IR, but much finer grain than HIE.  I've
since gone over to using a $25 filter as a matter of convenience, but rest
assured, the #87 WILL work.  I have the pictures to prove it!

Since I'm somewhat on the subject, I would like to comment on the
comparisons people are making between HIE and the Konica and Ilford versions
of IR film.  I just tested a roll of SFX200 on a figure model in a studio.
The results were nowhere near what I would have obtained if I had used HIE,
but that doesn't bother me.  I still get that beautifull white tonality of
the skin, and the film is much sharper.  A side benefit is that the film hid
a number of skin blemishes that this particular model had  (When she see the
pictures, she will love them!).  Joe Paduano stated in an earlier post that
plus-x looks the same with a red filter in place; in my case, the effect was
strong enough that I don't think a normal panchromatic film would have given
me the same effect, with or without a filter.

As  much as I love the look of HIE, I am finding that more and more of the
published pictures I see taken with it are starting to look the same to me.
Please don't flame me on this, it's just a personal observation, and applies
to my own work in HIE as well.  SFX gives me a chance to get a slightly more
subdued look in IR that can still be striking and pleasing to the eye.  Try
the film; don't expect it to be identical to HIE, it doesn't have to be.
