Pour one out for the OG. Loved that stuff, even if it was expensive AF back in the early 2000s.
Non will ever equal or exceed the performance of the Kodak HIE Infra Red. Tricky to use, but get a good shot you will have an outstanding winner. With no antihalation layer the ghostly edges of a subject in the frame will never be equaled,

I agree. It's unfortunate that HIE was never made available in 120 rolls. I still has a box of 4143 4"x5" sheets and one IE color IR film in the freezer, they are certainly rotten now, but I don't want to discard them.
Here is one HIE taken in the '70. I loved that tree, now it has been cut down.

Konika IR 750, Fujica 6x9
Forgive me, as this isn't really "on topic" - but yesterday I discovered that my iPhone 15 Pro's sensor is highly sensitive to IR wavelengths. This image was made using a Hoya R72 filter held over the lens: iPhone IR
This is a widely known fact. Wrong forum btw.
It is indeed so.
And the given list already includes majority of Aviphot reworks/repackages.
Adox
Takes Aviphot 80, puts some work in it, and boosts pictorial ISO 1 stop, making a great ISO 50 film. Then selling it as HR-50 and Scala 50 for affordable price. I have no problems with this and congratulations for making sweet tech emulsion available for regular shooters.
Meanwhile everyone else on the list (except Ilford and Foma), probably Astrum included, just plain:
- Repackages either Aviphot 80 or 200;
- put their half or fully assed logos on it;
- without putting any additional work into it;
- often charging way higher prices than Adox;
- far too often lying that it's a "completely new emulsion, made for them" and I have some problems with this, but like that tech emulsion is available... I just avoid these resellers whenever possible.
This horse has already been beaten to death more than once, but more info on this practice here: https://www.photrio.com/forum/threa...-films-and-kentmere-100-and-400-films.196304/
Currently the IR response goes as this, starting with less sensitive: Fomapan R 100 < Ilford SFX 200 < Aviphot derivatives.
If you need Aviphot 200, cheapest iteration usually is Rollei Superpan 200 in bulk, but most expensive - Infrared 400. If Astrum turns out doing the same, then cheapest option would be to buy bulk from Ukraine.
Cute.
It is really neat. I wash it so: load fresh film in tank in darkness, then some baths with constant agitation:
- 10s in regular water;
- 10s in distilled water, discard;
- 10s in distilled water, keep for up to 10 films;
- finishing 30s in pure Isopropyl alcohol, stopping the Antihalation layer removal at the black layer, just before the blue starts washing off. 500ml IPA can handle 10 films easily;
- IPA treated film dries in minutes, respool.
Shoot ASAP to avoid fogging of prewashed film in storage.
You might find that the "sensitivity improved" a stop or so, because of the additional exposure from halation. Sharpness will be less too, but that isn't too important for the traditional "IR look".

Indeed. And dry with Imperial Stout!Ha, some people might think of a different liquid when washing film in IPA.
I do, yes:Do you have example images with film with the halation layer removed?
Indeed. And dry with Imperial Stout!
I do, yes:
And this might be useful too - every Infrared Film shot/sample I've uploaded:
P.S.
And here in general I have links to every film I've reversed and then some:

You'll find me exploring abandoned places and scenes off the beaten path - with Olympus OM-1n film camera in hands. Or in my bathroom where I employ adjusted Ilford Reversal Processing and turn my films into well-baked slides for projection, discovering what characteristics each film has to...flickr.com
Yeah, don't be me, be wiserThanks, Ivo, nice work. That's crazy about the elevator mechanism crashing down on you.
I agree about the benefits of Adox HR-50. It may be the best IR film in 35 mm because of the Speed Boost treatment, which mitigates the extreme contrast that bedevils aerial films. Hopefully, they will make it in medium format in the future.
Make sure to let all of us here know how well it works. At least one person is interested in how well it works. Me!
